Abstract :
The best way to build chips or chipsets for mobile TV receivers is to create flexible solutions that can handle multiple standards and address sliding modifications to existing standards. The good news is that many of these standards share similar algorithms for channel demodulation and channel decoding (OFDM, Viterbi decoding, xPSK, FFT, and so on). This requirement for flexibility is driving a new segment of processor development, especially in the DSP area. Solutions such as ARC´s and CEVA´s configurable cores and Improv Systems´ JazzDSP are ideal vehicles for creating custom processors as programmable solutions for digital processing of channel demodulation and channel decoding.
