scan. Note that in this mode, the Pixel Interface activates EOS
within 64 CLK_IN cycles after the last sample of the scan
appears on the PIXEL bus.
For each decoded block, the Pixel Interface outputs one
unsigned sample representing the DC coefficient of the block, on
the most significant eleven bits of the PIXEL bus, and forces the
least significant bit to zero. A sample can follow the previous
sample immediately, on the next clock, or the consecutive
samples can be separated by any number of clock cycles. In the
example shown, the last sample is separated from the previous
one by one clock cycle.
In the example shown in Figure 20, the second block follows the
first with no break. This, however is not necessarily so; the first
sample of the second block could be separated from the last
sample of the first block by any number of clocks. For further dis-
cussion of this, see the DATA FLOW CONTROL section.
Note that if the system logic activates STOP at least 24
clock
cycles before the last data sample of the current block, the Pixel
Interface halts the flow of data at the end of the current block.
Otherwise, it halts the flow at the end of the next block.
