Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] Memory is an integral part of maintaining the normal operation of embedded devices. Memory is used to store programs or data or codes. When the CPU is running, it calls relevant program instructions from the memory to complete the configuration of related functions. For example, the memory can store program instructions for initialization, and the CPU calls and executes the program instructions to complete the software on Or initial configuration on hardware. However, for the program space of some embedded devices, its storage capacity is often limited. To expand the capacity of the progr...

Abstract

The invention relates to the technical field of communication, and in particular relates to a data operation method as well as a device, an application, a single chip microcomputer and an embedded system thereof. The data operation method comprises the following steps: when detecting Bank switching operation, confirming a first target Bank of a first storage module, wherein programs or data which are loaded into any second target Bank in a second storage module are stored in the first target Bank; and operating the second target Bank of the second storage module according to the first target Bank. Therefore, when the programs or the data of a bank are reloaded into the second storage module, the second target Bank of the second storage module can be flexibly configured according to programs or data of the first target Bank of the first storage module, and thus the efficiency of Bank division is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data operation method and its device, application, single-chip microcomputer and embedded system. Background technique [0002] The program space of electronic devices is often limited. For example, the program space of 8051 single-chip microcomputer is only 64K bytes. When the program capacity of 8051 single-chip microcomputer exceeds 64K, the existing method is to expand the program space through code paging (Code Banking). The principle of code paging is to divide the storage space into different Pages, the jump of the program in different pages is realized by means of chip selection. For example, the expanded 64K program space is divided into 32K public area and 32K bank area. When you need to use the program of a certain bank, directly switch the 32K bank area to the required bank. [0003] In the process of realizing the present invention, the inventor found that...
