Overview
The program follows on from Load Landing and Device Loads. Its first group asks whether the GTE counts the cycles in which the CPU is stalled. Each row writes an input's old value and lets it settle, issues a command, waits, writes the new value and reads the result.1
The wait is a number of NOPs, a divide followed by MFLO, which holds the CPU for about 36 cycles, or a BIOS ROM load and a use of its value. Each row runs from cached code and again from KSEG1, where every instruction fetch stalls the CPU for about 5 cycles.1
The other groups time the instruction that runs as a RAM load completes and loads and stores from code in KSEG1. Their rows are root counter 2 counts in system clock cycles for 100 turns of a loop body.1
Results
The GTE Runs while the CPU Stalls
A GTE command keeps running while the CPU waits. A write that reaches the command from cached code arrives too late when the same instructions run from KSEG1, because the fetches there take more cycles. A divide or a slow load between the command and the write has the same effect.1
| Command and input | Gap | Cached code | KSEG1 code |
|---|---|---|---|
| RTPS, OFX | 0 to 4 NOPs | new | old |
| RTPS, OFX | 6 NOPs | old | old |
| RTPS, OFX | a divide | old | old |
| RTPS, DQB | 4 or 6 NOPs | new | old |
| RTPS, DQB | a divide | old | old |
| NCS, VZ0 | 0 or 1 NOP | new | old |
| NCS, RBK | 0 or 2 NOPs | new | old |
| RTPT, OFX | 4 or 8 NOPs | new | old |
| RTPT, OFX | a divide | old | old |
The same holds for inputs written before a command. A write of TRZ one NOP before RTPS reached the command only from KSEG1, and a divide before RTPS let it reach the command from cached code as well. SQR with IR1 written one NOP before used the new IR1 only from KSEG1.1
The Instruction When a Load Completes
The table gives each instruction placed after a RAM load and five, six or seven NOPs:1
| Instruction | 5 NOPs | 6 NOPs | 7 NOPs |
|---|---|---|---|
| addu | 1362 | 1448 | 1562 |
| RAM lw | 1680 | 1764 | 1887 |
| scratchpad lw | 1331 | 1441 | 1526 |
| I_STAT lw | 1520 | 1620 | 1723 |
| BIOS lw | 3647 | 3721 | 3822 |
| RAM sw | 1478 | 1477 | 1572 |
| scratchpad sw | 1332 | 1440 | 1539 |
| GP0 sw | 1332 | 1439 | 1536 |
Loads and Stores from KSEG1 Code
From KSEG1 a NOP loop took 2497 cycles for 100 turns. A load or store adds to that according to its target and not its width:1
| Body | Cycles |
|---|---|
| 1 nop | 2497 |
| I_STAT, GPUSTAT or scratchpad lw | 2495 |
| RAM lw, lhu or lbu | 2901 to 2907 |
| EXP1 lbu or BIOS lbu | 2900 to 2904 |
| CD-ROM status lbu | 3011 |
| SPUSTAT lhu | 3995 |
| BIOS lw | 4708 |
| RAM sw, sh or sb | 3008 to 3012 |
| GP0 sw, SPU sh, CD-ROM sb, scratchpad sw | 2491 to 2495 |
| RAM sw, sw | 3833 |
| GP0 sw, sw | 3103 |
A store to an I/O port from KSEG1 code adds nothing to the fetch time, and a store to RAM adds about 5 cycles.1
