AVDP7
Advanced Video Display Processor 7
Outline
YGV628B (hereafter called AVDP7) is the latest version of YAMAHA AVDP series which has many past
successful records in various visual equipments, vehicle equipment, etc.
Three bit-map planes are equipped, and it can be displayed in piles to an external image; furthermore, AVDP7
has many functions as OSD (On Screen Display), such as α-blending, change of a display priority, etc. In addition,
it has a digital image Input/Output function to allow an external image to be expanded or reduced.
Moreover, AVDP7 is supports to the resolution up to SVGA, and it is possible to apply to the various digital
equipments only by connecting one SDRAM to an external memory as a frame memory.
Feature
OSD Function
The OSD images which is composed of plains in case of a digital image input is overlaid.
Simultaneous use of three plains is possible in AVDP7 at its maximum.
The natural picture display of 65536 colors by R5bit, G6bit, and B5bit. It is the palette color of 256
colors in 16777216 colors.
Supports 16bit YCrCb422
16 gray-levels of α-blending in dot units
Conversion of display priority is possible
Display Resolution
Creation of the Display Timing of NTSC, PAL, QVGA, Wide QVGA, VGA, Wide VGA, and SVGA is
possible.
Examples of Correspondence Resolution : 320×240, 400×240, 720×240, 640×480, 800×480, 800×600,
etc..
Resolution Converting Function : Horizontal direction Æ 1/2 times to 8192 times display
Vertical direction Æ 1/4 times to 8192 times display.
