Here's the link to the paper, which you've linked to on the resources
page. I just thought I'd include it in this bug/mailing list for ease of
access: "Low Latency and Low Error Floating-Point Sine/Cosine Function
Based TCORDIC Algorithm" (https://ieeexplore.ieee.org/document/7784797).
For project members that do not have IEEE explore access, please email
Michael or myself off-list.

I also think that this paper may be relevant, however, I am not entirely sure.
"Pipelined Range Reduction Based Truncated Multiplier"
(https://ieeexplore.ieee.org/document/9062697).
