UG-707 ADV8005 Hardware Reference Manual
pvsp_fieldbuffer4_addr[31:0] , Primary VSP Map, Address 0xE810[7:0]; Address 0xE811[7:0]; Address 0xE812[7:0]; Address 0xE813[7:0]
This signal is used to set the start address of field/frame buffer 4. Software should arrange memory space properly, avoiding conflict between
different buffers.
Function
pvsp_fieldbuffer4_addr[31:0] Description
0x02495A00 Default
0xXXXXXXXX Start address of field/frame buffer 4
pvsp_fieldbuffer5_addr[31:0] , Primary VSP Map, Address 0xE814[7:0]; Address 0xE815[7:0]; Address 0xE816[7:0]; Address 0xE817[7:0]
This signal is used to set the start address of field/frame buffer 5. Software should arrange memory space properly, avoiding conflict between
different buffers.
Function
pvsp_fieldbuffer5_addr[31:0] Description
0x02C7EA00 Default
0xXXXXXXXX Start address of field/frame buffer 5
pvsp_fieldbuffer6_addr[31:0] , Primary VSP Map,
Address 0xE889[7:0]; Address 0xE88A[7:0]; Address 0xE88B[7:0]; Address 0xE88C[7:0]
This signal is used to set the start address of field/frame buffer 6. Software should arrange memory space properly, avoiding conflict between
different buffers.
Function
pvsp_fieldbuffer6_addr[31:0] Description
0x03073200 Default
0xXXXXXXXX Start address of field/frame buffer 6
3.2.1.5. Frame Latency
Different resolutions have different frame latencies, depending on the timing combination to and from the PVSP. This is due to the increased
processing required in converting and scaling video data.
Table 21 lists the frame latencies in normal mode for various resolutions.

1. x.x means x.x times the input video field/frame
2. A~B means frame latency is not a fixed value, it varies between A and B
3. If cadence detection is disabled, this value should be 0.3~1.4 with setting pvsp_frc_change_phase_en to 0, otherwise is 0.3~3.4
4. If progressive cadence detection is disabled, this value should be 0.3~1.4 with setting pvsp_frc_change_phase_en to 0, otherwise, it is 0.3~3.4
