Real-time communication method and real-time communication system between dsp and fpga

Abstract

The invention discloses a real-time communication method and system between a DSP and an FPGA. The real-time communication method between the DSP and the FPGA includes the steps that all data, stored in the DSP, to be transmitted are moved and stored in a data transmitting register every time one transmitting frame synchronizing signal of the FPGA is received, the data, temporarily stored in the data transmitting register, to be transmitted are transmitted to the data transmitting flow of the FPGA at the same time when the next transmitting frame synchronizing signal of the FPGA is received, one part of received data of a specific data length, which are input by the FPGA at the same time, are received every time one receiving frame synchronizing signal of the FPGA is received, the part of received data are stored in a data receiving register, and accordingly the part of received data stored in the data receiving register are transmitted to the data receiving flow of the DSP. By means of the real-time communication method and system between the DSP and the FPGA, the data exchange rate between the DSP and the FPGA is greatly increased, bothway, real-time and efficient transmission of the data between the DSP and the FPGA is achieved, and the requirement for acquiring instant messaging services of users is met.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically, relates to a real-time communication method and a real-time communication system between a DSP and an FPGA. Background technique [0002] In the field of data processing chips, DSP has a very high data processing rate, and FPGA chips have high flexibility due to reprogrammability. The industry usually uses a combination of DSP and FPGA to build a signal processing chip with high data processing efficiency. system. Since the communication system (such as GSM, TD-SCDMA) has strict restrictions on the processing time of the transmitted data, it is expected to achieve real-time processing of the transmitted data and meet the user's requirements for instant communication. However, in the above-mentioned signal processing system, there is still a certain delay in the data exchange process between DSP and FPGA. Limited by the data exchange efficiency between DSP and FPGA, ...
