Decimal/rf_.sidue/decimal Optical Converters
Residue arithmetic [1-3] appears to be an attractive scheme for realizing a high speed numerical processor. Huang [4,5 ] was one of the first to suggest fabrication of an optical residue arithmetic processor. One recent optical approach [6] to such a system uses ~he phase or polarization of a spatial point as the cyclic variable. Another approach [7] uses pulse-position modulation to represent ...
متن کاملDecimal Codes
To make error correcting codes easier to use and analyze, it is necessary to impose some algebraic structure on them. It is especially useful to have an alphabet in which it is possible to add, subtract, multiply and divide without restriction. In other words we wish to construct a finite field. Evarist Galois (1811-32), a French mathematician who died in a duel at the age of 20 introduced fini...

specialist microfinance institutions (MFIs). The Central Bank of Sri Lanka (CBSL) has traditionally pursued an active "developmental" role in the microfinance sector, although this has been changing. It should further reduce its developmental activities by diluting its ownership of regional development banks and taking a less hands-on role in project implementation. Conversely, it would be appr...
متن کاملCorrectly Rounded Binary-Decimal and Decimal-Binary Conversions
This note discusses the main issues in performing correctly rounded decimal-to-binary and binary-to-decimal conversions. It reviews recent work by Clinger and by Steele and White on these conversions and describes some efficiency enhancements. Computational experience with several kinds of arithmetic suggests that the average computational cost for correct rounding can be small for typical conv...
متن کاملIntroduction to Decimal Sequences
A decimal sequence is obtained when a number is represented in a decimal form in a base r and it may terminate, repeat or be aperiodic. For a certain class of decimal sequences of q 1 , prime, the digits spaced half a period apart add up to q 1 − r , where r is the base in which the sequence is expressed. Decimal sequences are known to have good crossand auto-correlation properties and they can...
