Overview
The program sends 8192 bytes of random data to VRAM through DMA channel 2 after a GP0(A0h) copy command, and times each transfer in CPU cycles from the CHCR write until the channel goes idle. It first uses sync mode 1 with block sizes from 1 to 64 words and 128 words. It then uses sync mode 0 without chopping. Last it uses sync mode 0 with chopping at every pair of DMA window (1 to 128 words) and CPU window (1 to 128 clocks).1 After each transfer the program reads GPUSTAT bit 26 and prints "(GPU busy)" when the GPU was not yet ready for a command.1
Results
In sync mode 1 the transfer took 22,866 cycles with 1-word blocks and fell as the blocks grew: 12,550 with 2-word blocks, 4,756 with 8, 3,555 with 16, 2,971 with 32 and 2,527 with 128. Sync mode 0 without chopping took 2,245 cycles. No other transfer was shorter.2
With chopping in sync mode 0, the DMA window sets the words moved in each turn and the CPU window the clocks given back to the CPU between turns. The times of the run of 25 September 2026 were as follows:2
| DMA window (words) | CPU 1 | CPU 2 | CPU 4 | CPU 8 | CPU 16 | CPU 32 | CPU 64 | CPU 128 |
|---|---|---|---|---|---|---|---|---|
| 1 | 18,797 | 18,795 | 22,863 | 30,899 | 47,731 | 80,696 | 81,931 | 80,045 |
| 2 | 9,438 | 10,551 | 12,548 | 16,450 | 24,638 | 41,008 | 73,755 | 73,677 |
| 4 | 5,782 | 6,320 | 7,351 | 9,422 | 13,430 | 21,860 | 37,952 | 70,681 |
| 8 | 3,984 | 4,242 | 4,755 | 5,758 | 7,772 | 11,960 | 20,160 | 36,351 |
| 16 | 3,054 | 3,243 | 3,471 | 4,010 | 4,998 | 7,034 | 11,048 | 19,226 |
| 32 | 2,676 | 2,766 | 2,810 | 3,124 | 3,630 | 4,634 | 6,596 | 10,748 |
| 64 | 2,464 | 2,500 | 2,560 | 2,680 | 2,908 | 3,418 | 4,400 | 6,420 |
| 128 | 2,338 | 2,362 | 2,390 | 2,470 | 2,580 | 2,780 | 3,304 | 4,199 |
With a 1-word DMA window the time stopped growing at about 80,000 cycles once the CPU window reached 32 clocks. With a 2-word window it stopped at about 73,700 cycles from 64 clocks on.2
The six runs agreed to within 0.5% on the small figures. The sync mode 0 transfer without chopping took 2,242 to 2,252 cycles and the 1-word block transfer 22,860 to 22,866 cycles. The 128-word, 128-clock transfer took 4,199 to 4,242 cycles.2
