Overview
The program follows on from Store and Load Sequences. It times a store, a load and a store with each kind of target, the instruction that runs when a RAM load's data arrives, loads and stores from code in KSEG1, loads from each device by width and in pairs, and instruction cache fills at printed addresses. Its timing rows are root counter 2 counts in system clock cycles for 100 turns of a loop body.1
Its GTE groups time single NOP steps on inputs that earlier runs left as ranges. Each of the three vectors of RTPT is timed on its own. Each GTE row runs cold from RAM and then cached.1

Results
The Instruction When a Load Completes
A RAM load followed by six NOPs took 1251 cycles for 100 turns. A seventh instruction adds one cycle a turn when it is a NOP, but one more than that when it is an ALU instruction, a store, a scratchpad load or a multiply. A second RAM load in that place adds about five.1
| Seventh instruction | Cycles |
|---|---|
| nop | 1362 |
| addu | 1454 |
| addu of the loaded register | 1466 |
| mult | 1463 |
| scratchpad lw | 1466 |
| RAM sw | 1488 |
| RAM lw | 1768 |
Stores and Loads by Target
A second RAM store after a store and a load costs about 4 cycles a turn more than a NOP in its place (1870 to 1892 against 1468). The width of the store makes no difference. A scratchpad store in its place costs about 2 (1632).1
A RAM load waits for a store before it only when the store went to RAM or to an I/O port:1
| Store | Load | Cycles |
|---|---|---|
| scratchpad sw | RAM lw | 958 |
| GP0 sw | RAM lw | 1038 |
| I_MASK sw | RAM lw | 1036 |
| RAM sw | I_STAT lw | 958 |
| RAM sw | scratchpad lw | 629 |
| RAM sw | BIOS lw | 3132 |
| RAM sw | RAM lw | 1468 |
Code Run from KSEG1
Each instruction fetched from KSEG1 costs about 6 cycles. The loop alone took 1886 cycles and each NOP added about 610.1
A load or store adds to the fetch time according to its target. An I_STAT load adds nothing beyond its own fetch, and neither do stores to the scratchpad, GP0 or I_MASK. A RAM load adds about 4 cycles a turn and a RAM store about 5. A BIOS ROM load adds about 22.1
| Body | Cycles |

| the loop alone | 1886 |
| 1 nop | 2495 |
| I_STAT lw | 2495 |
| scratchpad sw | 2491 |
| RAM lw | 2905 |
| RAM sw | 3012 |
| RAM sw, sw | 3833 |
| BIOS lw | 4711 |
Loads by Device
Each device has its own load time, and the second of two loads waits for the first:1
| Load | Load, nop | Load, the same, nop | Load, nop, the same, nop |
|---|---|---|---|
| DMA2 CHCR lw | 751 | 1147 | 1346 |
| DICR lw | 750 | 1139 | 1346 |
| MDEC status lw | 750 | 1139 | 1346 |
| Timer 0 lw | 750 | 1139 | 1346 |
| I_STAT lbu | 740 | 1146 | 1353 |
| GPUSTAT lhu | 741 | 1120 | |
| CD-ROM status lbu | 1217 | 2018 | 2218 |
| SPU voice 0 lhu | 2238 | 4218 | |
| SPU voice 0 lbu | 2217 | 4218 | 4218 |
| EXP1 lbu | 1117 | 1822 | 2023 |
| EXP1 lw | 2946 | 5444 | 5645 |
| BIOS lbu | 1117 | 1818 | 2018 |
| BIOS lhu | 1738 | 3018 | |
| Scratchpad lw | 550 | 639 | 746 |
A 32-bit load from expansion region 1 costs as much as a BIOS ROM word load. A byte load from the SPU costs as much as a halfword load.1
Instruction Cache Fills at Known Addresses
With the addresses printed, every cached call repeated its count exactly on a second cached call. A call of four NOPs took 22 counts cold and 7 cached from KSEG0, and 39 from KSEG1.1
GTE Inputs
The three vectors of RTPT take the screen offset OFX at different times. A write of OFX after RTPT reached the first vector's result up to four NOPs after the command, the second's up to four, and the third's up to two in the cold run. In the cached run the limit was six NOPs for the first vector and ten for the other two.1
