Advanced Video Display Processor 6
s
Outline
YGV619 is a VDP (Video Display Processor) adopting OSD display control system
which 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 image signal,
and to produce clock best suited to SDRAM that is adopted as external video memory.

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 >
l
D31-0
(
(
(
(I/O: Pull Up))))
CPU data bus. D31-16 pins are not used for 16 bit CPU (LWD=0).
These pins are provided with a pull-up resistor.
Unused pins are to be open.
l
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 32 bit CPU or A7-
2 and
A1
/
WR3 pin for 16 bit CPU. Systems that control AVDP6 only with CSREG do not use this address bus.
However, A23-8 pins must be open because they are provided with pull-up resistor. All the addresses are valid when
accessing
CSMEM space.
l
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.
l
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.
l
LWD
(I: Pull Up)
Selects a CPU data bus width. When high level signal is inputted to this pin, AVDP6 operates as CPU 32 bit device, or
when low level signal is inputted to this pin, AVDP6 operates as CPU 16 bit device.
l
A1
/
WR3 , WR2-0
(
(
(
(I))))
Controls write access to AVDP6 when chip select input signal is active.
A1
/
WR3 control D31-24, WR2 controls
D23-16,
WR1 controls D15-8, and WR0 controls D7-0.
For 16 bit CPU,
A1
/
WR3 function as A1 of CPU address. WR2 is not used, and thus must be open because the pin is
provided with a pull-up resistor.
l
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 16 bit CPU, only D15-0 pins are in output state and D31-16 pins are in input states
at all times.
l
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.
l
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.
l
INT
(
(
(
(O))))
Interrupt request signal output to CPU. This pin becomes active when internal state of AVDP6 coincides with the
setting conditions of the registers, and is reset when internal registers of AVDP6 are accessed.
