Adaptive Noise Canceller LS Lattice Demo

Description

This adaptive noise canceller (ANC) demo presents the use of our least-square lattice (LSL) IP core. The LS lattice adaptive filter employed within the core is implemented as four-stage pipelined unit. The core operates on 16-bit two's complement integer (fixed-point) input/output data. However, the LS lattice algorithm and all other calculations are implemented in the 19-bit logarithmic number system (LNS) arithmetic. Conversions from integer to LNS representation and vice versa are integrated within the LS lattice core.

The ANC LSL demo contained in this package has been prepared for testing on two different prototyping boards:

  1. The Celoxica RC200(E) board equipped with the Xilinx Virtex-II XC2V1000-4 FPGA.
  2. The XESS XSV-800 board equipped with the Xilinx Virtex XCV800-4 FPGA.
