2.1 TRIMEDIA
PROCESSOR
The core of the Inca is the TriMedia 1300 processor. This
Very Long Instruction Word CPU (max. 5 parallel
instructions) with image co-processor runs on 180 MHz.
Among others, this processor handles:
Image and control data flows
Storage of acquired images. The images are stored in the
32 MByte on-board SDRAM.
Processing of the image stored in on-board SDRAM
Interaction with its environment for product information and
measurement results
Programming this TriMedia processor can be done using
the Rhapsody C/C++ software package or a graphical
development environment called Clicks. The TriMedia part
of this software is based on the real time operating system
pSos™. Especially for high-end vision applications this is
very important, because in this way the timing of the
application is deterministic, this in contrast to programs
running in Windows™.
Clicks allows application engineers to graphically compose
the tasks to perform. Without the need of programming
expertise this tool is easily accessible for most engineers
and offers a very natural and interactive way to realize your
application.
