| # SHA256/512_Transform for Itanium. |
| # |
| # sha512_block runs in 1003 cycles on Itanium 2, which is almost 50% |
| # faster than gcc and >60%(!) faster than code generated by HP-UX |
| # compiler (yes, HP-UX is generating slower code, because unlike gcc, |
| # it failed to deploy "shift right pair," 'shrp' instruction, which |
| # substitutes for 64-bit rotate). |
| # |
| # 924 cycles long sha256_block outperforms gcc by over factor of 2(!) |
| # and HP-UX compiler - by >40% (yes, gcc won sha512_block, but lost |
| # this one big time). Note that "formally" 924 is about 100 cycles |
| # too much. I mean it's 64 32-bit rounds vs. 80 virtually identical |
| # 64-bit ones and 1003*64/80 gives 802. Extra cycles, 2 per round, |
| # are spent on extra work to provide for 32-bit rotations. 32-bit |
| # rotations are still handled by 'shrp' instruction and for this |
| # reason lower 32 bits are deposited to upper half of 64-bit register |
| # prior 'shrp' issue. And in order to minimize the amount of such |
| # operations, X[16] values are *maintained* with copies of lower |
| # halves in upper halves, which is why you'll spot such instructions |
| # as custom 'mux2', "parallel 32-bit add," 'padd4' and "parallel |
| # 32-bit unsigned right shift," 'pshr4.u' instructions here. |
| # |
| # Rules of engagement. |
| # |
| # There is only one integer shifter meaning that if I have two rotate, |
| # deposit or extract instructions in adjacent bundles, they shall |
| # split [at run-time if they have to]. But note that variable and |
| # parallel shifts are performed by multi-media ALU and *are* pairable |
| # with rotates [and alike]. On the backside MMALU is rather slow: it |
| # takes 2 extra cycles before the result of integer operation is |
| # available *to* MMALU and 2(*) extra cycles before the result of MM |
| # operation is available "back" *to* integer ALU, not to mention that |
| # MMALU itself has 2 cycles latency. However! I explicitly scheduled |
| # these MM instructions to avoid MM stalls, so that all these extra |
| # latencies get "hidden" in instruction-level parallelism. |
| # |
| # (*) 2 cycles on Itanium 1 and 1 cycle on Itanium 2. But I schedule |
| # for 2 in order to provide for best *overall* performance, |
| # because on Itanium 1 stall on MM result is accompanied by |
| # pipeline flush, which takes 6 cycles:-( |
| # |
| # Resulting performance numbers for 900MHz Itanium 2 system: |
| # |
| # The 'numbers' are in 1000s of bytes per second processed. |
| # type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes |
