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 55 # sha1(*) 6210.14k 20376.30k 52447.83k 85870.05k 105478.12k 56 # sha256 7476.45k 20572.05k 41538.34k 56062.29k 62093.18k 57 # sha512 4996.56k 20026.28k 47597.20k 85278.79k 111501.31k 58 # 59 # (*) SHA1 numbers are for HP-UX compiler and are presented purely 60 # for reference purposes.
