Method and device for starting processor

Abstract

The embodiment of the invention relates to the technical field of communication and in particular relates to a method and device for starting a processor so as to solve the problems that external program loading interfaces are too many and too much PCB (printed circuit board) area is occupied as the master and slave processors respectively need a program memory, and the maintenance process of the boot program and software program files is excessively complicated in the prior art. The method provided by the embodiment of the invention comprises: after initialization, the master processor executes a first software program file required by the master processor in a program loader to finish the start, and stores the starting parameter and the program loader into a first memory corresponding to the master processor from the second software program file required for the slave master; and after the initialization, the slave processor finishes the start through the starting program and second software program file in the first memory. The method provided by the embodiment of the invention can be used for reducing the external program loading interfaces, reducing the PCB area and simplifying the maintenance process of the boot program and software program file.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for starting a processor. Background technique [0002] In order to meet the high-performance and low-cost requirements of communication equipment, the performance of the single board in the equipment needs to be greatly improved. Single processors and single-core processors can no longer meet these requirements. Multi-core processors or even multiple multi-core processors are required to cooperate. Complete large-scale computing and data business processing. There are two types of multiprocessor systems: symmetric and asymmetric. [0003] The status of multiple processors in the symmetric architecture is completely equal, and each runs its own program without being controlled by other processors. There are master and slave in the asymmetric architecture, and the slave processor needs to be controlled by the master processor during the running of the ...
