This experiment refreshed the concepts learnt during the Embedded systems course that I had attended during my first year. I had to demonstrate the practical to my batchmates and we executed assembly instructions on the DSP Processor kit available at the laboratory.
Lots of time was spent in designing a High Pass IIR Filter using IIM, but in the end we realized that it was not possible. This was because of the many-to-one mapping of frequencies when using IIM method of filter design.
ReplyDeleteDSP Processors are irreplaceable in many applications.
Nowadays FPGAs are replacing DSPs in some areas like image and speech processing
ReplyDeleteDSPs perform the MAC (multiply-accumulate) instruction with efficiency which is in the core of convolution and execution of calculations for FIR and IIR digital filters. They have also specialized structures to perform discrete Fourier transforms (DFTs) via the FFT algorithm (Fast Fourier Transform), an indispensable operation in almost all applications of DSPs.
ReplyDeleteWhich DSP processor kit is available in your lab?
ReplyDeleteIt's a development board based on the TMS320F28335 DSP processor designed at our college.
ReplyDeleteThe architecture of a DSP processor uses parallel processing features to achieve fast output.
