SoC

Abstract

The embodiment of the invention provides a system on chip (SoC). The SoC comprises a micro control unit (MCU). The static random access memory SRAM is used for dividing a storage address of the SRAM into a data SRAM and a program SRAM, wherein the data SRAM is used for storing data in the MCU, and the program SRAM is used for storing programs in the MCU; and the SRAM is connected with the MCU through a special bus to store or read data / programs in the MCU. According to the size of the data to be stored in the MCU and the size of the program; according to the technical scheme, the storage spaceof the SRAM is divided through the software program, the data SRAM used for storing data and the program SRAM used for storing programs are obtained, the SRAM reasonably stores the data and the programs in the MCU, and meanwhile repeated utilization can be achieved without changing the physical structure of the SRAM.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a SoC system. Background technique [0002] In a Micro Control Unit (MCU) system, a Static Random-Access Memory (SRAM) is a very precious resource due to area and cost reasons. In an SoC system there is usually a program SRAM for storing programs and a data SRAM for storing data. The size of the SRAM has a great impact on the performance of the SoC system, and the application of the MCU is also very different. Some require a larger program area, and some require a larger data area. Therefore, the storage space of the program SRAM and data SRAM fixedly allocated by the system often does not match the storage space of the program SRAM and data SRAM required by the actual SoC system, which wastes the storage space of the SRAM and reduces the application scenarios of the SoC system. [0003] Such as figure 1 As shown, if the storage space of the program SRAM used to store...
