We present an implementation of a complete RLS lattice and normalised RLS lattice cores for Virtex. The cores accept 24-bit fixed point inputs and produce 24-bit fixed point prediction error. Internally, the computations are based on 32-bit logarithmic arithmetic. On Virtex XCV2000E6, it takes 22% and 27% of slices respectively and performs at 45 MHz. The cores outperform (4-5 times) the standard DSP solution based on 32-bit floating point TMS320C3x/4x 50 MHz processors. (8 References).
