High Performance Floating-point DSPC
ER-DSPC-20A processor is the second generation independent high performance floating-point digital signal processor. On the basis of "ER-DSPC-10", the processor core, command system and peripheral interface are fully upgraded, and the computing power reaches 100 billion floating point operations per second, which is 6 times over the performance of first generation"ER-DSPC-10". It is the DSP with the highest single-core computing performance on the market, and be able to widely used on radar,electronic countermeasures, communications, image processing and other fields.
