For hobby projects? Multiple reasons: - because writing RTL is fun, while writing C code is boring. :-) - because it's probably not possible to outputs VGA with your standard microprocessor. You can create a dinky 3-bit VGA output with very little hardware. - because I may want to DMA data from an external sensor and feed it straight into a DSP for processing, and only use the CPU to deal with the post-processed result. Think multi-channel audio etc. - because anything that requires fast real-time is probably not possible with the standard microprocessor. But mostly because writing RTL is fun.
