+simpPRU Basics
+###############
+
+The PRU is a dual core micro-controller system present on the AM335x SoC
+which powers the BeagleBone. It is meant to be used for high speed
+jitter free IO control. Being independent from the linux scheduler and
+having direct access to the IO pins of the BeagleBone Black, the PRU is
+ideal for offloading IO intensive tasks.
+
+Programming the PRU is a uphill task for a beginner, since it involves
+several steps, writing the firmware for the PRU, writing a loader
+program. This can be a easy task for a experienced developer, but it
+keeps many creative developers away. So, I propose to implement a easy
+to understand language for the PRU, hiding away all the low level stuff
+and providing a clean interface to program PRU.
+
+This can be achieved by implementing a language on top of PRU C. It will
+directly compile down to PRU C. This could also be solved by
+implementing a bytecode engine on the PRU, but this will result in waste
+of already limited resources on PRU. With this approach, both PRU cores
+can be run independent of each other.

+What is simpPRU
+---------------
+
+-  simpPRU is a procedural programming language.
+-  It is a statically typed language. Variables and functions must be
+   assigned data types during compilation.
+-  It is typesafe, and data types of variables are decided during
+   compilation.
+-  simpPRU codes have a ``.sim`` extension.
+-  simpPRU provides a console app to use Remoteproc functionality.
