|
||||
|

; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb. (The
|

; pipeline stalls 2 cycles due to WB contention.)
|
||||
|
||||
; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb. (The
|
||||
; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
|
||||
|
||||
; To enhance speed:
|
||||
; 1. Unroll main loop 4-8 times.
|
||||
; 2. Schedule code to avoid WB contention. It might be tempting to move the
|
||||
; ld instruction in the loops down to save 2 cycles (less WB contention),
|
||||
; but that looses because the ultimate value will be read from outside
|
||||
; the allocated space. But if we handle the ultimate multiplication in
|
||||
; the tail, we can do this.
|
||||
; 3. Make the multiplication with less instructions. I think the code for
|
||||
; (S2_LIMB >= 0x10000) is not minimal.
|
||||
; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
|
||||
; less cycles/limb; the (S2_LIMB < 0x10000) case would run in 11
|

; cycles/limb. (Assuming infinite unrolling.)

; 3. Make the multiplication with less instructions. I think the code for
