Processing functions are those that modify an existing data structure and prepare
that structure for display functions.
Display functions take the processed data structures from memory and generate the
appropriate output stream. As in the case of the decode functions, display functions
can be relatively simple, such as an I
of multi-surface composited display.
All decoded data structures are stored in memory, even when further processing is
not required. This mechanism implies that there is no direct path between input and
output data streams. The memory serves as the buffer to de-couple input and output
data streams. Based on the mode of operation, there may be multiple data structures
in memory for a given input stream. The PNX15xx Series uses the TM3260 CPU and
a timestamping mechanism to determine when a specific memory data structure is to
be displayed.
The PNX15xx Series implements the required decode, processing, and display
functions with a combination of fixed function hardware and TM3260 CPU software
modules. The PNX15xx Series provides a good balance between those functions that
are implemented in fixed hardware and those that are programmed to run on the
TM3260 CPU. The following tables illustrate how the major tasks are implemented
under each of the three main functional areas, and how they map to hardware
resources or software.
