BDTI Benchmarks for picoChip PC102 multicore-DSP
According to Berkeley Design Technology (BDTI) benchmarks, picoChip’s PC102 multicore signal processing device has a 40-fold advantage in price-performance over traditional DSP processors solutions in key communications benchmarks, and 8-times higher absolute performance.
The BDTI Communications Benchmark (OFDM)(TM) shows that the PC102 picoArray(TM) can implement 14 benchmark channels in a single device running 160MHz. This represents a cost per channel of $6.78, some 40 times less than the figure for competing traditional DSPs.
The BDTI Communication Benchmark (OFDM) is designed to be representative of the signal processing workloads found in communications equipment for applications such as DSL, cable modems and wireless systems. It is intended to enable benchmarking and comparison of a wide range of devices on real-world, datapath-focused applications. Each channel of the benchmark is a representative model of an Orthogonal Frequency Division Multiplex (OFDM) modem, including filter, Fast Fourier Transform (FFT), slicer and Viterbi decoder.
