Komorebi PRISM-1 final updated architecture
Projector-Resolved Integrated Signal Machine
PRISM-1 is a packet-programmable mixed-representation processor for Projector-Resolved Seed Calculus and PR-LASM workloads. A program may remain in block, low-rank, Kronecker, sparse-factor, transform, packet-graph, or explicit-array form. The chip preserves the requested output contract rather than an unnecessary dense intermediate.

Design boundary
The package contains a behavioral architecture, a mixed-representation planner, a CUDA-compatible Packet IR, an executable cost model, and RTL boundary modules. It does not contain completed production RTL, synthesis, static timing, place and route, or measured FPGA or silicon performance.
