Acoustic Research Tool (ART)

ART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling. In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported.

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.
