Two technologies meet to deliver highly flexible embedded processing solutions: Soft processors in an FPGA can be highly customised for optimal performance in specific applications

摘要

MATCHING THE development speed of writing software for a microprocessor with the hardware flexibility and integration capability offered by FPGAs is a compelling proposition Building soft processors in FPGAs gives developers a unique opportunity to specify exactly the type of processor and peripheral mix that they need, but can't typically find in a catalogue For example, finding a processor with 16 UARTS and 10 discrete, 8-bit PIO ports in a catalogue is very difficult, but building such a system in today's FPGAs is incredibly simple Even the task of creating the hardware is performed by system development tools, These system connectivity tools allow the customisation and choice of processor and peripherals to be done in an intuitive, graphical environment that also updates the software design environment to reflect the automatically generated hardware.
