• LAT_COMP: Decoder Latency Compensation
Decoder latency compensation value in clock cycles.
If the best case latency (from bus request to bus grant, or from data request to data receive) is known, the value can be
written to these register bits used to compensate the delay. If the latency value is unknown, these bits should be written to
zero.
written to these register bits used to compensate the delay. If the latency value is unknown, these bits should be written to
zero.
Note:
Setting the compensation value higher than the best case latency can cause data corruption.
• DOPF: Decoder Output Picture Format
0: Output format is raster scan, i.e. pixel rows are written in consecutive memory.
1: Output format is tiled, i.e. macroblocks are written in consecutive memory addresses.
• AHB_BURST: AHB Precise Burst and Data Discard Enable
0: INCR bursts of undefined length 2 or 3 may be issued when necessary.
1: Only the precise AHB bursts (SINGLE, INCR4, INCR8 and INCR16) are used in SDRAM read accesses. Extra data is
discarded internally.
discarded internally.
• DI_LE: Decoder Input Endian Mode
0: Big endian.
1: Little endian.
• HTI: Hardware Timeout Interrupt Enable
0:Hardware Timeout Interrupt Disable.
1: Hardware Timeout Interrupt Enable.
