Embodiment Construction

[0014] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in names as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

[0015] Please refer to figure 1 , figure 1 is...

Abstract

The invention discloses a microcontroller and a related memory management method. The microcontroller includes a processor and a first memory having at least a workspace, wherein the workspace includes a plurality of blocks; a workspace management unit for managing the workspace of the first memory; and a memory monitor implemented by a hardware circuit for monitoring a plurality of blocks, and recording a plurality of monitoring results corresponding to the plurality of blocks of the first memory, wherein the recorded monitoring results include information on whether data of the plurality of blocks is modified. The microcontroller and related memory management method provided by the present invention can improve the power consumption and computing resources of software cache.

Description

【Technical field】 [0001] This invention relates to memory management, and more particularly to microcontrollers and related memory management methods. 【Background technique】 [0002] For embedded microcontroller (MCU) systems, since cache memory such as Static Random Access Memory (SRAM) is expensive, it is common to use a larger / slower / Higher power memory to provide a large memory space; however, this arrangement consumes a lot of power. Furthermore, regarding cache technology, hardware cache implementation requires higher cost, and pure software cache consumes power and computing resources. Therefore, how to provide a memory management method with lower cost and lower power consumption is an important issue. 【Content of invention】 [0003] In view of this, the present invention provides the following technical solutions: [0004] According to one embodiment of the present invention, a microcontroller is provided, including a processor; a first memory with at least a ...
