Snitch Software

This subdirectory contains the various bits and pieces of software for the Snitch ecosystem.

Contents

Libraries

• applications: Contains applications and kernels, mostly NN-related with SW testbenches for performance profiling.
• cmake: Bits and pieces for integration with the CMake build system.
• snRuntime: The fundamental, bare-metal runtime for Snitch systems. Exposes a minimal API to manage execution of code across the available cores and clusters, query information about a thread's context, and to coordinate and exchange data with other threads. Hardware configuration dependent implementations of the snRuntime can be found, e.g., under target/snitch_cluster/sw/snRuntime.
• snBLAS: A minimal reference implementation of the basic linear algebra subprograms that demonstrates the use of Snitch and its extensions.

Tests

• benchmark: Benchmarking executables that evaluate the performance characteristics of a system.
• test: Unit tests for various aspects of a system, including the instruction set extensions. These complement the library-specific unit tests that live within the library directories proper.

Third-Party

The deps directory contains third-party tools that we inline into this repository for ease of use.

• deps/riscv-opcodes: Utilities to manage instruction encodings and generate functions and data structurse for parsing and representation in various languages.
• deps/printf: A printf / sprintf implementation for embedded systems.
