| 10 # SHA256/512_Transform for Itanium. | |
| 11 # | |
| 12 # sha512_block runs in 1003 cycles on Itanium 2, which is almost 50% | |
| 13 # faster than gcc and >60%(!) faster than code generated by HP-UX | |
| 14 # compiler (yes, HP-UX is generating slower code, because unlike gcc, | |
| 15 # it failed to deploy "shift right pair," 'shrp' instruction, which | |
| 16 # substitutes for 64-bit rotate). | |
| 17 # | |
| 18 # 924 cycles long sha256_block outperforms gcc by over factor of 2(!) | |
| 19 # and HP-UX compiler - by >40% (yes, gcc won sha512_block, but lost | |
| 20 # this one big time). Note that "formally" 924 is about 100 cycles | |
| 21 # too much. I mean it's 64 32-bit rounds vs. 80 virtually identical | |
| 22 # 64-bit ones and 1003*64/80 gives 802. Extra cycles, 2 per round, | |
| 23 # are spent on extra work to provide for 32-bit rotations. 32-bit | |
| 24 # rotations are still handled by 'shrp' instruction and for this | |
| 25 # reason lower 32 bits are deposited to upper half of 64-bit register | |
| 26 # prior 'shrp' issue. And in order to minimize the amount of such | |
| 27 # operations, X[16] values are *maintained* with copies of lower | |
| 28 # halves in upper halves, which is why you'll spot such instructions | |
| 29 # as custom 'mux2', "parallel 32-bit add," 'padd4' and "parallel | |
| 30 # 32-bit unsigned right shift," 'pshr4.u' instructions here. | |
| 31 # | |
| 32 # Rules of engagement. | |
| 33 # | |
| 34 # There is only one integer shifter meaning that if I have two rotate, | |
| 35 # deposit or extract instructions in adjacent bundles, they shall | |
| 36 # split [at run-time if they have to]. But note that variable and | |
| 37 # parallel shifts are performed by multi-media ALU and *are* pairable | |
| 38 # with rotates [and alike]. On the backside MMALU is rather slow: it | |
| 39 # takes 2 extra cycles before the result of integer operation is | |
| 40 # available *to* MMALU and 2(*) extra cycles before the result of MM | |
| 41 # operation is available "back" *to* integer ALU, not to mention that | |
| 42 # MMALU itself has 2 cycles latency. However! I explicitly scheduled | |
| 43 # these MM instructions to avoid MM stalls, so that all these extra | |
| 44 # latencies get "hidden" in instruction-level parallelism. | |
| 45 # | |
| 46 # (*) 2 cycles on Itanium 1 and 1 cycle on Itanium 2. But I schedule | |
| 47 # for 2 in order to provide for best *overall* performance, | |
| 48 # because on Itanium 1 stall on MM result is accompanied by | |
| 49 # pipeline flush, which takes 6 cycles:-( | |
| 50 # | |
| 51 # Resulting performance numbers for 900MHz Itanium 2 system: | |
| 52 # | |
| 53 # The 'numbers' are in 1000s of bytes per second processed. | |
| 54 # type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes | |
