#189851 - FPGA and soft cores Responding to: ???'s previous message |
I've used FPGAs with soft cores, but typically the free ones you get from the FPGA vendor, i.e. Picoblaze and NIOS. The development and debug benefits are substantial if the vendor has tackled all the integration issues. As a purist, I do hanker after a 'hard IP' processor, and the FPGA manufacturers do those as well, notably an ARM core in the Altera Cyclone V. Sometimes infinite flexibility is no great thing, and a few more fixed points in the design are a help.
The only real application for an 8051 core in an FPGA is obsolescence, when you need to run legacy code on new hardware. In that case, as soon as you feel the urge to fire up your debugger, you might as well look at a new 8051 chip anyway. |
