<p>In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.</p><p>The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.</p><p>A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution.</p>
