We present a custom processor that was designed to enhance algorithms of finding Low Autocorrelation Binary Sequences (LABS). Finding LABS is very computationally exhaustive, but no custom computing solutions have been reported in the literature so far. A computational kernel which allowed creating an effective single-purpose processor was determined and an appropriate architecture was proposed. The selected elements of the architecture were coded in High-Level Synthesis (HLS) language to speed up the design process. Afterwards, the processor was verified and tested in Xilinx’s Virtex7 FPGA. At the beginning of the paper, we briefly present the finding LABS problem and its importance. Later, we deliver the algorithm, its custom processor structure, and implementation results in terms of the processor performance, size and power.
