Subject: [libre-riscv-dev] [Bug 208] implement CORDIC in a general way sufficient to do transcendentals
Date: Thu, 16 Apr 2020 15:36:03 +0000
Message-ID: <bug-208-13-wZsoRd0Waz@https.bugs.libre-soc.org/> (raw)

--- Comment #17 from Michael Nolan <mtnolan2640@gmail.com> ---
I'm working on converting the floating point input to the fixed point value
needed by the cordic. I've got my module decoding the float into sign,
exponent, and mantissa with FPNumDecode, and the mantissa is missing the
(implied) leading 1 bit. I'm also looking at the modules of fpdiv (div0.py and
nmigen_div_experiment.py), and they don't seem to add that bit back in. Is
there a way to have FPNumDecode generate a mantissa with the leading 1 bit?
