ORCA-SOFTWARE

ORCA-SOFTWARE is a set of software artifacts that serves as basis for the development of applications for the ORCA MPSOC. This repository includes a copy of the HellfireOS, examples applications, and other integration tools.

• HellfireOS. This repository has a copy of the HellfireOS, a fully-preemptive real-time operating system.
• Applications. Several applications are provided in the software folder.
• Extensions. Some extensions to permit using hardware monitors and counters, the publish-subscribe communication model, and static task mapping.
• Tools. Provide integration tools for off-chip communication and integration with the ROS system.

Related repositories are enlisted below.

• ORCA-MPSOC: https://github.com/andersondomingues/orca-mpsoc
• ORCA-SIM: https://github.com/andersondomingues/orca-sim

Quick Start

1. Clone this repository
2. Go to the root folder and type $make in the terminal (Make and RiscV toolchain required!)
3. The generated image.bin will be available in the bin folder.

Project organization

• /bin : compiled binaries and compilation artifacts
• /docs : tutorials and guidance resources
• /logs : output logs for each individual processor core
• /models : hardware models (processor core, memory cores, etc.)
• /platforms : top-level platform models (for both many-core and single-core platforms)
• /simulator : URSA's core
• Makefile : Make's script. Do not modifiy it unless you know make language well.
• Configuration.mk : Change this script to reflect the intended project configuration (comments on the parameters are inside the file)

Project Roadmap

Things that we are likely to work on in the next months:

• Provide an API to use for energy evaluation of applications
• Unit tests on software (mainly for HellfireOS, see (https://github.com/andersondomingues/hellfireos)
• Support for C++ apps
• Rework task mapping and wiring (code can be cumbersome when dealing with a large number of signals)
• Provide some IDE-specific projects (hopefully they won't inject any dirt in the project)
• Stub code generator
• Update HellfireOS to match a more stable and recent branch (see (https://github.com/sjohann81/hellfireos)
• DOOM (see https://github.com/lcq2/risc-666)
• Decent tutorials
