Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] see figure 1 , The minimum system of the P4080 processor of the present invention includes a central processing unit, a local dynamic memory, a high-speed serial bus, a power supply system, a clock system, and the like. The central processing unit completes the operation including operating system instructions and user programs. The processor integrates eight e500 cores with a single core speed of 1.5GHz. Each core has a dedicated L2 cache. Eight cores can work as eight symmetric multiprocessor cores or eight asymmetric multiprocessor cores. The processor integrates a memory controller, an LBC bus interface, and a richly configurable Serdes interface function. The invention designs 4GB DDR3 onboard memory particles, and expands 512MB Nor Flash and 2GB Nand Flash storage devices through the LBC bus. The 4X4RapidIO bus is extended through the RapidIO ...

Abstract

An embedded processing module based on a P4080 processor comprises a P4080 processor minimum system and a power module. The P4080 processor minimum system extends an external function through a VPX connector, the P4080 processor minimum system exchanges data with an external device through a high-speed I / O port, the power module includes an input power supply and a processor core secondary power supply adopting a PWM switching power supply, and supply voltage and output current are adjusted dynamically with a processor load. The embedded processing module based on a P4080 processor adopts a standardized VPX structure, can realize the extension of a storage device through an eLBC bus, has a relatively good environment adaptation capability, can combine a symmetrical multiprocessor and an asymmetrical multiprocessor to realize different levels of operation, thus flexibly distinguishes control, data path and application processing, meets the application requirement of an open type military computer, and has very high universality.

Description

technical field [0001] The invention relates to a computer core module, in particular to an embedded processing module based on a P4080 processor. Background technique [0002] With the increasing demand for multi-tasking environment in the process of use, in order to reduce costs and improve performance, the application layer has more requirements for multi-core processing modules. At present, the multi-core embedded processing modules based on PowerPC architecture have the following essential characteristics: Distributed processing runs on multiple heterogeneous processing units, which makes users have to face the challenges brought by asymmetric multiprocessors and complex on-chip interconnections. Therefore, it is necessary to design a processing module that can combine symmetric multiprocessors and asymmetric multiprocessors to achieve different levels of operations, distinguishing between control, data path and application processing. Contents of the invention [00...
