Embodiment Construction

[0036] Some embodiments of the present invention will be described in detail below, especially the embodiment of using the memory to operate the optical disc player. However, in addition to the detailed description, the present invention can also be widely applied in other embodiments, and the scope of the present invention is not limited, which is subject to the scope of the patent.

[0037] One object of the present invention is to provide a memory access interleaved mapping method.

[0038] image 3 Be the method flowchart of the present invention, comprise the following steps:

[0039] Step S90: Generate a block index for a data block.

[0040] Step S92: Map the block index to a physical address of a memory according to the block index and a number N, wherein N is the number of banks of the memory.

[0041] Step S94: Store the data block in the above-mentioned physical address of the memory.

[0042] Step S96: Go back to step S90 and repeat the above steps.

Abstract

The invention provides a crossing image method and a device stored by a memory, which comprises generating a block index pointing to a data block. The block index is mapped to a physical address of a memory according to the block index and a number N, wherein N is a number of the memory bank. The data block is stored to the physical address of the memory and the above steps are repeated, wherein the mapping step makes each one of the block indexes map in turns to one physical address located at different banks, and result in any logical adjacent block of data be stored physically at different banks of the memory. The device and the application method ensure no pre-charge load when accessing the outer memory of the disc broadcasting device, thereby shortening access time for writing and reading the memory material.

Description

technical field [0001] The present invention relates to a method and device for interleaved mapping of memory access, in particular to a method and device for reducing the burden of precharging when accessing memory. The method and device can be applied to a CD player to reduce the pre-charging burden of the CD player. Background technique [0002] In recent years, the computer industry has grown faster and faster. Almost everyone has their own personal computer, and computers are used for various things, such as data processing, data recording, information management, and multimedia playback. Wait. A computer system is a combination of hardware, software, and firmware. The hardware includes processors, memory, drives, graphics cards, etc. In order to use this system efficiently, it is very important to cooperate well among the above-mentioned hardware devices, especially the cooperation between the memory and the processor. In addition, the memory configuration is also c...
