[0074] Step 201: Preprocessing multiple analog or digital signals from hardware modules;

[0075] Step 203: start multiple SRIO modules;

[0076] Step 205: Distributing data to multiple SRIO modules in parallel;

[0077] Step 207: Send the data transmitted by the multiple SRIOs to the DSP computing group in parallel.

[0078] Step 209: the multiple SRIO modules send a Doorbell message to the corresponding DSP computing group to inform the DSP computing group of the current data packet status.

[0079] Finally, the FPGA-based data processing system includes a step: DSP receives the data frame.

[0080] The SRIO module of the DSP receives the Doorbell message, that is, a frame of data is received, and the DSP enters the interrupt service program to check the status of the data packet.

[0081] The DSP assembles the received data frame into a complete data packet according to certain rules, and the assembly rule can be selected: through the position index of the circular queue...

Abstract

The invention discloses an FPGA-based parallel data processing method and device. The FPGA-based parallel data processing method includes: preprocessing multiple analog or digital signals from hardware modules; starting multiple SRIO modules; distributing data in parallel to multiple SRIO modules; sending the data transmitted by the multiple SRIOs to DSP calculations in parallel Group. In the present invention, the data transmission interface between FPGA and DSP has multiple SRIO transmission channels, and FPGA sends the same data frame to multiple DSP calculation groups through SRIO at the same time, FPGA sends data frames according to the circular queue, and the DSP calculation group selects from the circular queue The corresponding data packet processing effectively improves the data transmission efficiency between FPGA and DSP computing groups, and reduces excessive waste of DDR3 resources.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to an FPGA-based parallel data processing method, device, computer equipment and readable storage medium. Background technique [0002] At present, digital signal processing equipment has been widely used in voice signal processing, image signal processing and other fields, but it also faces severe technical challenges - greater calculation, more data exchange, more complex signal algorithms, more stringent real-time requirements. [0003] Take SAR radar as an example. The number of sampling points NRN in the range direction of the SAR echo image is 4096, the number of sampling points NAN in the azimuth direction is 2048, the number of bytes occupied by each sampling point is 8 (single-precision complex points), and the maximum synthetic aperture time is 0.5s. Then there are: the amount of data required for a single signal algorithm is 512M bits, data tra...
