# retroDE_ps2 — Ch336 >FIFO_DEPTH FRAMEBUFFER ACCUMULATION silicon proof.
|
|
#
|
|
# A 14-primitive scene (FIFO depth is 8) renders in TWO batches that COMPOSE into one framebuffer
|
|
# instead of wiping each other (the pre-Ch336 behavior):
|
|
# batch 0 (prims 0-7, tiles 0-7) = RED (clears + full-flushes the framebuffer)
|
|
# batch 1 (prims 8-13, tiles 8-13) = BLUE (sparse-flushes only its pixels onto the accumulated FB)
|
|
# PROOF: the RED top-half AND the BLUE bottom-rows are simultaneously visible at the end. If batches
|
|
# wiped each other, the RED tiles (0-7) would be green. v1 = color accumulation, per-batch Z
|
|
# (shapes are tile-separated, so per-batch Z is honest). records = 14.
|
|
#
|
|
# REQUIRES the Ch336 bitstream (TILE_ACCUM_ENABLE) — a re-fit from Ch335.
|
|
# Register map identical to ps2_feeder_test.sh (BASE 0x40000000).
