(should be Processor Defined Radio) – Bandwidth will be a challenge • Imagine streaming video, with Turbo FEC, compression and encryption all pipelined – Battery life will also be a challenge with that bandwidth – Pricing will then be the ultimate challenge Quick Start Training The Future Continues • Software Defined Radio may be the ultimate in algorithmic flexibility, but will be unable to change its hardware configuration . . .without a little help. • The problem with the future is its unknown • CoolRunner-II CPLDs adapt to future I/O ports, memory types and ASSPs and still not deplete batteries!
