# retroDE_ps2 — Ch334 NATIVE RECTANGLE RECORD silicon proof (host command compression).
|
|
#
|
|
# A native rectangle is ONE 3-word record (color + 2 corners) that the FEEDER expands into two
|
|
# colored triangles — 6x smaller host payload than the explicit 18-word two-triangle form, same
|
|
# rendered result. The count word now carries {rect_count[31:16], tri_count[15:0]}. Two scenes:
|
|
# NATIVE_RECT : 3 native rects -> red/green/blue filled quads {0,5,10} (records=6, == Ch333 color_rect)
|
|
# NATIVE_MIX : red triangle(0) + green/blue/yellow native rects(5/10/15) (records=7)
|
|
# Ends on NATIVE_MIX. Sim proof: tb_top_psmct32_feeder_native_demo (matches the explicit version).
|
|
#
|
|
# REQUIRES the Ch334 bitstream (feeder rect-expansion) — a re-fit from Ch333.
|
|
# Register map identical to ps2_feeder_test.sh (BASE 0x40000000).
