Embodiment Construction

[0066] Certain terms are used throughout this patent specification and the following claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This description and the following claims do not use the difference in name as the way to distinguish components, but the difference in function of the components as the criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". Otherwise, the term "coupled" includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a 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.

Abstract

The invention discloses a memory access control device and a relevant control method thereof. The invention discloses the memory access control device, which comprises a plurality of memory access requirement generation modules and an arbitrator. When receiving a second memory access event in a first data access operation which is performed by a memory according to a first memory access requirement corresponding to a first memory access event, one of the plurality of memory access requirement generation modules outputs a second memory access requirement corresponding to the second memory access event to the memory after a delay time; and the arbitrator arbitrates the memory access requirements output by the plurality of memory access requirement generation modules.

Description

technical field [0001] The present invention relates to a memory access control device and its related control method, in particular to a method for selectively delaying a subsequent one when a first write request and a first read request of a single-port memory overlap. The time for issuing the second write request, so that the second write request can be normally sent to the access arbitration device of the single-port memory and its related control method. Background technique [0002] With the evolution of technology and the sharp increase in the functional requirements of users for information systems, the speed and accuracy of reading, transmitting, storing, using, and displaying various information must be continuously improved, which affects the performance of information systems Most notably, the associated memory access operations within the system. [0003] Therefore, how to control the access efficiency of the memory to continuously improve the performance of th...
