Abstract

The invention relates to a signal processing architecture transplanting method based on a ZYNQ platform, which aims at an original signal processing architecture of a 2DSP + FPGA, and comprises the following steps: S1, summarizing interface interaction between two DSPs, and summarizing interface interaction between the two DSPs and the FPGA respectively; s2, respectively transplanting the codes ofthe two DSPs into the dual cores of the PS end of the ZYNQ platform, and transplanting the codes of the FPGA to the PL end of the ZYNQ platform; s3, completing interface interaction between the two DSPs by using a shared memory between the PS end dual cores of the ZYNQ platform; s4, utilizing a GP bus between the PS end and the PL end of the ZYNQ platform to complete interface interaction betweenthe two DSPs and the FPGA; and S5, completing hardware acceleration of the Fourier transform module by utilizing the direct storage accessor of the PL end of the ZYNQ platform and the IP core of theFourier transform module. Equivalent substitution of a signal processing architecture is realized, and the problem of platform transplantation is solved; and the method is high in universality and suitable for engineering realization.

Description

technical field [0001] The present invention relates to a signal processing architecture transplantation method based on the ZYNQ platform (the industry's first scalable processing platform launched by Xilinx Company), specifically refers to a method for integrating DSP+FPGA (digital signal processing+field programmable gate array) signal A method for transplanting a processing architecture to a low-power ZYNQ platform belongs to the technical field of signal processing. Background technique [0002] ZYNQ 7000 series chips are Xilinx based on Artix-7 (Z-7010, Z-7015, Z-7020), Kintex-7 (Z-7030, Z-7035, Z-7045, Z-7100) A fully programmable SoC chip (system-on-a-chip) launched by the FPGA series, embedded with a dual-core ARM Cortex-A9MPcore hard-core processor, supports a maximum frequency of 1GHz. Embedding CPU (Central Processing Unit) in FPGA is currently the main way to solve all programmable software and hardware. Altera, another major provider of FPGA, also embeds ARM s...
