# retroDE_ps2 — Ch331 FEEDER EXPRESSIVENESS silicon proof (variable-size multi-tile scenes).
|
|
#
|
|
# Ch330 proved runtime command ingestion exists (a fixed 4-prim list, repositionable). This proves
|
|
# it SCALES: variable-size HPS-staged scenes rendered in ONE pass via the end-of-list flush, with
|
|
# no rebuild/reset. Streams three scenes of DIFFERENT sizes across the 4x4 tile grid:
|
|
# C1 : 3 prims in tiles {0,5,10} (< the old fixed threshold of 4)
|
|
# C2 : 6 prims in tiles {0,3,5,9,12,15} (> 4 — one pass, NOT split across clears)
|
|
# C3 : 8 prims in tiles {0,1,2,3,12,13,14,15} (== FIFO_DEPTH, the current max scene size)
|
|
# Ends on C3 (top + bottom rows lit) — visibly distinct from the power-up scene.
|
|
#
|
|
# REQUIRES the Ch331 feeder bitstream: ./scripts/select_de25_profile.sh feeder (then re-fit).
|
|
# Register map identical to ps2_feeder_test.sh (BASE 0x40000000):
|
|
# 0x0D8 R ready / W staging addr ; 0x0DC W lo ; 0x0E4 W hi(commit+inc)/R records ; 0x0E8 W go/R waits
