Abstract
We present the first fully-integrated universal Max-
imum Likelihood decoder in 40 nm CMOS using the Guessing
Random Additive Noise Decoding (GRAND) algorithm for low-
power applications. The 0.83 mm2 multi-code multi-rate universal
decoder can efficiently decode any code of length up to 128 bits
with 1 μs latency at 68 MHz. Dynamic clock gating leveraging
noise statistics reduces the average power dissipation to 3.75 mW
at 1.1 V or 30.6 pJ/decoded bit with a throughput of 122.6 Mb/s.
Universal decoding reduces hardware footprint, and the design
allows seamless swapping between codebooks with no downtime,
enabling use by multiple applications without switch-over.
