7.3.2.1
F4 Index 10h, Base Address Register 0 (F4BAR0) sets the
base address that allows PCI access to the Video Proces-
sor support registers, not including VIP. A separate base
address register (F4BAR2) is used to access VIP support
registers (see Section 7.3.2.2 on page 359).

Video Processor Support Registers - F4BAR0
Description
Reserved. Must be set to 0.
EN_42X (Enable 4:2:x Format). Allows format selection.
0: 4:2:2 format.
1: 4:2:0 format.
Note: When input video stream is RGB (i.e., F4BAR0+Memory Offset 4Ch[13] = 1), this bit must be set to 0.
BIT_8_LINE_SIZE. When enabled, this bit increases line size from VID_LIN_SIZ (bits [15:8]) DWORDs by adding 256
DWORDs.
0: Disable.
1: Enable.
Reserved. Must be set to 0.
INIT_RD_ADDR (Initial Buffer Read Address). This field preloads the starting read address for the line buffers at the
beginning of each display line. It is used for hardware clipping of the video window at the left edge of the active display. It
represents the DWORD address of the source pixel which is to be displayed first.
For an unclipped window, this value should be 0. For 4:2:0 format, set bits [17:16] to 00.
VID_LIN_SIZ (Video Line Size). Represents the number of DWORDs that make up the horizontal size of the source video
data.
YFILT_EN (Y Filter Enable). Enables/disables the vertical filter.
0: Disable. Upscaling done by repeating pixels.
1: Enable. Upscaling done by interpolating pixels.
Note: This bit is used with Y upscaling logic. Reset to 0 when not required.
XFILT_EN (X Filter Enable). Enables/disables the horizontal filter.
0: Disable. Upscaling done by repeating pixels.
1: Enable. Upscaling done by interpolating pixels.
Note: This bit is used with X upscaling logic. Reset to 0 when not required.
Reserved.
VID_FMT (Video Format). Byte ordering of video data on the Video Input bus (VPD[7:0]). The interpretation of these bits
depends on the settings of bit 13 (GV_SEL) in the Video De-Interlacing and Alpha Control register (F4BAR0+Memory Offset
4Ch) and bit 28 (EN_42X) of this register.
If GV_SEL = 0 and EN_42X = 0:
00: Cb Y0 Cr Y1
01: Y1 Cr Y0 Cb
If GV_SEL = 0 and EN_42X = 1:
00: Y0 Y1 Y2 Y3
01: Y3 Y2 Y1 Y0
If GV_SEL = 1 and EN_42X = 0:
00: P1L P1M P2L P2M
01: P2M P2L P1M P1L
If GV_SEL = 1 and EN_42X = 1: Reserved
Note:
Reserved.
Table 7-9. F4BAR0+Memory Offset: Video Processor Configuration Registers
Both RGB 5:6:5 and YUV 4:2:2 contain two pixels in each 32-bit DWORD. YUV 4:2:0 contains a stream of Y data
for each line, followed by U and V data for that same line.

Note: Reserved bits that are not defined as “must be set
to 0 or 1" should be written with a value that is read
from them.
