Abstractdspsr is a high-performance, open-source, object-oriented, digital signal processing software library and application suite for use in radio pulsar astronomy. Written primarily in C++, the library implements an extensive range of modular algorithms that can optionally exploit both multiple-core processors and general-purpose graphics processing units. After over a decade of research and development, dspsr is now stable and in widespread use in the community. This paper presents a detailed description of its functionality, justification of major design decisions, analysis of phase-coherent dispersion removal algorithms, and demonstration of performance on some contemporary microprocessor architectures.

With the development and application of technique on high speed digital signal processing, wide bandwidth processing, high-speed data exchanging and flexible interlink structure have been the developing trend of modern high performance signal processing machine. In this paper, one universal signal processing machine is designed based on six pieces of ADSP-TS201 TigerSHARC processors, which owns good characteristics such as: large memory, excellent processing and data-exchanging performance, reconstitution, good expansibility. This signal processing machine adopts 64Bit, 66MHz CPCI bus standard and supports the function of extending processing performance by interlinking multiple boards. The high-speed data-exchanging is realized with multiple channel optical fiber. Furthermore, it owns board-level BIT function.
