Pankaj S. Hage, Sanjay B. Pokle · 2014
In the world of social media video processing is very popular. A video signal is the term used to describe any sequence of time varying images. This paper presents the architectures for Video Processing algorithm using softcore processor. This hardware/software co-design platform has been implemented on a Xilinx Virtex-5 FPGA (XUPV5-LX110T). Field Programmable Gate Array (FPGA) offers various resources which can be programmed for building up an efficient embedded system. The system consists of Microblaze and some IP core provided by Xilinx. Soft-core processors are complete microprocessors described in a hardware description language (HDL) such as VHDL, Verilog, etc. Advantages of Softcore Processors are more flexible, Platform independent, high level of abstraction, etc. The aim of this paper is to perform video compressing using discrete wavelet transform (DWT). The DWT was based on time-scale representation, which provides efficient multi-resolution. Video processing applications including video encoding/decoding, surveillance, detection and recognition.
