Comments on Duprat and Muller's Branching CORDIC Paper

نویسنده

  • Dhananjay S. Phatak
چکیده

In [1], Duprat and Muller introduced the ingenious “Branching CORDIC” algorithm. It enables a fast implementation of CORDIC algorithm using signed digits and requires a constant normalization factor. This correspondence corrects some errors in the original paper. All the page numbers quoted are from [1].

Comparison of Branching CORDIC Implementations

In this paper we compare implementations of Duprat and Muller’s Branching CORDIC and Phatak’s Double Step Branching (DSB)–CORDIC algorithms for Sine and Cosine evaluation. For reference we also report on classical CORDIC implementations for the same wordlengths. We have also implemented Double Stepping in the classical algorithm and report on the performance of this method. CORDIC evaluation of...

Double Step Branching CORDIC: A New Algorithm for Fast Sine and Cosine Generation

Duprat and Muller [1] introduced the ingenious “Branching CORDIC” algorithm. It enables a fast implementation of CORDIC algorithm using signed digits and requires a constant normalization factor. The speedup is achieved by performing two basic CORDIC rotations in parallel in two separate modules. In their method, both modules perform identical computation except when the algorithm is in a “bran...

Muller's Nobel Prize Lecture: when ideology prevailed over science.

This paper extends and confirms the report of Calabrese (Calabrese, E. J. (2011b). Muller's Nobel Lecture on dose-response for ionizing radiation: Ideology or science? Arch. Toxicol. 85, 1495-1498) that Hermann J. Muller knowingly made deceptive comments in his 1946 Nobel Prize Lecture (Muller, H. J. (1946). Nobel Prize Lecture. Stockholm, Sweden.

Analytical results on Muller's ratchet effect in growing populations.

Fontanari introduced [Phys. Rev. Lett. 91, 218101 (2003)] a model for studying Muller's ratchet phenomenon in growing asexual populations. They studied two situations, either including a death probability for each newborn or not, but were able to find analytical (recursive) expressions only in the no-decay case. In this Brief Report a branching process formalism is used to find recurrence equat...
