**Hwacha**
A decoupled vector architecture co-processor.
Hwacha currently implements a non-standard RISC-V extension, using a vector architecture programming model.
Hwacha integrates with a Rocket or BOOM core using the RoCC (Rocket Custom Co-processor) interface.
See :ref:`Generators/Hwacha:Hwacha` for more information.
**Gemmini**
A matrix-multiply accelerator targeting neural-networks

The riscv-tools repository was previously required to run any RISC-V software, however, many of the riscv-tools components have since been upstreamed to their respective open-source projects (Linux, GNU, etc.).
Nevertheless, for consistent versioning, as well as software design flexibility for custom hardware, we include the riscv-tools repository and installation in the Chipyard framework.
**esp-tools**
A fork of riscv-tools, designed to work with the Hwacha non-standard RISC-V extension.
This fork can also be used as an example demonstrating how to add additional RoCC accelerators to the ISA-level simulation (Spike) and the higher-level software toolchain (GNU binutils, riscv-opcodes, etc.)
