Recommendations for learning and getting hands-on Real Time Signal processing
I had taken the course at my university. So most of the materials were provided as part of it. I worked with 2 different DSPs both of which were provided at the lab.
If you are looking to buy hardware, Real-Time Digital Signal Processing by Sen M Kuo and Bob H Lee is a good book with implementation and architecture descriptions of TMS320C55x. It has around 9 interesting application-level implementations as well. But getting all the hardware necessary might be too much though.
