# retroDE_ps2 — Ch332 SHAPE VOCABULARY silicon proof (triangles + rectangles, runtime-switched).
|
|
#
|
|
# Proves the feeder is no longer triangle-only smoke: a RECTANGLE (filled quad) is expressed as
|
|
# two textured triangles, so the host can command quads on the SAME Ch330/Ch331 path with NO
|
|
# rebuild/reset (and NO new bitstream — this runs on the Ch331 feeder RBF). Three scenes:
|
|
# TRI : 3 half-tile triangles tiles {0,5,10}
|
|
# RECT : 3 filled quads (6 prims) tiles {0,5,10} — same tiles, visibly FULLER
|
|
# MIXED : triangles {0,15} + rects {5,10}
|
|
# Ends on MIXED. Sim proof (tb_top_psmct32_feeder_shapes_demo): tri tile=91 blue px, rect tile=169
|
|
# (full 13x13 quad, no diagonal seam).
|
|
#
|
|
# Register map identical to ps2_feeder_test.sh (BASE 0x40000000). Needs the Ch331 feeder bitstream.
