Reading and Writing to Processor Registers

[vfaraci]

Simtec published a very simple, and in my opinion elegant, C program that reads and writes to processor registers. I believe it was written for ARM processors but it seems to work on my A13 Olinuxino. Below is their website which should prove quite informative on this subject.
