9th Experiment
This was the first hardware based demo of signal processing. Our senior conducted this for us. The session was conducted using the TMS320F28375 DSP board. Emulation was observed of real time audio input in class demonstration. We learned to perform basic arithmetic functions-
1. Basic Arithmetic operations - ADD,SUB,MUL,DIV.
2. Bitwise operations - AND, NOT
3. Shifting operation - SHIFT LEFT/RIGHT AND ROTATE LEFT/RIGHT
It was concluded that a large number of mathematical operations can be performed and repeatedly on this processor since it is a specialised microprocessor.
We used code composer studio to observe the changes in register values that take place during all operations too.
ReplyDeleteYes.
DeleteThanks for mentioning that.
Much better efficiency using DSP processors
ReplyDeleteYes because of Parallel Processing and dedicated ALU + MAC unit
ReplyDeleteCode composer studio version 3.3 was used to program the DSP processor.
ReplyDeleteThanks for mentioning that.
DeleteJTAG cable was used to interface DSP processor and the computer rather than USBASP cable as JTAG allowed the user to check the values of the register of DSP processor in intermediate stages rather than just at the end which helps in debugging.
ReplyDeleteHe also demonstrated code for speech recognition which is a application of DSP.
