-- Title : Standard VHDL Synthesis Packages
-- : (NUMERIC_STD package declaration)
-- :
-- Library : This package shall be compiled into a library
-- : symbolically named IEEE.
-- :
-- Developers: IEEE DASC Synthesis Working Group,
-- : Accellera VHDL-TC, and IEEE P1076 Working Group
-- :
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNRESOLVED_UNSIGNED: represents an UNSIGNED number
-- : in vector form
-- : -- > UNRESOLVED_SIGNED: represents a SIGNED number
-- : in vector form
-- : The base element type is type STD_ULOGIC.
-- : Aliases U_UNSIGNED and U_SIGNED are defined for the types
-- : UNRESOLVED_UNSIGNED and UNRESOLVED_SIGNED, respectively.
-- : Two numeric subtypes are defined:
-- : -- > UNSIGNED: represents UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The element subtypes are the same subtype as STD_LOGIC.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array
-- : is returned (exceptions, if any, are noted individually).
--
-- Note : This package may be modified to include additional data
-- : required by tools, but it must in no way change the
-- : external interfaces or simulation behavior of the
-- : description. It is permissible to add comments and/or
-- : attributes to the package declarations, but not to change
-- : or delete any original lines of the package declaration.
-- : The package body may be changed only in accordance with
-- : the terms of Clause 16 of this standard.

-- Title : Standard VHDL Synthesis Packages
-- : (NUMERIC_STD package declaration)
-- :
-- Library : This package shall be compiled into a library
-- : symbolically named IEEE.
-- :
-- Developers: IEEE DASC Synthesis Working Group,
-- : Accellera VHDL-TC, and IEEE P1076 Working Group
-- :
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNRESOLVED_UNSIGNED: represents an UNSIGNED number
-- : in vector form
-- : -- > UNRESOLVED_SIGNED: represents a SIGNED number
-- : in vector form
-- : The base element type is type STD_ULOGIC.
-- : Aliases U_UNSIGNED and U_SIGNED are defined for the types
-- : UNRESOLVED_UNSIGNED and UNRESOLVED_SIGNED, respectively.
-- : Two numeric subtypes are defined:
-- : -- > UNSIGNED: represents UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The element subtypes are the same subtype as STD_LOGIC.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array
-- : is returned (exceptions, if any, are noted individually).
--
-- Note : This package may be modified to include additional data
-- : required by tools, but it must in no way change the
-- : external interfaces or simulation behavior of the
-- : description. It is permissible to add comments and/or
-- : attributes to the package declarations, but not to change
-- : or delete any original lines of the package declaration.
-- : The package body may be changed only in accordance with
-- : the terms of Clause 16 of this standard.

-- Title : Standard VHDL Synthesis Packages
-- : (NUMERIC_STD package declaration)
-- :
-- Library : This package shall be compiled into a library
-- : symbolically named IEEE.
-- :
-- Developers: IEEE DASC Synthesis Working Group,
-- : Accellera VHDL-TC, and IEEE P1076 Working Group
-- :
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNRESOLVED_UNSIGNED: represents an UNSIGNED number
-- : in vector form
-- : -- > UNRESOLVED_SIGNED: represents a SIGNED number
-- : in vector form
-- : The base element type is type STD_ULOGIC.
-- : Aliases U_UNSIGNED and U_SIGNED are defined for the types
-- : UNRESOLVED_UNSIGNED and UNRESOLVED_SIGNED, respectively.
-- : Two numeric subtypes are defined:
-- : -- > UNSIGNED: represents UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The element subtypes are the same subtype as STD_LOGIC.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array
-- : is returned (exceptions, if any, are noted individually).
--
-- Note : This package may be modified to include additional data
-- : required by tools, but it must in no way change the
-- : external interfaces or simulation behavior of the
-- : description. It is permissible to add comments and/or
-- : attributes to the package declarations, but not to change
-- : or delete any original lines of the package declaration.
-- : The package body may be changed only in accordance with
-- : the terms of Clause 16 of this standard.

-- Title : Standard VHDL Synthesis Packages
-- : (NUMERIC_STD package declaration)
-- :
-- Library : This package shall be compiled into a library
-- : symbolically named IEEE.
-- :
-- Developers: IEEE DASC Synthesis Working Group,
-- : Accellera VHDL-TC, and IEEE P1076 Working Group
-- :
-- Purpose : This package defines numeric types and arithmetic functions
-- : for use with synthesis tools. Two numeric types are defined:
-- : -- > UNRESOLVED_UNSIGNED: represents an UNSIGNED number
-- : in vector form
-- : -- > UNRESOLVED_SIGNED: represents a SIGNED number
-- : in vector form
-- : The base element type is type STD_ULOGIC.
-- : Aliases U_UNSIGNED and U_SIGNED are defined for the types
-- : UNRESOLVED_UNSIGNED and UNRESOLVED_SIGNED, respectively.
-- : Two numeric subtypes are defined:
-- : -- > UNSIGNED: represents UNSIGNED number in vector form
-- : -- > SIGNED: represents a SIGNED number in vector form
-- : The element subtypes are the same subtype as STD_LOGIC.
-- : The leftmost bit is treated as the most significant bit.
-- : Signed vectors are represented in two's complement form.
-- : This package contains overloaded arithmetic operators on
-- : the SIGNED and UNSIGNED types. The package also contains
-- : useful type conversions functions, clock detection
-- : functions, and other utility functions.
-- :
-- : If any argument to a function is a null array, a null array
-- : is returned (exceptions, if any, are noted individually).
--
-- Note : This package may be modified to include additional data
-- : required by tools, but it must in no way change the
-- : external interfaces or simulation behavior of the
-- : description. It is permissible to add comments and/or
-- : attributes to the package declarations, but not to change
-- : or delete any original lines of the package declaration.
-- : The package body may be changed only in accordance with
-- : the terms of Clause 16 of this standard.

-- Description: This implementation makes use of the RAMX1 properties,
-- implementing a 16-deep synchronous stack in only one LUT per
-- bit. The value to be popped is always visible.
--
-- For building on altera, this block has been sub-optimized,
-- and the required cells are now inferred.

-- External bus
------------------------------------------------
-- 22/4/2019
--
-- I'm not happy with the design of the external bus interface, for the
-- following reasons:
--
-- 1. extern_we and extern_ce are mediated by the pluggable RAMROM modules
-- in AtomFpga_Core. This means they are not active when external devices
-- in Bxxx are accessed.
--
-- 2. As a work around, I've exposed the 6502 RNW (rnw) signal directly,
-- which is probably the right thing to do, as Atom2K18 does have a full
-- external bus. But it's now confusing as to when to use extern_we and
-- when to use rnw.
--
-- 3. It's not clear how addresses on extern_a correspond to what the CPU
-- accessed, again because this signal is the output of a RAMROM module.
--
-- 4. It seemed wrong to have to add ExternTube and ExternVIA signals to the
-- AtomFpga_Core. It should have been possible to implement these externally
-- in the FPGA target specific wrapper. But (3) made this difficult.
--
-- 5. The NRDS and NWDS signals are currently generated from the RAMROM
-- specific extern_ce and extern_we. It would be better if they uses
-- rnw and ignored extern_ce. But this is more dangerous, so lets
-- see how the current version works before breaking things more!
--
-- What's in place currently will work (I think) for the VIA and Tube, but
-- will not currently allow any devices to be added to the bus. Need to
-- talk with Roland about how he thinks the external bus should be mapped
-- into the Atom address space.
--
-- 22/4/2019
--
-- Roland's reply:
--
-- All addresses from #B000 - #BFFF should be external except for:
-- #B000 - #B003 (8255)
-- #B400 - #B403 (AtoMMC)
-- #B800 - #B80F (6522)
-- #BD00 - #BDFF (Godil + reserved address space)
-- #BFF0 - #BFFF (control registers, some addresses are reserved)
--
-- 23/4/2019
--
-- For consistency, I ended up using a minimum of 16-byte blocks.
-- This is all implemented in AtomFpga_Core
--
-- To answer my concerns above
-- 1. This is resolved by adding a seperate ExternBus output from the core
-- 2. I'm happy exposing RNW directly
-- 3. The RamRom modules should just output the CPU address when not selected
-- 4. ExternVia and ExternTube replaced with ExternBus
-- 5. Use ExternCE/ExternWE (for RamRom) and ExternBus/rnw (for Bus)

-- User interface write data buffer. Consists of four counters,
-- a pointer RAM and the write data storage RAM.
--
-- All RAMs are implemented with distributed RAM.
--
-- Whe ordering is set to STRICT or NORM, data moves through
-- the write data buffer in strictly FIFO order. In RELAXED
-- mode, data may be retired from the write data RAM in any
-- order relative to the input order. This implementation
-- supports all ordering modes.
--
-- The pointer RAM stores a list of pointers to the write data storage RAM.
-- This is a list of vacant entries. As data is written into the RAM, a
-- pointer is pulled from the pointer RAM and used to index the write
-- operation. In a semi autonomously manner, pointers are also pulled, in
-- the same order, and provided to the command port as the data_buf_addr.
--
-- When the MC reads data from the write data buffer, it uses the
-- data_buf_addr provided with the command to extract the data from the
-- write data buffer. It also writes this pointer into the end
-- of the pointer RAM.
--
-- The occupancy counter keeps track of how many entries are valid
-- in the write data storage RAM. app_wdf_rdy and app_rdy will be
-- de-asserted when there is no more storage in the write data buffer.
--
-- Three sequentially incrementing counters/indexes are used to maintain
-- and use the contents of the pointer RAM.
--
-- The write buffer write data address index generates the pointer
-- used to extract the write data address from the pointer RAM. It
-- is incremented with each buffer write. The counter is actually one
-- ahead of the current write address so that the actual data buffer
-- write address can be registered to give a full state to propagate to
-- the write data distributed RAMs.
--
-- The data_buf_addr counter is used to extract the data_buf_addr for
-- the command port. It is incremented as each command is written
-- into the MC.
--
-- The read data index points to the end of the list of free
-- buffers. When the MC fetches data from the write data buffer, it
-- provides the buffer address. The buffer address is used to fetch
-- the data, but is also written into the pointer at the location indicated
-- by the read data index.
--
-- Enter and exiting a buffer full condition generates corner cases. Upon
-- entering a full condition, incrementing the write buffer write data
-- address index must be inhibited. When exiting the full condition,
-- the just arrived pointer must propagate through the pointer RAM, then
-- indexed by the current value of the write buffer write data
-- address counter, the value is registered in the write buffer write
-- data address register, then the counter can be advanced.
--
-- The pointer RAM must be initialized with valid data after reset. This is
-- accomplished by stepping through each pointer RAM entry and writing
-- the locations address into the pointer RAM. For the FIFO modes, this means
-- that buffer address will always proceed in a sequential order. In the
-- RELAXED mode, the original write traversal will be in sequential
-- order, but once the MC begins to retire out of order, the entries in
-- the pointer RAM will become randomized. The ui_rd_data module provides
-- the control information for the initialization process.

-- Be explicit about the latch enable on these registers.

-- rd_data_cnt is the pointer RAM index for data read from the write data
-- buffer. Ie, its the data on its way out to the DRAM.
-- data_buf_addr_cnt generates the pointer for the pointer RAM on behalf

-- Entity: div32
-- File: div32.vhd
-- Author: Jiri Gaisler - Gaisler Research
-- Description: This unit implemets a divide unit to execute 64-bit by 32-bit
-- division. The divider leaves no remainder.
-- Overflow detection is performed according to the
-- SPARC V8 manual, method B (page 116)
-- Division is made using the non-restoring algorithm,
-- and takes 36 clocks. The operands must be stable during
-- the calculations. The result is available one clock after
-- the ready signal is asserted.
