Comments on Duprat and Muller's Branching CORDIC Paper
نویسنده
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...
متن کاملDouble 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...

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.

متن کاملAnalytical 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...
متن کاملDesign and Implementation of Digital Demodulator for Frequency Modulated CW Radar (RESEARCH NOTE)
Radar Signal Processing has been an interesting area of research for realization of programmable digital signal processor using VLSI design techniques. Digital Signal Processing (DSP) algorithms have been an integral design methodology for implementation of high speed application specific real-time systems especially for high resolution radar. CORDIC algorithm, in recent times, is turned out to...
