4.0.1 PNX1300 Series versus PNX15xx/952x Series VLD
5.1 PNX1300 Series and PNX15xx/952x Series Register Differences
5.2 VLD Register Summary
The current VLD is a compatible superset of the VLD that was implemented in the
PNX1300 Series chip. Differences in the register definitions are noted in
text.
The PNX15xx/952x Series implementation removed the RL/MBH write-back DMA
channels. Differences from the current VLD implementation are noted in
The base address for the PNX15xx/952x Series VLD module is 0x07 5000.

The MPEG-2 Macroblock Header Output Format now differs in two ways: the
First Forward Motion Vector bit[1] which was unused is now the “First Macro
Block” bit, and the sixth word bits[23:16] now contain the Slice Start Code.
The PNX1300 Series does not implement the “Parse Long” command.
In the VLD_STATUS register, the PNX1300 Series does not implement the
following bits:
–
In the VLD_CONTROL register, the PNX1300 Series does not implement the
following bits:
–
–
–
In addition, the Little_Endian mode bit is on bit[1] in the PNX1300 Series; but it is
bit[0] in this module.
Bit[6] RL Overflow
Bit[16] Slice_strobe
Bit[15:8] Slice_start_code
Bit[2] DMA_input_done_mode
