615 Market-split oracle

615 : Market-split oracle

Design render

How it works

Accumulates row sums as the four input bytes arrive, then compares them with the targets in test/instance.json.

How to test

Write 0x69, 0xc1, 0x3d, 0x34 with SEL = 0, 1, 2, 3, WE high for one clock each. DONE and EXACT_OK go high on the fourth write. An out-of-order write voids the load; restart with SEL = 0.

External hardware

None.
