bandwidth
Measure GPU/VRAM bandwidth
benchmark
GPU test to benchmark rasterizer for various commands
clut-cache
CLUT (Palette) cache behavior test
clipping
Test Draw Area/Clipping GP0(0xE3), GP0(0xE4) using rectangle and quad
gp0-e1
Check if GP0_E1, GPUSTAT and polygon render uses the same register internally
gpustat
Check GPUSTAT busy bits during rendering in different modes (CPU, linked list DMA, sync block DMA (with GPU DMA direction 1 and 2))
lines
Draws lines using different modes - for verifying Bresenham implementation, color blending, polyline handling
mask-bit
Check Mask bit behavior during VRAM copy operations
quad
Semi-transparent polygon commands - for testing fill rules and transparency handling
rectangles
Draws all combinations of Rectangle commands
texture-flip
Check gp0_e1.13 and gp0_e1.12 texture flip behaviour
texture-overflow
Draws textured rectangle with UV overflowing VRAM width
transparency
Draws rectangles with 4 semi-transparent blending modes
triangle
Draws Gouroud shaded equilateral triangle
uv-interpolate
Check uv/color interpolation accuracy by drawing quads with width in range of 0 - 255
vram-to-vram-overlap
Test GP0(80) VRAM-VRAM copy behaviour in overlapping rects
version-detect
Uses GP1(0x10) and GP0(0xE1) to detect GPU version
GTE
Name
Description
gte-fuzz
Executes GTE opcodes with random parameters, can be used to verify against real console
test-all
Test all register/opcodes, generated by gte-fuzz
MDEC
Name
Description
4bit
♥ Decode single 8x8 block in 4bit mode (sanitized bitstream)
8bit
♥ Decode single 8x8 block in 8bit mode (sanitized bitstream)
frame
Framework for testing MDEC decoder, default values uses DMA for all transfers, but it can be reconfigured for PIO as well (requires manual recompilation). Two executables for 15 and 24bit modes (using DMA for MDECin, MDECout and GPU)
movie
Simple MDEC in-ram bitstream player (currently 200 256x240 frames at @ 10FPS)
step-by-step-log
Manually feeds the MDEC data and monitors the MDEC status register at every step.
SPU
Name
Description
memory-transfer
Test DMA and regular IO transfers to SPU RAM
ram-sandbox
SPU memory access sandbox (used for memory-transfer test development)
stereo
Play samples on first two voices
test
Check SPU behavior (data is lost randomly on 32bit access, ok on 16bit)
toolbox
SPU register preview and simple voice playback tool
Timer
Name
Description
timers
Run Timer0,1,2 using various clock sources and sync modes and time them using busy loops and vblank interrupt
Note: Make sure your PS-EXE loaded does set default value for Stack Pointer - these .exes has SP set to 0.
Tools
Name
Description
diffvram
Diff two images and write diff png if image contents aren't exactly the same
Examples
