ADVANCE INFORMATION
Figure 18 shows activation of STOP by the Pixel Interface, and
the required response of the external system logic in halting the
flow of samples. The Pixel Interface activates STOP when three
of the four Coefficient Buffers are full, so the system must
respond by halting after the last sample of the current block.
The system must activate EOS together with the last image
sample of a scan, as shown in Figure 19.
JPEG Baseline Decoding
In JPEG Baseline decoding, the Pixel Interface places the data
samples on the most significant eight bits of the PIXEL bus and
zeros the other four bits.
Figure 20 and Figure 21 show the beginning and end of a scan,
respectively, in JPEG Baseline decoding.
