Multi-core network concurrent access method and system of FT-M6678 chip and medium

Abstract

The invention provides a multi-core network concurrent access method and system for an FT-M6678 chip, and a medium, and the method comprises the steps: a network protocol stack initialization step: selecting an embedded network protocol stack, and initializing the embedded network protocol stack; a MAC address virtualization step: enabling a kernel 0 of the FT-M6678 chip to virtualize MAC addresses of kernels 1-7, and forming a local MAC address list together with the MAC address of the kernel 0; and a data core number acquisition step: after the network card equipment receives the data packet, analyzing the data packet by a core 0 of the FT-M6678 chip to obtain a destination MAC address of the data packet, and entering a destination address judgment step. According to the method, multiplecores can use a single Ethernet controller at the same time, and under the condition that a domestic FT-M6678 chip is only provided with one network card controller, data interaction among the multiple cores is completed on a network card driving layer, so that each core of the chip uses a network protocol stack.

Description

technical field [0001] The present invention relates to the technical field of multi-core network concurrency, in particular to a multi-core network concurrent access method, system and medium of the FT-M6678 chip. Background technique [0002] The domestic FT-M6678 chip is a high-performance military multi-core floating-point DSP chip that is benchmarked against TI's TMS320C6678, and is compatible with the TI-C6678 instruction set. The DSP chip contains 8 M66x cores (core 0-7), has fast data processing capability, and provides rich on-chip interface resources, such as Rapid IO, PCIe, SGMII, EMIF, I2C, UART, etc. The chip can be used in radar signal processing, underwater acoustic equipment, electronic countermeasures, graphics and image processing, target tracking and search, missiles and artillery, navigation systems, wireless and mobile communications and other fields. [0003] In the external interface of the domestic FT-M6678 chip, there is a SGMII Ethernet interface, ...

AI Technical Summary

Problems solved by technology

In view of the AMP architecture used by the DSP operating system, each core is independent of each other, each needs to use the network, and the hardware of the FT-M6678 chip does not have the network conditions for multi-core simultaneous use
