Overview
The program follows on from GTE Control Inputs and Store Widths. It times a store, a load and a store in sequence, a store after an I/O load, a load after a store with NOPs between, two loads with NOPs between, and calls that leave an instruction cache line early. Its timing rows are root counter 2 counts in system clock cycles for 100 turns of a loop body.1
Its GTE groups narrow the gaps that earlier runs left as ranges, and a last group reads IR1 back by SWC2 after an MTC2. Each GTE row runs cold from RAM and then cached.1
Results
Two Loads with NOPs between
A second RAM load waits until about five instructions after the first. With one to five NOPs between the two loads the loop took 1679 to 1687 cycles for 100 turns. From the sixth NOP on, each NOP added about a cycle a turn.1
| NOPs between | RAM lw | I_STAT lw | BIOS lw |
|---|---|---|---|
| none, one load only | 960 | 746 | 2943 |
| 0 | 1477 | 1148 | 5447 |
| 1 | 1687 | 1361 | 5658 |
| 3 | 1679 | 1345 | 5644 |
| 5 | 1681 | 1548 | 5643 |
| 8 | 1978 | 5669 | |
| 12 | 2393 | 5667 |
Between two BIOS ROM loads, one to twelve NOPs all gave 5643 to 5669 cycles.1
A Load after a Store
A RAM load after a RAM store waits for the store. With up to five NOPs between them the loop took 1472 to 1491 cycles. With six, seven and eight NOPs it took 1579, 1666 and 1769, so from the sixth NOP each one adds about a cycle a turn.1
Store Load Store
A second RAM store after a store and a load adds about 4 cycles a turn: sw, lw, sw took 1882 cycles against 1473 for sw, lw, NOP. When the first store goes to the GPU's GP0 port the second store adds about 2 (1278 against 1077).1
RAM stores of each width cost the same when no load is near them. One store a turn took 444 to 454 cycles and four stores 888 to 905.1
Instruction Cache Lines Left Early
A call that returns from the first, second or third word of a cache line costs nearly as much cold as one that runs the whole line:1
| Call | Cold | Cached |
|---|---|---|
| jr at word 0 | 26 | 5 |
| jr at word 1 | 26 | 6 |
| jr at word 2 | 25 | 12 |
| 4 nops, then jr (2 lines) | 34 | 14 |
| 8 nops, then jr (3 lines) | 44 | 13 |
SWC2 after MTC2
SWC2 of IR1 stored the old value when it came at once or one NOP after an MTC2 of IR1, and the new value after two NOPs. SWC2 therefore needs the same two-instruction gap as MFC2.1
GTE Inputs Read Late
The program narrowed several inputs that a command reads after it has started:1
| Command | Input | Cold run | Cached run |
|---|---|---|---|
| RTPS | TRX, TRY | none | none |
| RTPS | OFY | not at 4 or more | 5 NOPs after |
| RTPS | DQA | 2 NOPs after | 8 NOPs after |
| RTPS | DQB | 7 NOPs after | |
| NCS | GBK | 1 NOP after | 3 NOPs after |
| MVMVA, V2 | VZ2 | none | 1 NOP after |
| CDP | RGBC | 2 NOPs after |
RTPS reads the translation vector TRX and TRY at its start, and the offset and depth registers OFY, DQA and DQB near its end.1
