Instruction restrictions
|
|
|
|
* The last three instructions of any program (Thread End plus the following two delay-slot instructions) must
|
|
not do varyings read, uniforms read or any kind of VPM, VDR, or VDW read or write.
|
|
* The Program End instruction must not write to either physical regfile A or B.
|
|
* The Program End instruction and the following two delay slot instructions must not write or read address 14
|
|
in either regfile A or B.
|
|
* The final program instruction (the second delay slot instruction) must not do a TLB Z write.
|
|
* A scoreboard wait must not occur in the first two instructions of a fragment shader. This is either the
|
|
explicit Wait for Scoreboard signal or an implicit wait with the first tile-buffer read or write instruction.
|
|
* If TMU_NOSWAP is written, the write must be three instructions before the first TMU write instruction.
|
|
For example, if TMU_NOSWAP is written in the first shader instruction, the first TMU write cannot occur
|
|
before the 4th shader instruction.
|
|
* An instruction must not read from a location in physical regfile A or B that was written to by the previous
|
|
instruction.
|
|
* After an SFU lookup instruction, accumulator r4 must not be read in the following two instructions. Any
|
|
other instruction that results in r4 being written (that is, TMU read, TLB read, SFU lookup) cannot occur in
|
|
the two instructions following an SFU lookup.
|
|
* An instruction that does a vector rotate by r5 must not immediately follow an instruction that writes to r5.
|
|
* An instruction that does a vector rotate must not immediately follow an instruction that writes to the
|
|
accumulator that is being rotated.
|
|
* After an instruction that does a TLB Z write, the multisample mask must not be read as an instruction
|
|
input argument in the following two instruction. The TLB Z write instruction can, however, be followed
|
|
immediately by a TLB color write.
|
|
* A single instruction can only perform a maximum of one of the following closely coupled peripheral
|
|
accesses in a single instruction: TMU write, TMU read, TLB write, TLB read, TLB combined color read and
|
|
write, SFU write, Mutex read or Semaphore access.

==================================================================
|
|
================How to formulate instructions:====================
|
|
==================================================================
|
|
1)
|
|
You must specify the signal bits at the beginning of each instruction:
|
|
sig_brk, sig_none, sig_switch, sig_end, sig_wait_score, sig_unlock_score, sig_thread_switch, sig_coverage_load,
|
|
sig_color_load, sig_color_load_end, sig_load_tmu0, sig_load_tmu1, sig_alpha_mask_load, sig_small_imm, sig_load_imm, sig_branch
|
|
|
|
2)
|
|
Then you must specify the output register for the ADD pipeline.
|
|
rx0-31, r0-3, r5, tmu_noswap, host_int, nop, uniforms_addr, quad_x, quad_y, ms_flags, rev_flags, tlb_stencil_setup
|
|
tlb_z, tlb_color_ms, tlb_color_all, vpm, vr_setup, vr_addr, mutex_release, sfu_recip, sfu_recipsqrt, sfu_exp,
|
|
sfu_log, tmu0_s, tmu0_t, tmu0_r, tmu0_b, tmu1_s, tmu1_t, tmu1_r, tmu1_b
|
|
|
|
3)
|
|
If the ADD instruction writes to regfile A (ie. you don't specify the WS flag later) and PM flag won't be specified,
|
|
then you can specify the pack mode for regfile A here (omitting means nop)
|
|
nop, 16a, 16b, 8888, 8a, 8b, 8c, 8d, sta, 16a.sat, 16b.sat, 8888.sat, 8a.sat, 8b.sat, 8c.sat, 8d.sat
|
|
|
|
4)
|
|
Then you must specify your operation for the ADD pipeline. If you are writing a non-ALU instruction, you can specify either
|
|
branch, sem_inc, sem_dec, load32 or load16 here instead.
|
|
Operations available:
|
|
nop, fadd, fsub, fmin, fmax, fminabs, fmaxabs, ftoi, itof, add, sub, shr, asr, ror, shl, min, max, and, or, xor, not, clz, v8adds, v8subs
|
|
|
|
5)
|
|
Then you can specify a range of modifiers (order is not important):
|
|
PM bit: pm
|
|
SF bit: sf
|
|
WS bit: ws
|
|
REL bit: rel
|
|
REG bit: reg
|
|
SIGNED bit: signed
|
|
Conditional execution for the ADD pipeline (default is never): never, always, zs, zc, ns, nc, cs, cc
|
|
Unpack modes (from regfile A, or if PM is set from R4): nop, 16a, 16b, 8d_rep, 8a, 8b, 8c, 8d
|
|
|
|
6)
|
|
Then you must specify the arguments for the ALU operation.
|
|
srcA, srcB can be: r0-r5 or a, b for regfiles A and B, or imm for the small immediate value.
|
|
raddr_a and raddr_b can be specified afterwards as optional extra arguments (omitting means nop).
|
|
raddr_a: ra0-31, pay_zw, uni, vary, elem, nop, x_pix, ms_flags, vpm_read, vpm_ld_busy, vpm_ld_wait, mutex_acq
|
|
raddr_b: rb0-31, pay_zw, uni, vary, elem, nop, y_pix, rev_flag, vpm_read, vpm_st_busy, vpm_st_wait, mutex_acq
|
|
|
|
For branch operation, you must specify:
|
|
the jump address as a 32bit value (can be relative if REL is set)
|
|
the branch condition: all_zs, all_zc, any_zs, any_zc, all_ns, all_nc, any_ns, any_nc, all_cs, all_cc, any_cs, any_cc, always
|
|
and an optional raddr_a (if REG flag is set), see above
|
|
|
|
For a semaphore instruction, you need to specify which semaphore (0-15) you want to modify, then an optional 27bit immediate value (ms 16bits might be usable...).
|
|
|
|
7)
|
|
Then you must specify the output register for the MUL pipeline.
|
|
See above for options.
|
|
|
|
8)
|
|
If the MUL instruction writes to regfile A (ie. you specify the WS flag) then you can set the pack operation for regfile A here:
|
|
nop, 16a, 16b, 8888, 8a, 8b, 8c, 8d, sta, 16a.sat, 16b.sat, 8888.sat, 8a.sat, 8b.sat, 8c.sat, 8d.sat
|
|
OR
|
|
You if specify the PM flag, then you can set the pack operation for the MUL output here:
|
|
nop, 8888, 8a, 8b, 8c, 8d
|
|
|
|
9)
|
|
Then you must specify your operation for the MUL pipeline. If you are writing a non-ALU instruction, you can specify either
|
|
branch, sem_inc, sem_dec, load32 or load16 here instead.
|
|
Operations available:
|
|
nop, fmul, mul24, v8muld, v8min, v8max, v8adds, v8subs
|
|
|
|
10)
|
|
Then you can specify a range of modifiers (order is not important):
|
|
Conditional execution for the MUL pipeline: never, always, zs, zc, ns, nc, cs, cc
|
|
|
|
11)
|
|
Then you must specify the arguments for the ALU operation.
|
|
srcA, srcB can be: r0-r5 or a, b for regfiles A and B, or imm for the small immediate value.
|
|

|
|
sig_none ; rx0.nop = sem_inc.pm.sf.always(1, 0x7ffffff) ; rx0.nop = sem_inc.always() ;
|
|
sig_load_imm ; rx0.nop = load32.pm.sf.always(0xdeadbeef) ; rx0.nop = load32.always() ;
|
|
sig_load_imm ; rx0.nop = load16.pm.sf.signed.always(1, 2) ; rx0.nop = load16.always() ;

#mov

sig_none ; rx0.nop = or(r0, r0) ; rx0 = v8min(r1, r1) ;
