Simulink Block Library for Fast Prototyping of Reconfigurable DSP systems

This paper presents a block library for Matlab/Simulink that allows fast prototyping of reconfigurable DSP systems. Up till now no similar software package was available. The block library supports the construction of reconfigurable discrete time linear and non-linear systems from reconfigurable digital filters using various filter structures, state-space form implementations, polynomial filters, and PID controllers. The paper lists the requirements for the block library and introduces the main implementation related decisions that allows the block library to meet these requirements. An example illustrates the usage of the block library.
