Optimizing synchronization in multiprocessor DSP systems
This paper is concerned with multiprocessor implementations of embedded applications specified as iterative dataflow programs, in which synchronization overhead can be significant. We develop techniques to alleviate this overhead by determining a minimal set of processor synchronizations that are essential for correct execution. Our study is based in the context of self-timed execution of itera...
متن کاملWhy Multiprocessor DSP Systems Need
In larger development projects, DSP programming groups often operate in a separate silo from the GPP and FPGA programmers. This is a problem because the groups must coordinate their efforts in order to design an optimal system architecture and to allocate functionality optimally. This coordination can be time-consuming and challenging. What's more, any changes to the system architecture or func...
متن کاملResynchronization for Multiprocessor DSP Systems
This paper introduces a technique, called resynchronization, for reducing synchronization overhead in multiprocessor implementations of digital signal processing (DSP) systems. The technique applies to arbitrary collections of dedicated, programmable or configurable processors, such as combinations of programmable DSP’s, ASICS, and FPGA subsystems. Thus, it is particularly well-suited to the ev...
متن کاملMultiprocessor DSP Systems for Active Control
To extend the upper limiting frequency and attenuation zone of active noise and vibration control systems, multiple channel control systems are commonly used. This brings a huge amount of computational load and often multiprocessor DSP systems have to be used. In this paper, several multiprocessor system architectures are considered for the most commonly used active control algorithm, and three...
