Description

technical field

[0001] The invention relates to the technical field of electronics and communication, in particular to the realization technology of the Ethernet interface and the TCP / IP protocol of the high-speed floating-point DSP processor. Background technique

[0002] Since the birth of floating-point digital signal processors (Digital Signal Processors) more than ten years ago, they have provided more advanced alternatives for real-time signal processing.

[0003] Compared with the fixed-point DSP processor, the floating-point DSP processor has the following advantages: (1) The dynamic range of the floating-point DSP is larger than that of the fixed-point DSP. The dynamic range of the 32-bit floating-point DSP can reach 1536dB, which not only achieves extremely high computing precision, but also greatly saves computing time and storage space. Reduced checks for shifts, overflows, etc. (2) Because the floating-point DSP processor can complete a floating-point operatio...
