Embodiment Construction

[0042]In the embodiment of the present invention, a pipeline is introduced to provide data reading services for the CPU. After the work of the address mapping stage in the pipeline is determined to be completed, a data request message is taken out of the pipeline waiting queue for storing the data request message sent by the CPU. , and put the fetched data request message into the pipeline for processing; adopting the embodiment of the present invention, the next data request message can be processed simultaneously after the work in the address mapping stage is completed, without having to wait until the address mapping, permission The next data request message can be processed only after the three phases of the bit check and whether the cache check is allowed to be executed, so that the execution efficiency of data reading can be effectively improved.

[0043] The embodiments of the present invention will be further described in detail below in conjunction with the accompanyin...

Abstract

The invention relates to the technical field of communication, in particular to a data processing method and device. The data processing method and device are used for solving the problems that in an existing internal storage access process, all access steps are executed in series, and then the access efficiency is low. The data processing method comprises the steps that it is determined that work in the address mapping section in a flow line is completed, wherein the flow line is used for providing a data reading service for a CPU, and the data reading service comprises the three sequentially executed work stages involving address mapping, permission bit checking and checking of the fact whether accessing is allowed or not; a data request message is taken out from a flow line waiting queue, and the taken data request message is placed in the line to be processed. By the adoption of the data processing method and device, after the work of the address mapping stage is completed, a next data request message can be processed, it is avoided that the next data request message is processed after the work of all the three stages is completed, and therefore the execution efficiency of data reading is effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data processing method and device. Background technique [0002] With the development of graphical interface applications, the physical memory with a small memory capacity (on the order of K) can no longer match the scale of the program; to solve this problem, a solution is to divide the program into small pieces and load them into the memory one by one, but This solution is complicated to implement and has low efficiency; another solution is to use virtual memory, so that the total size of data and stacks can exceed the size of physical memory, and the operating system will keep part of the currently used data in memory, while Other unused part of the data is saved on the disk, and the address mapping and memory access control during the data reading process are implemented by the Memory Management Unit (MMU). [0003] When the MMU performs address mapping an...
