Abstract

The invention relates to the technical field of configuring a processor in an embedded manner, in particular to a system for configuring a multi-processor in single Flash in an embedded manner. The system comprises a central processing unit, four processor nodes and a Flash memory, wherein the central processing unit is both connected with the four processor nodes and the Flash memory; each processor node comprises an MPC (Multimedia Personal Computer) 7448 processor, a bridge sheet and a double data rate synchronous dynamic random-access memory DDRSDRAM, wherein the DDRSDRAM is connected with the processor, the processor is connected with the bridge sheet and the bridge sheet is connected with the central processing unit; bridge sheets of each two processor nodes are connected through a PCI-X (Peripheral Components Interconnect) bus, and the four processor nodes and four PCI-X buses are connected circularly. According to the invention, the problem of complex traditional structure is solved, the production cost is reduced greatly, and the system provided by the invention has a simple structure, small size and relatively low production cost; furthermore, automatic configuration can be performed according to processor demands and a high-speed serial bus is provided.

Description

technical field [0001] The invention relates to the technical field of embedded configuration processors, in particular to a single Flash embedded configuration multi-processor system. Background technique [0002] PowerPC is a RISC (Reduced Instruction Set Computer) architecture. In the 1990s, IBM, Apple and Motorola successfully developed PowerPC chips and manufactured PowerPC-based multiprocessor computers. The PowerPC architecture is characterized by good scalability, convenience and flexibility. The first generation of PowerPC uses a 0.6um production process, and the transistor integration level reaches 3 million per chip. Motorola designs the PowerPC core into the SoC chip, forming dozens of models of embedded communication processors of the Power QUICC I-III family. [0003] Motorola's embedded processor chips based on PowerPC architecture include nearly dozens of products such as MPC505, 821, 850, 860, 8240, 8245, 8260, 8560, etc. Among them, MPC860 is a typical p...
