Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] As mentioned in the background technology, in order to improve memory access performance, the existing technology adopts a dual-channel memory access control strategy, but its applicable objects are generally limited to personal computers and other terminal devices that are not sensitive to power consumption. More sensitive end devices are not well suited.

[0037] Considering that terminal equipment has a variety of product application forms, and the product application form of terminal equipment can generally be reflected by the sensitivity of terminal equipment to power consumption and performance during application, for example: high sensitivity to power consumption, It indicates that the terminal equipment has low power consump...

Abstract

A memory access control method and device for a terminal device. The memory has at least two access channels. The method includes: using the second balance mode as the memory access mode to allocate access requests on each access channel; In the balanced mode, the entire storage space of the memory is divided into the second sub-storage space corresponding to each access channel according to the storage address range, and the corresponding access mode is determined by address decoding the extended address in the access request; the access The methods include the first access method of realizing non-interleaved access in each second sub-storage space, and the second access method of realizing interleaved access in the virtual access area. The access address in the virtual access area is based on the size of the interleaved access. The unit is a virtual storage address interleavedly mapped to the physical storage address of each second sub-storage space. This solution can achieve a balance between performance improvement and power consumption control to meet the memory access requirements of various applications of the terminal device.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for controlling memory access of terminal equipment. Background technique [0002] As the application of consumer electronic products becomes more and more abundant, the functions provided by the chip are also increasing, which also has very high requirements for the performance of the chip. The processing speed of the central processing unit (CPU, Central Processing Unit) and the number of other bus master control units (Masters) similar to the CPU are also increasing, and the accesses issued by each master have higher and higher bandwidth requirements. , so memory gradually becomes the bottleneck of efficiency. Especially for mobile communication terminal equipment (such as mobile phones), on the one hand, with the introduction of high-speed network standards such as Long Term Evolution (LTE, Long Term Evolution), the amount of network data is increasing; on the ot...
