Description

Write assembly for the PINC toy ISA to compute a 512-element integer dot product in as few simulated cycles as possible. The pipeline stalls until source registers are ready, with load and multiply instructions taking 5 cycles each. The challenge is scheduling instructions to hide latency through techniques like loop unrolling and interleaving independent operations.
