1 | Note that the UNROLL option makes the 'inner' des loop unroll all 16 rounds |
| 2 | instead of the default 4. | |
| 3 | RISC1 and RISC2 are 2 alternatives for the inner loop and | |
| 4 | PTR means to use pointers arithmatic instead of arrays. | |

| 28 | Notes. | |
| 29 | [1] For the ultra sparc, SunC 4.0 | |
| 30 | cc -xtarget=ultra -xarch=v8plus -Xa -xO5, running 'des_opts' | |
| 31 | gives a speed of 344,000 des/s while 'speed' gives 459,000 des/s. | |
| 32 | I'll record the higher since it is coming from the library but it | |
| 33 | is all rather weird. | |
| 34 | [2] Similar to the ultra sparc ([1]), 181,000 for 'des_opts' vs 175,000. | |
| 35 | [3] I was unable to get access to this machine when it was not heavily loaded. | |
| 36 | As such, my timing program was never able to get more that %30 of the CPU. | |
| 37 | This would cause the program to give much lower speed numbers because | |
| 38 | it would be 'fighting' to stay in the cache with the other CPU burning | |
| 39 | processes. |
