mshr-h / motion_estimation_processor_4pixsearch

4-pix search based Motion Estimation Processor written in Verilog-HDL

Motion Estimation Processor

Hardware implementation of Motion Estimation algorithm written in Verilog-HDL. It's currently under development.

Description

• Fullsearch based motion estimation
• Double acuracy, integer acucuracy motion estimation
• No fractional motion estimation
• Template Block: 16x16 pixels
• Search Range : ±24 pixels

Required Tools

• Icarus Verilog(>=10.0)
• Altera Quartus Prime(>=16.0)
• Excel 2013
• Golang

How to run Simulation

1. Open memory/memory.xlsx
2. Click 'Create Memory' button to create memory/memory_sw_A.txt, memory/memory_sw_B.txt, memory/memory_sw_C.txt, memory/memory_sw_D.txt for search range memory and memory_tb_A.txt, memory_tb_B.txt, memory_tb_C.txt, memory_tb_D.txt for template block memory
3. Run make_tb.sh
4. You will find the wave file testbench/***.vcd
