AVDP6
Advanced Video Display Processor 6
s
Outline
YGV619 (AVDP6) is a VDP (Video Display Processor) adopting OSD display control system that is best
suited to the data broadcasting. The digital image interface of this device for connection with
MPEG decoder has
been improved.
The use of this device allows screen composition that is suited to mobile information terminals,
car navigation system, etc. Scan timing conforming to the display standard of digital TVs can be made.
Two built-in PLL circuits allows to realize superimposition of external image signal on original one, and to
produce clock best suited to SDRAM that is adopted as external video memory.

Up to four planes, which are individually composed of backdrop plane (plane on which external images are inputted)
+ region, are available.

AVDP6 performs parallel processing including operation of writing display data into video memory (SDRAM)
connected on the local bus (drawing function) and operation of sequentially reading bit map image stored in the
video memory in accordance with monitor scanning (display function).
Drawing function:
This function transfers bit map image data configured on the external memory of CPU to video memory. For the
transfer of the data, a method that maps the video memory as external memory managed by CPU and performs the
transfer as the transfer between external memories of CPU, or a method that uses internal drawing processor of
AVDP6 to configure the display image on the video memory can be used.
Display function:
This function displays the bit map image stored in the video memory in accordance with the display parameters
that are stored in the internal registers of
AVDP6 and the video memory.
Basically,
AVDP6 automatically sends
out display data and refreshes SDRAM once initial setting for internal registers are completed. When performing
dynamic processing such as scroll, the processing that synchronizes with the scanning of
AVDP6 can be performed
easily by using internal flag polling of
AVDP6 or interrupt function.

Pin Functions
< CPU INTERFACE >
D31-0
(I/O: Pull Up)
CPU data bus.
D31-16 pins are not used for 16bit CPU (LWD=0). These pins are provided with a pull-up resistor.
A23-8
(I: Pull Up),
A7-2
(I)
CPU address bus.
When accessing CSREG space, signals inputted to A23-8 pins are ignored without regarding to the bus width of CPU.
Internal registers are selected depending on the state of signals inputted to A7-2 for 32bit CPU or A7-2 and A1
/
WR3
pin for 16bit CPU. Systems that control AVDP6 only with CSREG do not use this address bus.
A23-8 pins are provided with pull-up resistor.
All the addresses are valid when accessing CSMEM space.
CSREG
(I)
Chip select signal input to REG space.
Internal registers of AVDP6 are accessed by a using write / read pulse that is inputted when the chip select signal is
active. When this signal is low, inputs to A23-8 pins are ignored.
CSMEM
(I)
CSMEM is made active when directly mapping the video memory connected to local bus of AVDP6 on the memory
space of CPU. The video memory managed by AVDP6 is directly accessed using write / read pulse that is inputted with
this chip select signal is active. The video memory can be accessed from REG space without using this pin, however,
high level signal must be inputted to CSMEM in this case.
LWD
(I: Pull Up)
Selects a CPU data bus width.
When high level signal is inputted to this pin, AVDP6 operates as CPU 32bit device, or when low level signal is
inputted to this pin, AVDP6 operates as CPU 16bit device.
A1
/
WR3
(I)
, WR2
(I: Pull Up),
WR1-0
(I)
Controls write access to AVDP6 when chip select input signal is active.
A1
/
WR3 controls D31-24, WR2 controls D23-16, WR1 controls D15-8, and WR0 controls D7-0. For 16bit CPU,
A1
/
WR3 function as A1 of CPU address. WR2 is not used, the pin is provided with a pull-up resistor.
RD
(I)
Controls read access to AVDP6 when chip select input signal is active.
D31-0 pins are in output state while this signal and chip select signals are active.
For 16bit CPU, only D15-0 pins are in output state and D31-16 pins are in input states at all times.
WAIT
(O: Pull Up, 3-state output)
Data wait signal output to CPU.
When CSREG pin or CSMEM pin (hereafter called "CS pin") is active, the
WAIT signal is asserted once for RD
or
A1
/
WR3 and WR2-0 signals, and then negated when AVDP6 becomes accessible. This pin becomes high
impedance state when CS pin is not active, and outputs high level signal when CS pin is active and RD or A1
/
WR3
and WR2-0 pins are not active.
Use this pin or READY depending on the type of CPU.
READY
(O: Pull Up, 3-state output)
Data ready signal output to CPU.
When AVDP6 becomes accessible, this signal is asserted. This pin becomes high impedance state when
CS pin is not
active, outputs high level signal when CS pin is active and RD or A1
/
WR3, WR2-0 pins are not active.
Use this pin or
WAIT depending on the type of CPU.
