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
