Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 , the present invention uses a slice of SDRAM memory with four banks as the frame memory, and this memory adopts the 32-bit wide SDRAM memory of mt48lc2m32b2 model of Micron Corporation. The four banks are divided into two parts according to the storage content and function. The first part is two of them, bank0 and bank1, which are used to store the 8-field signal used for 3D decoding of stereoscopic composite video signals. The second part includes the remaining two bank2 And bank3, used to store the 4-field YUV4:2:2 signal used to realize binocular stereo display frame rate improvement after decoding.

[0026] The reading and writing control method of the present invention includes two main aspects: storing stereo composite video signals in SDRAM and storing decoded YUV4:2:2 signals in SDRAM. At the same time, because the NTSC system s...

Abstract

The invention discloses a method for the storage and read / write control of a memory for processing binocular stereoscopic-displaying videos. The method ensures that the read-out data can meet the requirements for decoding and stereoscopic dual-output and greatly increase the utilization rate and bandwidth of SDRAM (synchronous dynamic random access memory) by reasonably designing a controlling part and using only one 4-bank frame memory SDRAM, wherein, two banks thereof are used for storing 8 fields of composite video signals and the other two banks thereof are used for storing 4 fields of decoded YUV4:2:2 signals.

Description

technical field [0001] The invention relates to a method for processing data by a binocular stereoscopic display video memory, in particular to a method for storing and reading and writing control using a single-chip SDRAM memory, so as to realize 3D (three-dimensional) composite video decoding and dual Display frame rate boost function. Background technique [0002] Stereoscopic display technology can express the sense of depth, layering and realism of images. It has a wide range of applications and has become the development trend of future display technology. As a representative of stereoscopic display technology, binocular display technology uses two identical display modules for left and right eye display respectively, so that the viewer is not limited by the viewing position, has a larger field of view, and increases viewing freedom and on-site feel. [0003] Stereoscopic video formats based on binocular disparity include left-right format, top-bottom format, interla...
