A table reduction technique for logarithmically architected digital filters
Matthias Frey, Fred J. Taylor · IEEE Transactions on Acoustics Speech and Signal Processing · 1985
The logarithmic number system (LNS) has been shown to offer high speed and precision metrics. Unfortunately, in practice, its precision is limited by the addressing space of high-speed semiconductor memory. An algorithm is presented which significantly reduces this memory requirement. As a result, both high speeds and precision can be obtained using the existing ECL, HMOS, or bipolar hardware.
