Abstract
The authors present a multi-DSP (digital signal processing) system based on commercial chips. The structure is a MIMD (multiple-instruction multiple-data) machine with a data-driven organization. A locally parallel link based on a memory shared between two adjacent nodes assures the asynchronous exchange of data. The system is also characterized by a global serial channel useful for program-loading purposes and noncritical data paths. A mathematical model is used to evaluate the performance of the multi-DSP system. The apparatus is used in ultrasound Doppler parameter estimation but the processing architecture is suitable for general real-time applications
