2.2.3 Sync Signal Input Pins
SSYNC
This is a sync signal for the DSWI port. It is asserted low. This signal must be
asserted when the leading data for DSWI is inputted
MSYNC
This is a sync signal for the DMBI port. It is asserted low. This signal must be
asserted when the leading data for DMBI is inputted
ESYNC
This is a sync signal for the block level pipeline. When this signal is asserted,
one execution cycle (550
/ 806
cycles) is activated. It is asserted low.
DSYNC
This is a sync signal for the DCNT port. It must be asserted when dynamic
control signal is inputted. See DCNT for the content of the dynamic control
signal. This signal is asserted low.
OREQC
This is used to request output. M65727 starts output from DOUT port after this
signal is asserted. This signal is asserted low.
2.2.4 Pins Specifying Operational Modes
MODE
This pin sets the mode of the M65727. The following four modes can be
specified.
00: Field mode, 01: Frame mode,
10: Field Dual-Prime mode, 11: Frame Dual-Prime mode
HSIZE
This pin specifies the horizontal search range. The following five types of range
can be specified.
000: ±7.5, 001: ±15.5, 010: ±31.5, 011: ±63.5, 100: ±127.5, 101~ 111: reserved
VSIZE
This pin specifies the vertical search range. The following two types of range
can be specified. 0: ±7.5, 1: ±15.5
EXTND
This pin specifies the vertical search range expansion. When expansion modes
are selected, the vertical search range is set to ±8.0 / ±16.0. It is possible to
expand a vertical search range using multiple chips. Depending on modes, the
order of priority regarding the vectors with same distortions is different.
00: non-expansion, 01: reserved,
10: upper-range of expansion, 11: lower-range of expansion
HLFPL
This switches between half-pel precision search mode and integer-pel precision
search mode. 0: Integer-pel precision search, 1: half-pel precision search
FMFMT
Switches between the external memory (SW image) formats.
0: Field format, 1: Frame format
This is a dynamic control input. (Dynamic control means the control which
differs in each execution cycle.) The following is required.
Control of valid or invalid for search range (SKILL)
Leading pixel location of search window image in the vertical direction when the
dual-prime mode (DVSPO)
The central position of the search window image used for the dual-prime mode
(DCNTR)
