GPU State

Measures what GPUSTAT and the GP1(10h) info indices report after each GP0 and GP1 setting and after a GP1(00h) reset.

Overview

The program reads the state of the GPU in two ways: GPUSTAT directly, and the GP1(10h) info indices through GPUREAD. Before each info read it loads GPUREAD with the known word 2BCD1234h by writing two pixels and reading them back with GP0(C0h). An index that does not write GPUREAD therefore shows 2BCD1234h.¹

The groups read every GP1(10h) index and its mirrors (S10), the GP0(E1h) to GP0(E6h) bits as GPUSTAT and the info indices show them (SEB), GPUSTAT after each primitive (STP) and after the GP0 no-operation commands (SGN), the GP1(03h) and GP1(04h) parameters (SDR), the IRQ1 flag (SIR), the GP1(00h) reset (SRS) and 40 display modes (SMD).¹

Results

Indices 02h to 05h return the texture window, drawing area top left, drawing area bottom right and drawing offset. They replace only the bits of their own setting: with GPUREAD holding 2BCD1234h, index 02h returned 2BC5A5A5h for a texture window of 5A5A5h, and index 05h returned 2BD55923h for an offset of 155923h. Index 07h returned 00000002h. Indices 00h, 01h, 06h and 08h to 0Fh returned 00000000h.²

Only the low 4 bits of the index count. Index 12h and the words 10000102h, 1000FF02h and 10FFFFF2h all read the texture window like index 02h, and 17h and 27h read the version like 07h.²

GP1(04h) takes only bits 0 and 1 as the DMA direction. GPUSTAT shows the direction in bits 29 and 30. A parameter of 4 or FFFFFCh gave the same GPUSTAT as 0. GP1(03h) takes only bit 0: a parameter of 2 or FFFFFEh left the display on like 0, and 1 or FFFFFFh turned it off and set GPUSTAT bit 23.³

GP0(1Fh) set GPUSTAT bit 24 and I_STAT bit 1. GP1(01h) left bit 24 set, and GP1(02h) cleared it. A second GP0(1Fh) while bit 24 was still set raised no new I_STAT bit 1. GP0(1Fh) written behind a 1008 x 248 fill set bit 24 at 19,255 cycles, the moment the fill finished.⁴

GP1(00h) left GPUSTAT at 14802000h and cleared indices 02h to 05h to zero. A parameter of FFFFFFh made no difference. After the reset the drawing area is a single pixel at 0,0: a 4 x 4 tile drawn there changed one pixel.⁵
