    The traditional approach to IP core design is to use simulations with test vectors. This is not feasible when dealing with complex function cores such as the Image Segmentation case-study algorithm in this paper. An algorithm developer needs to carry out experiments on large real-world data sets, with fast turn-around times, and in real time to facilitate performance tuning and incremental development. Previously we proposed a methodology called Application-Specific Vector Processor (ASVP). The ASVP approach first constructs a programmable architecture customized for a given application, then employs software techniques to develop firmware that implements the algorithm. In our setting we employ an embedded simple scalar CPU (8-bit PicoBlaze 3) to control a floating-point vector processing unit (VPU) by issuing wide (horizontally encoded) instructions to it. In this work we dramatically reduce the overhead of the wide-instruction issue (in one case by 13x) by implementing a new two-level configuration table.
