Feature detection and matching on an SIMD/MIMD hybrid embedded processor

This work presents the implementation of a feature detection and matching algorithm on an innovative SIMD/MIMD dynamically-reconfigurable architecture intended for high-performance embedded vision systems. An FPGA-based system-on-chip with a 128-unit coprocessor running at 150 MHz is able to locate a target in 320 × 240 px images in less than 1 ms. It is also shown how to map the algorithms to speedup the processing taking advantage of the different available computation modes.
