/*
* Register info
*
* 0. "-"
* size: 16
* desc: Constant register with all bits set (0xffff).
*
* 1. "X"
* size: 16
* desc: Generic register. When set, updates P (P = X * Y * 2)
*
* 2. "Y"
* size: 16
* desc: Generic register. When set, updates P (P = X * Y * 2)
*
* 3. "A"
* size: 32
* desc: Accumulator.
*
* 4. "ST"
* size: 16
* desc: Status register. From MAME: bits 0-9 are CONTROL, other FLAG
* fedc ba98 7654 3210
* 210 - RPL (?) "Loop size". If non-zero, makes (rX+) and (rX-) respectively
* modulo-increment and modulo-decrement. The value shows which
* power of 2 to use, i.e. 4 means modulo by 16.
* (e: fir16_32.sc, IIR_4B.SC, DECIM.SC)
* 43 - RB (?)
* 5 - GP0_0 (ST5?) Changed before acessing PM0 (affects banking?).
* 6 - GP0_1 (ST6?) Cleared before acessing PM0 (affects banking?). Set after.
* datasheet says these (5,6) bits correspond to hardware pins.
* 7 - IE (?) Not directly used by SVP code (never set, but preserved)?
* 8 - OP (?) Not used by SVP code (only cleared)? (MAME: saturated value
* (probably means clamping? i.e. 0x7ffc + 9 -> 0x7fff))
* 9 - MACS (?) Not used by SVP code (only cleared)? (e: "mac shift")
* a - GPI_0 Interrupt 0 enable/status?
* b - GPI_1 Interrupt 1 enable/status?
* c - L L flag. Carry?
* d - Z Zero flag.
* e - OV Overflow flag.
* f - N Negative flag.
* seen directly changing code sequences:
* ldi ST, 0 ld A, ST ld A, ST ld A, ST ldi st, 20h
* ldi ST, 60h ori A, 60h and A, E8h and A, E8h
* ld ST, A ld ST, A ori 3
* ld ST, A
*
* 5. "STACK"
* size: 16
* desc: hw stack of 6 levels (according to datasheet)
*
* 6. "PC"
* size: 16
* desc: Program counter.
*
* 7. "P"
* size: 32
* desc: multiply result register. P = X * Y * 2
* probably affected by MACS bit in ST.
*
* 8. "PM0" (PM from PMAR name from Tasco's docs)
* size: 16?
* desc: Programmable Memory access register.
* On reset, or when one (both?) GP0 bits are clear,
* acts as status for XST, mapped at 015004 at 68k side:
* bit0: ssp has written something to XST (cleared when 015004 is read)
* bit1: 68k has written something through a1500{0|2} (cleared on PM0 read)
*
* 9. "PM1"
* size: 16?
* desc: Programmable Memory access register.
* This reg. is only used as PMAR.
*
* 10. "PM2"
* size: 16?
* desc: Programmable Memory access register.
* This reg. is only used as PMAR.
*
* 11. "XST"
* size: 16?
* desc: eXternal STate. Mapped to a15000 and a15002 at 68k side.
* Can be programmed as PMAR? (only seen in test mode code)
* Affects PM0 when written to?
*
* 12. "PM4"
* size: 16?
* desc: Programmable Memory access register.
* This reg. is only used as PMAR. The most used PMAR by VR.
*
* 13. (unused by VR)
*
* 14. "PMC" (PMC from PMAC name from Tasco's docs)
* size: 32?
* desc: Programmable Memory access Control. Set using 2 16bit writes,
* first address, then mode word. After setting PMAC, PMAR sould
* be blind accessed (ld -, PMx or ld PMx, -) to program it for
* reading and writing respectively.
* Reading the register also shifts it's state (from "waiting for
* address" to "waiting for mode" and back). Reads always return
* address related to last PMx register accressed.
* (note: addresses do not wrap).
*
* 15. "AL"
* size: 16
* desc: Accumulator Low. 16 least significant bits of accumulator.
* (normally reading acc (ld X, A) you get 16 most significant bits).
*
*
* There are 8 8-bit pointer registers rX. r0-r3 (ri) point to RAM0, r4-r7 (rj) point to RAM1.
* They can be accessed directly, or 2 indirection levels can be used [ (rX), ((rX)) ],
* which work similar to * and ** operators in C, only they use different memory banks and
* ((rX)) also does post-increment. First indirection level (rX) accesses RAMx, second accesses
* program memory at address read from (rX), and increments value in (rX).
*
* r0,r1,r2,r4,r5,r6 can be modified [ex: ldi r0, 5].
* 3 modifiers can be applied (optional):
* + : post-increment [ex: ld a, (r0+) ]. Can be made modulo-increment by setting RPL bits in ST.
* - : post-decrement. Can be made modulo-decrement by setting RPL bits in ST (not sure).
* +!: post-increment, unaffected by RPL (probably).
* These are only used on 1st indirection level, so things like [ld a, ((r0+))] and [ld X, r6-]
* ar probably invalid.
*
* r3 and r7 are special and can not be changed (at least Samsung samples and SVP code never do).
* They are fixed to the start of their RAM banks. (They are probably changeable for ssp1605+,
* Samsung's old DSP page claims that).
* 1 of these 4 modifiers must be used (short form direct addressing?):
* |00: RAMx[0] [ex: (r3|00), 0] (based on sample code)
* |01: RAMx[1]
* |10: RAMx[2] ? maybe 10h? accortding to Div_c_dp.sc, 2
* |11: RAMx[3]
*
*
* Instruction notes
*
* ld a, * doesn't affect flags! (e: A_LAW.SC, Div_c_dp.sc)
*
* mld (rj), (ri) [, b]
* operation: A = 0; P = (rj) * (ri)
* notes: based on IIR_4B.SC sample. flags? what is b???
*
* mpya (rj), (ri) [, b]
* name: multiply and add?
* operation: A += P; P = (rj) * (ri)
*
* mpys (rj), (ri), b
* name: multiply and subtract?
* notes: not used by VR code.
*
* mod cond, op
* mod cond, shr does arithmetic shift
*
* 'ld -, AL' and probably 'ld AL, -' are for dummy assigns
*
* memory map:
* 000000 - 1fffff ROM, accessable by both
* 200000 - 2fffff unused?
* 300000 - 31ffff DRAM, both
* 320000 - 38ffff unused?
* 390000 - 3907ff IRAM. can only be accessed by ssp?
* 390000 - 39ffff similar mapping to "cell arrange" in Sega CD, 68k only?
* 3a0000 - 3affff similar mapping to "cell arrange" in Sega CD, a bit different
*
* 30fe02 - 0 if SVP busy, 1 if done (set by SVP, checked and cleared by 68k)
* 30fe06 - also sync related.
* 30fe08 - job number [1-12] for SVP. 0 means no job. Set by 68k, read-cleared by SVP.
*
* + figure out if 'op A, P' is 32bit (nearly sure it is)
* * does mld, mpya load their operands into X and Y?
* * OP simm
*
* Assumptions in this code
* P is not directly writeable
* flags correspond to full 32bit accumulator
* only Z and N status flags are emulated (others unused by SVP)
* modifiers for 'OP a, ri' are ignored (invalid?/not used by SVP)
* 'ld d, (a)' loads from program ROM

CARTRIDGE ROM MIRRORING
***************************************************************************************************************
Cartridge area is mapped to $000000-$3fffff:
-> when accessing ROM, 68k address lines A1 to A21 are used by the internal cartridge hardware to decode the
full 4MB address range.
-> depending on the ROM total size, some address lines might be ignored, resulting in ROM mirroring.
Cartridges can use either 8-bits (x2) or 16-bits (x1, x2) Mask ROM chips, each chip size is a factor of 2 bytes:
-> two 8-bits chips are equivalent to one 16-bits chip, no specific address decoding is required, needed
address lines are simply connected to each chip, upper address lines are ignored and data lines are
connected appropriately to each chip (D0-D7 to one chip, D8-D15 to the other one).
ROM is mirrored each N bytes where N=2^(k+1) is the total ROM size (ROM1+ROM2,ROM1+ROM2,...).
-> one single 16-bits chip do not need specific address decoding, address lines are simply connected
depending on the ROM size, upper address lines being ignored.
ROM is mirrored each N bytes where N=2^k is the size of the ROM chip (ROM1,ROM1,ROM1,...).
-> two 16-bits chips of the same size are equivalent to one chip of double size, address decoding generally
is the same except that specific hardware is used (one address line is generally used for chip selection,
lower ones being used to address the chips and upper ones being ignored).
ROM is mirrored continuously each N bytes where N=2^(k+1) is the total ROM size (ROM1,ROM2,ROM1,ROM2,...).
-> two 16-bits chips with different size are mapped differently. Address decoding is done the same way as
above (one address line used for chip selection) but the ignored & required address lines differ from
one chip to another, which makes ROM mirroring different.
ROM2 size is generally half of ROM1 size and ROM are mirrored like that : ROM1,ROM2,ROM2,ROM1,ROM2,ROM2,...
From the emulator point of view, we only need to distinguish 3 cases:
1/ total ROM size is a factor of 2: ROM is mirrored each 2^k bytes.
2/ total ROM size is not a factor of 2 and cartridge uses one or two chips of the same size (Type A):
ROM is padded up to 2^k and mirrored each 2^k bytes.
3/ total ROM size is not a factor of 2 and cartridge uses two chips of different sizes (Type B):
ROM is not padded and the first 2^(k-1) bytes are mirrored each 2^k bytes while the next 2^(k-2) bytes are
mirrored in the last 2^(k-2) bytes.

FIFO emulation (Chaos Engine/Soldier of Fortune, Double Clutch, Sol Deace)

CPU access per line is limited during active display:
H32: 16 access --> 3420/16 = ~214 Mcycles between access
H40: 18 access --> 3420/18 = ~190 Mcycles between access
This is an approximation, on real hardware, the delay between access is
more likely 16 pixels (128 or 160 Mcycles) with no access allowed during
HBLANK (~860 Mcycles), H40 mode being probably a little more restricted.
Each VRAM access is byte wide, so one VRAM write (word) need twice cycles.
