The FlashLinQ and Lycan modems employ FIR filters within the signal processing blocks. New techniques developed by the ALGOS group can optimize these filters if they use constant multiplications. These algorithms maximize the sharing of partial terms hence yielding significant area reductions. Initial experiments on low-pass filters within the RL Sample Rate block in FlashLinQ showed area reductions of approximately 24%.

INESC-ID will provide engineering services to analyze and design alternate FIR filter structures that will further reduce area. Specifically, within the RL Sample Rate block logic is shared between the I and Q paths of the filters. INESC-ID will generate RTL code for these alternate structures that Sponsor can use in the RL Sample Rate blocks in order to estimate area savings.
