UG-707
pvsp_srscal_interp_mode[1:0]
, Primary VSP Map,
Address 0xE894[7:6]
This signal is used to select the scaler algorithm employed.
Function
pvsp_srscal_interp_mode[1:0
]
Description
00 (default)
Automatic scaler algorithm selection
01
Contour-based interpolation scaler (2nd gen scaling algorithm with 4k x 2k support)
10
Frequency-adaptive scaler (1st gen scaling algorithm)
11
Bilinear scaler
pvsp_srscal_8bit_en
, Primary VSP Map,
Address 0xE890[3]
This bit is used to set the scaler into 8-bit mode. This bit should be set when output 4K x 2K timing.
Function
pvsp_srscal_8bit_en
Description
0 (default)
Scaler not in 8 bit mode
1
Scaler in 8 bit mode
The size of the active image sent to the scaler is set by
to 1, or it can set automatically
. These registers should be set to the resolution of the output video. Refer to
pvsp_man_scal_out_enable
, Primary VSP Map,
Address 0xE883[3]
This bit is used to enable the manual setting of pvsp_scal_out_width and pvsp_scal_out_height.
Function
pvsp_man_scal_out_enable
Description
0 (default)
Disable manually setting M_Scaler output resolution
1
Enable manually setting M_Scaler output resolution
pvsp_scal_out_height[12:0]
, Primary VSP Map,
Address 0xE846[4:0]; Address 0xE847[7:0]
This signal is used to set the output vertical resolution of scaler in the VOM.
Function
pvsp_scal_out_height[12:0]
Description
0x000 (default)
Default
0xXXX
Output height of VOM scaler
pvsp_scal_out_width[12:0]
, Primary VSP Map,
Address 0xE844[4:0]; Address 0xE845[7:0]
This signal is used to set the output horizontal resolution of scaler in the VOM.
Function
pvsp_scal_out_width[12:0]
Description
0x000 (default)
Default
0xXXX
Output width of VOM scaler
