TMS320F2812 is a kind of newly designed high-precision control DSP chip produced by Texas Instruments(TI).The design of information processing system based on TMS320F2812 double-DSP platform which has the abundant on-chip resources and better data-processing ability is introduced. It has characteristics of higher speed, more mighty function, lower cost, stronger universality and so on. This platform can make up for the disadvantage that in single-DSP system, when a large number of data input/output and interface burst signal are processed , instability of the system being induced result in data loss. The double-DSP platform can be used as an embedded system hardware platform to further enlarge new application fields such as optical networking, auto-control, biomedicine and so on.
