Processor Capabilities - Michael Barrell - Mar 31 10:50:00 2003

Currently at my company we are getting ready to choose a new processor for a new project. Our list is short, but basically it is between the microblaze, nios and a TI chip (320F28x family). My question is what processor would you all choose, and why? Also to note is that the system we are developing is a math intensive, high bandwidth system. Currently we are running two servo systems on the system we have today and at its peak operation we are taking up 70% of the bandwidth on a NEC850 @ 32Mhz processor. Would people recommend using either the NIOS or mircoblaze or should we look at a more traditional processor such as a TI chip? Thanks mike |

You shouldn't compare softcore processors like Nios and Microblaze with old-skool processors like the TI. Softcore processors always require FPGA's and they don't come cheap: count on at least 8$ for very basic versions. Softcore processors are great when you build a system with an FPGA which isn't occupied 100% or which can be upgraded to a larger one for a low price. Softcore processors are great when you want to build a SOC-based system. If you want to develop you're own asic, you should consider implementing free softcore processors like the Leon Sparc en the OpenRisc. If you require more details. Don't hesitate to contact me.
