Description

A kind of color bits depth access method and system
Technical field
The invention belongs to image field of storage, more particularly to a kind of color bits depth access method and system.
Background technology
Color depth（Color Depth）Also referred to as color bits depth, it is to use bit（bit）Count to represent digital image number of colors Purpose unit.Bit is the binary unit that computer calculates（Or position）, i.e., manageable most basic data or news in computer Breath.
1 bit image is 21 power (=2), can only show two kinds of colors of B＆W.2 bit shadow Picture, then it is 2 square (=4), 4 kinds of colors can be showed, so in addition to black and white, can also shows between them Two kinds of tones.And 3 bit image, be exactly 23 powers (=8), represent the photo in a width black and white or GTG In, 8 kinds of colors including black and white can be shown.According to above computational methods, 24 bit image can be shown 16,777,216 kinds of colors, the color that naked eyes can be differentiated is sufficiently close to, so it is color (True color) to be referred to as euchroic.
In existing Display Technique, single pixel is stored with 16bit, 18bit, 24bit, 32bit, 48bit etc., more often In 32bit, in view data frame buffer, display controller is only read out to the 24bit among 32bit, you can complete Into display；Wherein 8bit by the frame buffer of internal memory when reading data to display controller, forfeiture effect；Such a phenomenon according to Bus bandwidth so is occupied, increases system power dissipation.
Also, in pixel values such as neighbor pixel appearance, traditionally it is required for being read and writen caching, such as phase Adjacent pixel has 8 to wait pixel value, and each pixel value is 24bit, and traditional technology needs 8 × 24bit data all to write Enter in caching, then also need to once or repeatedly read out, this phenomenon has also accounted for many bus bandwidths, occupies interior Deposit, increase the power consumption of system.
