Description
The SMT326 is a PC-ISA full-length card supporting a TMS320C44 ('C44) DSP together with
multiple A/D and D/A channels.
Incorporated on the card is an interface between the PC and a 'C44 communications port.
For increased processing performance, another 'C44 (or 'C40) can be added as a TIM.

Processor
The SMT326 includes a 50MHz TMS320C44 DSP. This device is connected to a TIM (Texas
Instruments Module) site via 3 communication ports (4 ports are available with a 'C44). These three
ports are also brought out to individual connectors for connection to a larger processing system. The
connectors used are compatible with a range of Sundance 'C4x products including a 4 slot PC-ISA
TIM carrier card, frame grabbers, VXI carrier card and a 'C40 TRAM.
Debugging of application software may be carried out by the connection of an XDS-510 (or
compatible) JTAG debugger. A standard JTAG header (compliant with the requirements in the 'C4x
User's Guide) is provided on the rear edge of the board.
The 'C44 processor has two separate memory busses. They are named local and global, and the
resources on the SMT326 are shared between these busses.
An upgrade to a 60MHz 'C44 is possible
This 'C44 implementation is capable of being booted from a communication port or from on board
ROM.
