Our problem consists of a partially ordered set of tasks communicating over a shared bus which are to be mapped to a heterogeneous multiprocessor system. The goal is to minimize the makespan, while satisfying constrains implied by data dependencies and exclusive resource usage. We present a new efficient heuristic approach based on list scheduling and(More)
Most of the existing Digital Signal Processors (DSPs) are optimized for a fast and e cient computation of the Fast Fourier Transform (FFT). However, there are only two oating-point DSPs available, which perform the butter y operation of a FFT in 4 processor cycles, but no xed-point DSP is designed that way. The new 24 bit xed-point DSP DAISY, which is able(More)
