多DSP处理器HPI接口无缝连接技术研究与实现

随着DSP器件的不断发展，越来越多的数字信号处理技术与方法可以基于DSP器件应用于实践．但是由于某些算法的运算量极大而单片DSP的处理能力有限，为保证运算的实时性要求就必须采用多DSP协同工作来解决这一问题，而多DSP间的高速可靠通信是多处理器结构提高性能的关键．为此提出1种通过HPI接口的无缝连接的方法，无需外加逻辑器件即可实现一对多或多机的同时／分时数据传输．

Research and implementation on technology of multi-DSP seamless connection with HPI interface

With the development of digital signal processor, more and more digital signal processing technologies and methods can be applied to practice based on DSP devices. But some of algorithms are complex and processing capability of single DSP is limited. To ensure the real-time process, multi-DSPs must be employed. However high-speed and reliable communication between multi-DSPs is the key technology to improve the performance of multi-DSP structure. In the paper a method of seamless connection with HPI interface was introduced and multi-DSP communication was implemented without extra logic components.
