So to get - * maximum performance out of it, you have to treat it as an in-order - * machine. Which means interleaving the computation round t with the - * computation of W[t+4]. - * - * The first 16 rounds use W values loaded directly from memory, while the - * remaining 64 use values computed from those first 16. We preload - * 4 values before starting, so there are three kinds of rounds: - * - The first 12 (all f0) also load the W values from memory. - * - The next 64 compute W(i+4) in parallel. 8*f0, 20*f1, 20*f2, 16*f1. - * - The last 4 (all f1) do not do anything with W. - * - * Therefore, we have 6 different round functions: - * STEPD0_LOAD(t,s) - Perform round t and load W(s). s < 16 - * STEPD0_UPDATE(t,s) - Perform round t and compute W(s). s >= 16. - * STEPD1_UPDATE(t,s) - * STEPD2_UPDATE(t,s) - * STEPD1(t) - Perform round t with no load or update. - * - * The G5 is more fully out-of-order, and can find the parallelism - * by itself. The big limit is that it has a 2-cycle ALU latency, so - * even though it's 2-way, the code has to be scheduled as if it's - * 4-way, which can be a limit. To help it, we try to schedule the - * read of RA(t) as late as possible so it doesn't stall waiting for - * the previous round's RE(t-1), and we try to rotate RB(t) as early - * as possible while reading RC(t) (= RB(t-1)) as late as possible. - */ - -/* the initial loads. */ -#define LOADW(s) \ - lwz W(s),(s)*4(%r4) - -/* - * Perform a step with F0, and load W(s).
