Abstract
In this paper we describe a framework that constructs
interfaces between simulation tools and real-time prototyping
hardware in a high-level DSP synthesis environment. A goal of this
work is to abstract the concept of the interface so that customized
links are not required between each simulation and hardware
engine. To support a new engine, the DSP system designer must
define two pairs of communication primitives between the new tool
and host workstation. The interface construction mechanism
provides incremental compilation of subsystems in a system
specification into the high-level DSP synthesis environment. We
illustrate this framework with practical examples that have been
constructed in Ptolemy.
