The Multiple-Wordlength Operation Grouping (MWOG) is a recently used approach for an optimized implementation on a Field Programmable Gate Array (FPGA). By fixing the precision constraint, this approach allows minimizing the data wordlength. In this paper, the authors present the integration of the approach based on the MWOG in the Algorithm Architecture Adequation (AAA) methodology, designed t...

Minimum aberration designs are obtained for two types of mixed-level fractional factorial: (i) (s) × s factorial, and (ii) (s1) × (s2) × s factorial, where s is any prime or prime power, and r, r1, r2 and n are positive integers. Projective geometric tools are employed to find the wordlength pattern of a given design in terms of that of its complementary set. Many useful designs are found

This utility software automatically converts a oating-point digital signal processing program written in C or C++ language to a xed-point program. The conversion is conducted by deening a new xed-point data class and utilizing the operator overloading characteristic of the C++ language. A generalized xed-point format which consists of the wordlength, integer wordlength, sign, overrow, and quati...

This note discusses the multiple wordlength assignment problem for the design of custom digital signal processing (DSP) parallel processors. It is demonstrated that this assignment problem is NP-hard. @ 2002 Elsevier Science Ltd. All rights reserved.

Factorial designs are arguably the most widely used designs in scientific investigations. Generalized minimum aberration (GMA) and uniformity are two important criteria for evaluating both regular and non-regular designs. The generation of GMA designs is a non-trivial problem due to the sequential optimization nature of the criterion. Based on an analytical expression between the generalized wo...
