2 Getting Started with the Real-Time Workshop
2-28
Targeting dSPACE
dSPACE, a company that specializes in real-time hardware and software
products, markets a complete set of tools for use with the Real-Time Workshop.
These tools are primarily intended for rapid prototyping of control systems and
hardware-in-the-loop applications. This section provides a brief example of
how to use dSPACE’s RTI (real-time interface) with the Real-Time Workshop.
The dSPACE hardware line includes DSP boards based on the Texas
Instruments TMS 320 C31 and C40 DSP’s. dSPACE boards include:
• A single processor board, the DS1102, that includes on-board I/O (A/D and
D/A conversion as well as digital I/O and encoder inputs).
• The DS1003 board based on the TI C40 DSP.
• The DS1004 based on the DEC Alpha, used for maximum throughput.
For a current summary and more information on dSPACE products and their
relationship to the Real-Time Workshop, refer to the documentation provided
by dSPACE or contact your dSPACE distributor.
At present, all dSPACE boards conform to the half length or full length ISA slot
size. The ISA slot enables the host PC to download the executable to a dSPACE
target processor board at a higher bandwidth than is possible over the ISA
backplane. dSPACE boards utilize the proprietary PHS bus; this bus lets the
dSPACE processor board(s) communicate with other dSPACE I/O boards.
Multiprocessor and multi-I/O boards are common. One exception is that the
DS1102 is for use as a single board solution with its own on-board I/O. The ISA
bus is also used for downloading new block diagram parameters and for
passing collected data back to the host computer.
The dSPACE product line includes a variety of A/D and D/A boards, encoder
boards, and digital I/O boards. A hardware prototyping board gives you the
ability to interface your own hardware directly with the dSPACE hardware.
You can use all these products in combination with code generated by the
Real-Time Workshop.

PC chassis and the dSPACE PHS bus:
