A storage-sharing multi-chip processor system based on a bridge chip and its starting method

Abstract

The invention provides a bridge chip-based storage sharing type multi-chip processor system and its starting method. The storage-sharing multi-chip processor system includes: m processors, a storage medium and a bridge chip, where m is a positive integer greater than 1; wherein, one of the m processors communicates with the processor through a storage interface Storage medium connection, the processor is the main boot processor; the remaining m-1 processors are slave boot processors; the m processors are respectively connected to the bridge chip through their respective data communication interfaces; when starting, the main boot processor Boot through the storage interface, and boot from the boot processor through the data communication interface. The system only needs to configure a storage medium for the main boot processor, reducing storage medium usage and saving board area. In addition, the system does not need to add an independent boot file transmission channel for the slave boot processor by multiplexing the data channel of the processor, thereby reducing hardware cost and design difficulty.

Description

Technical field [0001] The present invention relates to the field of computer technology, and more particularly to a bridging storage shared multi-plate processor system and its startup method thereof. Background technique [0002] When the embedded board processor starts, you need to get the start boot program and the operating system image from the storage medium. In order to achieve higher computing power, a common way is to integrate a plurality of processors on the embedded panel. At this time, a separate storage medium is generally configured on the embedded board, and the startup boot program of each processor is stored, and the operating system mirror image is stored. When the processor is started, each processor is from the respective storage media. Get the start boot program to start with the operating system image. However, configuring a separate storage medium for each piece of processor will take up a large number of plate covers, increasing the cost of the device an...

Problems solved by technology

However, when the processor is started based on the storage medium, it is still necessary to configure an independent startup file transmission channel for each processor, import the bootloader and the operating system image from the storage medium, and fail to effectively utilize the data communication transmission channel realized by the bridge chip. Additional hardware and PCB wiring are added, increasing hardware cost and design difficulty
