@lore I've been looking for reasonably priced DSPs from other countries and yeah the FPGA seems to be the least expensive. It does have built in DSP blocks and whatever it is lacking, it should be able to be implemented in Verilog.
I did get the FPGA for RISC-V work. Perhaps it can work. What kind of specs are you looking for and what features? The DSP along with a RISC arch should be sufficient. I just want to see if it is feasible because the core module is around 20-30 dollars.
@AmpBenzScientist a bit slowly. lost a bit of momentum because i had to wait so long to get the required part. trying to pick up speed on it again beginning this weekend.
