Loom, Compiler for Fabric

Loom is a full-stack compiler and architecture-exploration framework for multi-core heterogeneous spatial accelerators. It accepts software through an LLVM IR boundary, initially from C and C++ via loom-cc and loom-c++, and hardware as Fabric MLIR produced by the typed C++ ADG Builder, a built-in target, or an imported design.

Loom connects structured compiler optimization, canonical Dataflow programs, Tech/Spatial/System Mapping, multi-fidelity evaluation and simulation, configuration generation, and RTL/EDA implementation. Its target machine is a system of heterogeneous AccCores, each combining an InstructionCore with an arbitrary-topology CGRA SpatialCore.

Documentation

Start with the design documentation. The full-stack architecture defines the product and links to the normative subsystem specifications. The architecture rationales explain the decisions behind those contracts without duplicating their authority.
