Outline
Multi rate and multi format video encoder that supports NTSC/PAL and ITU-601/SQ (square pixel).
10bit-1chD/A converter that integrates 7Ω driver.
Can be connected to TV directly without OP-amp or buffer.
Support 8/9/16/18/24bit bus (D, WR, RD, CS, A0) of I80 type.
It corresponds to 5 format of RGB565, RGB666, YUV422 (8bit), YUV422 (8bit_BT656mode), and YUV422
(16bit). The writing operation is executed based on Sync signals.
Controls built-in (MCP) 16MbitSDRAM. Owns arbitration function and CPU access (drawing) is possible
as needed.
Performs RGB → YUV conversion at the time of CPU → memory writing.
Performs RGB → YUV conversion at the time of video port → memory writing.
Generates high-speed clock for SDRAM.
A reading binary image from SDRAM is displayed in TV. Because the Alfa blend function is installed, it is
possible to select four stages by blend register.
×4 scaling processing at maximum is executed for reading image from SDRAM.
Can be set to H and V direction independently.
The issue of the command of each screen is unnecessary. Writing/reading control in the image area (two
bank or3 bank) set beforehand is executed automatically.
Can insert CGMS-A/WSS code into V-blanking period.
