Embodiment

[0052] Transmit the 256*256 color picture data stored in DDR3 on the PS side with RGB24 encoding format to the FIFO on the PL side, and then read the data back on the PS side to compare the similarities and differences of the picture data before and after transmission. The example system is designed in VivadoIDE (Integrated Development Environment, integrated development environment), and has passed the test on the XilinxZC702 evaluation board. The system hardware block diagram is as follows figure 2 As shown, it includes ZYNQ7 processor system, AXI DataMover, AXI interconnection, FIFO memory and DataMover control core, and they are connected and communicated through the AXI4 bus. The IP core parameters are set as follows:

[0053] 1) The ZYNQ7 processor system settings are as follows: enable the AXI_GP0 interface, AXI_HP0 interface, and AXI_HP2 interface, enable the FPGA clock and set the frequency to 150MHz.

[0054] 2) AXIDataMover enables MM2S and S2MM transmission chann...

Abstract

The invention discloses a Zynq platform PS-PL data interaction device. The Zynq platform PS-PL data interaction device comprises a hardware system environment design based on an IP core and a software control program design based on a custom hardware platform. The hardware system is mainly formed by a ZYNQ7processor system, an AXI DataMover, an AXI interconnection interface, an FIFO memory and a self-designed DataMover control core and other IP cores. The software control program completes parameter setting needed by data transmission, starts the DataMover and detects the data transmission state through reading and writing in a register in the DataMover control core.

Description

technical field [0001] The invention relates to Zynq platform application technology, in particular to a Zynq platform PS (Processing System, processing system) and PL (Programmable Logic, programmable logic) data interaction device. Background technique [0002] The Zynq platform is the industry's first scalable processing platform based on the Xilinx all-programmable SoC (System on Chip, System on Chip) architecture launched by Xilinx. The perfect combination of hardware programmability of programming gate array) achieves unparalleled system performance, flexibility and scalability with system advantages such as low power consumption and low cost, and provides a wide range of solutions for diverse markets. It involves digital systems and signal-intensive applications such as video acquisition and processing, high-speed communication, and high-throughput bridging. [0003] Zynq platform consists of two parts: processor system PS (ProcessingSystem) and programmable logic PL...
