Learning and Examples

Embedded_Systems_Sobel_Filter__BlockDesign-SDK

Based on a SW version of a Sobel filter written in C, using the Vivado HLS (High Level Synthesis) tool a hardware accelerator is build reducing the function's execution time on an ARM processor to the minimum using various optimizations through code directives. The optimizations are tested individually for their additional performance gains. Software running on a processor, no matter how well optimized it is, is slower than a hardware accelerator implementing the same functionality. Translating the functionality of a computationally intensive function to a HW Description language using all the available advantages HW parallelism and flexibility has to offer can be a really time consuming and often repetitive feat.
