PRUs to offload processing of raw data

The idea is to be able to access on-board peripherals like the McSPI, McASP etc from the PRUs and to be able to use fetch data directly from these peripherals. This will allow to offload processing of the Raw data onto the PRUs. The project will basically involve developing C libraries for the PRUs to connect to these peripherals, developing DT overlays for the peripherals to be used and developing Drivers to reserver the device on behalf of the PRUs.

Status

This project is currently just a proposal.


Proposal

I cross-complied "Hello world" application and generated a pull request as per requirement. Apart from this to prove my ability I made programs on DToverlay for LED on off using switch, simple Loadable Kernel Module (LKM) and LED blinking using PRU. I have successfully tested code on BeagleBone Black. Currently I am learning more advance concept which can help me in this project.

Previous GSoC participation: I am participating first time in GSoC.

I am hobbyist and love to play with embedded systems. Normally I used AVR microcontroller for my projects but as project grows I need more powerfully platform and I that's how I found beagle-bone. I used BBB as server in my current semester project of Generic ZigBee stack simulation. I am vary impressed with capabilities & performance of this board . It will be honer for me to contribute in such great community. GSoC project will not only help me to improve my knowledge but this is a kind of project which will definitely help community and add more capability in BeagleBone .

About your project

Project name: PRUs to offload processing of raw data from on-board Peripherals

Description

PRUs stands for Programmable Real-time Units it is low‐latency microcontroller subsystem. There are two independent PRU execution units with features like 32‐Bit RISC architecture, 200Mhz single cycle execution,no pipeline, interrupt Controller ,fast I/O interface. This makes PRU best choice for real time processing task in board like BeagleBone which have Linux OS running on it.

The goal of this project is to be able to access on-board peripherals and allow to offload processing of the Raw data. The main part in project is to develop C libraries for the PRUs to connect to on-board peripherals. This will reduce load on main processor and enhance performance of device.
