⎯
Bit 26: Indicates whether or not the V IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
•
mbcol: Row position in macroblock units (number of macroblocks)
•
mbrow: Column position in macroblock units (number of macroblocks)
•
Forward_Recon_down: Past-frame vertical-direction vector (half-pixel units)
•
Forward_Recon_right: Past-frame horizontal-direction vector (half-pixel units)
•
Back_Recon_down: Future-frame vertical-direction vector (half-pixel units)
•
Back_Recon_right: Future-frame horizontal-direction vector (half-pixel units)
•
Buffer RAM pointer: Pointer to the buffer RAM 1 in use (RAM 1 address storing IDCT data)
Notes on MC Command FIFO Register (MCCF) Settings:
1. Buffer RAM pointers should point to addresses on 4-byte boundaries. If not, the lower address
is regarded as 0.
2. When setting values in this register in succession, the MC module is able to receive the next
command while the MC_CFF bit in MCSR is 0. To perform processing by changing the
command alone, just set the new command in this register.
3. Four commands can be received. If the next command is written when the command FIFO is
full, the commands stored in the command FIFO are retained and the next command is
ignored.
4. Specify the RAM 1 pointer even when the cbp is set to 6'h00. The specified address should be
H'FE42_0000.
5. In intra macroblock processing mode, the output data values are not guaranteed if the cbp is set
to a value other than 6'h3F.
