title: CPU Timing on BIOS DMA2 List Shapes
type: test

## Overview

Root counter 2 counts system clock cycles while the program runs CPU code alone and straight after DMA2 starts a list. Most rows are 100 turns of a short loop run from the instruction cache, and each row runs twice. After a row the program reads which node DMA2 had reached and when the list ended.[^run]

The lists have four shapes. L0 is 1024 empty nodes in forward order, and L1 is an ordering table of 1024 entries in the order ClearOTagR() builds. L2 copies the layout of the list the BIOS sends on frame 399 of its logo. The first node holds no words and the second holds 5. The next 1018 nodes are empty, and the last four hold 8, 0, 6 and 6 words, all of them GP0 NOPs. L3 is L2 with the BIOS's own words: a six word environment node and then a 640 x 480 flat quadrangle at node 1. The last group adds L4, an ordering table of 1024 entries with three 6 word packets of GP0 NOPs, and L5, the same table with three GP0(30h) triangles of about 1, 64 and 4096 pixels.[^run]

## Results

### Loads and Uses

A RAM load whose value is used 7 instructions later in a turn of 10 took about 1,565 cycles alone and 2,339 to 2,353 during L0 or L2. With the use 9 instructions later the list time fell to about 1,900. In a turn of 13 the use at 7 or 9 gave about 2,340 during the list and the use at 12 gave about 2,030. The same rows took 1,857 to 1,887 cycles alone. The three pointer chases took 1,884 to 1,965 cycles alone and 2,589 to 2,595 during either list.[^run]

One RAM load and p NOPs took the same time whether the load came first or last in the turn. During L0 the row stayed near 1,370 cycles from p 5 to p 6. From p 8 on the list time ran 50 to 150 cycles above the alone time.[^run]

Table: Cycles for 100 turns of one RAM load and p NOPs

| p | Alone | During L0 |
| --- | --- | --- |
| 5 | 1,167 | 1,370 |
| 7 | 1,365 | 1,438 |
| 8 | 1,463 | 1,608 |
| 12 | 1,862 | 1,920 |
| 16 | 2,262 | 2,313 |

A DIVU, k NOPs, MFLO and a RAM load took about 4,660 cycles alone at k 0, 2 and 8, and 4,562 to 4,572 during L0 or L2. A MULTU in the same place took about 1,662 alone and 1,597 to 1,625 during the lists. These rows therefore ran about 50 to 100 cycles faster during a list than alone.[^run]

### Stores

Two RAM stores of the same width 40h apart took 570 to 579 cycles alone with no NOP between them, and each NOP added about 100. During L0, L1 or L2 they took 2,743 to 2,756 cycles at every gap from 0 to 6 NOPs, and SB, SH and SW gave the same times. A halfword store followed by a load of the same word took 1,471 to 1,481 cycles alone and 2,703 to 2,716 during a list. A load of a word in another line took 2,653 to 2,659 during a list.[^run]

The RLD rows saved the counter each turn, so the time of every turn is in the output. Alone, most turns took 19 cycles at k 0 and 2, 21 at k 4 and 25 at k 8. During L0 most turns took 35 cycles at every k, and about every seventh turn took 36 to 41 cycles. At k 4 a few pairs of turns read 28 and 48. The totals during L0 were 3,662 to 3,687 cycles for every k.[^run]

Stores to DMA registers, each writing back the value read, took 659 to 664 cycles for 100 turns alone and 1,136 to 1,142 during L0. Loads of D2_MADR and D2_BCR took 859 to 870 alone and 1,168 to 1,173 during L0.[^run]

### Line Fills

Each call in the FLX rows fills the routine's cache lines cold, because the program calls the routine and a twin 4 KB away in turn. A routine of 1 line of NOPs took 1,343 cycles for 100 calls alone and about 1,680 during a list. Each further line added about 900 cycles alone and about 1,530 during a list.[^run]

Table: Cycles for 100 cold calls by line count

| Lines | Alone | During L0, L1 or L2 |
| --- | --- | --- |
| 1 | 1,333 to 1,343 | 1,677 to 1,681 |
| 2 | 2,228 to 2,236 | 3,205 to 3,212 |
| 4 | 4,063 to 4,070 | 6,262 to 6,270 |
| 8 | 7,737 to 7,740 | 12,378 to 12,381 |

Entering a 2 line routine at word 1, 2 or 3 instead of word 0 saved about 100 cycles for each word skipped, alone and during a list. A RAM load as the first word raised the call to 2,618 to 2,639 cycles alone and 4,417 to 4,424 during a list, and a RAM store as the first word to about 2,750 and 4,493 to 4,501. A load at word 2, 3 or 4 cost about 180 cycles less alone than a load at word 0 or 1, but the list time stayed at about 4,420. A call by JR took 2,621 cycles alone and 3,658 to 3,677 during a list. A call by JAL took 2,222 to 2,234 alone and 3,205 to 3,209 during a list.[^run]

On L3 every FLX and SPU row ran within about 15 cycles of its alone time, except the SPU loads with 12 NOPs after each, which took about 95 cycles more. DMA2 stayed at node 2 for the whole row, and the list ended 198,544 to 202,373 cycles after its start. Root counter 1 counted 95 to 98 horizontal blanks over that time.[^run]

### SPU Registers

Four turns of 24 halfword loads from the SPU voice registers took 2,079 cycles alone with no NOPs after each load and about 2,170 with 2 to 12 NOPs. During L0, L1 or L2 the same rows took 2,587 to 2,627 cycles with 0 to 4 NOPs and 2,736 to 2,750 with 12. 100 turns of six SPU halfword stores took about 4,840 cycles alone and 6,245 to 6,257 during a list, whether the stores went to voice 16's registers or to KOFF, KON and EON.[^run]

### BIOS Shell Loops

The shell's loop at 800524DCh, run from ROM for 35 turns, took 1,905 to 1,915 cycles alone. Changing its loads to LW, fixing its addresses or moving its first word to the place it holds in the BIOS left the time unchanged, and removing the uses of its loaded values brought it to 1,513 to 1,559. The loop at 800531ACh took 666 to 684 cycles for 24 turns with its loads on a RAM table, and 980 to 989 with them on the SPU. During a list the SPU version took 1,305 to 1,320 and the RAM version 1,000 to 1,010.[^run]

The byte copy at 800308D0h took 1,386 to 1,404 cycles for 58h bytes. Unrolled by 8 it took about 1,396 alone and about 2,368 during L0.[^run]

### Short Lists

The BST rows store 200 times during lists of 16 nodes. Two byte, halfword or word stores with no NOP between them took 566 to 580 cycles alone. During lists of 16, 64 and 255 word nodes they took about 880, 1,440 and 3,670 cycles, and the list ended at about 1,080, 1,835 and 4,865 cycles.[^run]

Table: Cycles for 512 NOPs during lists of 16 nodes of k words

| k | KSEG1 | Cache |
| --- | --- | --- |
| Alone | 3,167 to 3,175 | 526 |
| 0 | 3,230 | 599 to 603 |
| 16 | 3,448 to 3,453 | 718 to 730 |
| 64 | 4,005 to 4,010 | 1,153 |
| 128 | 4,750 to 4,756 | 1,880 to 1,890 |
| 255 | 6,227 to 6,234 | 3,356 to 3,361 |

### Store Ahead of the List

The SRC rows read DMA2's MADR at node 31 to 33 of the list, then perform one access, then store a link at node m to a side node that ends the list. With m 4 or 8 nodes past the node read, DMA2 had passed node m before the link landed in every row. With m 16 nodes on, DMA2 took the link in every row. The access between the read and the store made no difference: a cold call, a RAM load, an SPU store or 0 to 8 cached NOPs all gave the same result.[^run]

### BIOS Code Path

The RPW group runs the BIOS shell's instruction path through the logo window from a flushed cache. Its loads at 800531CCh go to the SPU as they do in the BIOS. It samples root counter 2 and DMA2's node 17 times along the way, and the path took the same course on L0, L1 and L2. DMA2 reached node 140 at about 1,820 cycles, node 423 at about 5,770 and node 943 at about 12,940, and at about 14,100 cycles the list had ended. Warm, with each part called once before the list starts, the four parts took about 3,155, 3,020, 3,065 and 1,732 cycles on L0 or L1.[^run]

On L3 the cold path ran faster. The 16th of its 17 samples came at 11,307 to 11,332 cycles, against 17,278 to 17,327 on L0, L1 and L2, and DMA2 stayed at node 2 throughout. The list ended at 198,708 to 202,057 cycles, when root counter 1 had counted 124 to 126 horizontal blanks.[^run]

On L4 the path gave the same samples as on L0. The list ended at 17,394 to 17,412 cycles, when root counter 1 had counted 41 or 42 horizontal blanks. On L5 DMA2 was still at node 1021 at 14,104 cycles, and the list ended at 17,380 cycles. With no CPU code but the poll of CHCR2, L4 ended at 10,546 cycles and L5 at 11,006.[^run]
