Memory control device, mobile terminal, memory control program, and computer-readable recording medium

Abstract

This memory control device comprises a write-in start position control unit (36) that, when a write-in operation is started, performs a predetermined process for shifting the position for starting the write-in operation by a predetermined shifting amount such that the capacity reserved in advance in a frame memory (31) is not exceeded.

Description

technical field

[0001] The present invention relates to a memory control device that writes data transferred from a host processor into a frame memory, reads the data written into the frame memory, and transfers the data to a display panel such as an LCD (Liquid Crystal Display: liquid crystal display), and includes the memory A portable terminal of the control device, a memory control program, and a computer-readable recording medium on which the memory control program is recorded. Background technique

[0002] Generally, when image data is transmitted from a main processor (hereinafter simply referred to as "host") to a display panel such as an LCD, the image data is a frame temporarily stored in an LCDC (LCD Controller: LCD Controller). The memory (hereinafter simply referred to as "memory") is output to the display panel. Accordingly, when there is no update of display data, there is no need to transfer image data from the host computer.
