Digital Signal Processing (DSP) is applied to the collected time-domain signals to obtain their frequency-domain results. When a signal is transformed from the time domain to the frequency domain, there are specific DSP terminologies, and these terms have important mathematical relationships with each other. Are you clear about them? The following are the DSP terminologies. … Read more
The architecture of traditional Digital Signal Processors (DSP) has become inadequate for specific signal processing computational applications. However, the combination of Very Long Instruction Word (VLIW) and Single Instruction/Multi Data (SIMD) architectures can provide the parallel throughput required for high computational performance, with data typically being 16, 24, and 32 bits wide. This is particularly … Read more
