Abstract

An example of an application-specific core is described, which embodies domain specific knowledge in with the construction of parameterizable circuit. Application-specific cores present a more familiar interface to the end user, since parameters are now domain-specific rather than core-specific. A FIR filter is described, which is parameterizable at run-time by its desired frequency response. The core can calculate its own weights, and a configuration datastream suitable for downloading to a programmable device in a matter of seconds, opening up a new realm of testing, both at the core level and at the system level.
