Embodiment 1

[0042] Such as figure 1 It is a hardware platform and an interface diagram of the comprehensive processing system of the present invention. Relying on the general VPX platform (i.e. VPX processor), with the motherboard switching interface board and the sub-board expansion interface board as the carrier, the two boards each have a ZYNQ-7000 series processor, and the motherboard and daughter board ZYNQ-7000 processor The system architecture see figure 2 . The main feature of the ZYNQ-7000 processor is the dual-core ARM Cortex TM -A9 processor PS and Xilinx7 programmable logic PL are integrated into a single chip. Thus, the ARM processing system and Xilinx7 series programmable logic are perfectly combined, enabling users to create unique and powerful designs.

[0043] ZYNQ-7000 processor system dual-core ARM CORTEX TM - In addition to the dual-core A9 core, the PS part of the A9 processor also includes on-chip memory, external memory interfaces and a series of rich I / O peri...

Embodiment 2

[0054] A kind of software design method of the integrated processing system based on the VPX platform as described in the first embodiment, the integrated processing system software designed in this way performs task division and task management according to the interface type and processing capacity of the integrated processing system, And carry out multi-task scheduling and dynamic allocation of computing nodes, and perform complex process control. The part of the complex algorithm that can be operated in parallel can be combined with the resource usage of the motherboard and daughter board programmable logic PL and the dual-core ARMCortex of the mother board and daughter board. TM -The processing power of the A9 processor PS splits the algorithm into different sub-modules, and the two cooperate to operate, through the dual-core ARM Cortex of the motherboard and the daughter board TM -The interaction of the intermediate results of the high-speed interface between the A9 proce...

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and in particular relates to a comprehensive processing system and a software design method based on a VPX platform. Background technique [0002] With the continuous change of the work tasks and working environment requirements of the precision guided aircraft system, the requirements for the generalization, miniaturization and scalability of the comprehensive processing system of different guidance systems are becoming more and more urgent. [0003] The traditional integrated processing system is mostly realized by the architecture of DSP+FPGA. FPGA mainly completes the interface and timing control, and DSP mainly completes the process control and the realization of complex algorithms. The layout and wiring and data interaction process of the board's main processing chip are relatively complicated. When DSP performs multi-task management, it needs to set a large number of int...
