Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.

[0018] In one embodiment, a storage module data access control method is provided, such as figure 1 As shown, the method includes:

[0019] Step S110: Detect the peripheral event triggered by the peripheral module.

[0020] Specifically, the peripheral module may be detected through a PES (Peripheral Event System, peripheral event system) module, and if it is detected that the peripheral module triggers a peripheral event, a subsequent access priority control operation is started. There are many modules inside the chip, and each module has many events. These events mark ...

Abstract

The present application relates to a storage module data access control method, a data access device and a chip. The method includes: detecting peripheral events triggered by peripheral modules; and sequentially generating corresponding The peripheral hardware access request signal is sent to the storage module; the peripheral hardware access request signal is used to control the data transmission between the storage module and the corresponding peripheral module. According to the detected peripheral event and the preset event priority, corresponding peripheral access request signals are sequentially generated and sent to the storage module, so as to control the storage module to perform data transmission with the corresponding peripheral module. Through the established event priority, different peripheral events are sequentially called to the storage module for data transmission, which can realize the time-division multiplexing of the same storage module by different peripheral modules, which saves the storage resources of the storage module and reduces the The area and power consumption of the chip are reduced, and the manufacturing cost of the chip is reduced.

Description

technical field [0001] The present application relates to the technical field of data access control, in particular to a storage module data access control method, data access device and chip. Background technique [0002] Random access memory (Random Access Memory, RAM) is an internal memory that directly exchanges data with a CPU (Central Processing Unit, central processing unit), and can be divided into static RAM and dynamic RAM. In MCU (Micro Control Unit, micro control unit) chip design, the size of RAM will affect the cost and area of ​​the chip. Theoretically, the smaller the size of RAM is, the lower the manufacturing cost of the chip is. [0003] With the increase of market demand, the functions of the MCU chip are becoming more and more diversified, which requires more and more internal IP (Intellectual Property, intellectual property) modules. Some of these IP modules need to process a large amount of data. In order to meet the requirements of data processing, t...
