This repository contains the accompanying code to my Bachelor-Thesis 'Parallelizing AES on Raspberry-Pi GPU in Custom Assembly'. It consists of three parts:
Implementation of AES in the Variants 128-bit and 256-bit in ECB mode in custom written Assembly as dictated by the custom GPU Assembler. Each repository contains furthermore comparison implementations of AES, such as tiny-aes or the original rijndael proposal, to which the GPU implementation is compared to in a timing benchmark.
Custom GPU Assembler, that creates binary code from customly defined Syntax, which is extensively documented in my BSc-Thesis. The GPU is a Broadcom VideoCore IV and the Assembler is implemented according to its Architecture Reference Guide. The Custom GPU Assembler was first started by Eric Lorimer and extended upon by Pete Warden. This implementation again extends Pete Warden's implementation and adds multiple convenience and functionality features as well as plenty of in-code documentation.
Example Code to showcase the problems encountered while using more than 192byte of the GPUs Virtual Pipelined Memory (VPM) when using the custom GPU Assembler.
