A primer on binary-arithmetic rounding -  01/21/99 EDN-Design Ideas -   (Scroll to find this one)  As digital communications and data compression/decompression proliferate, signal-processing functions grow in importance.  Whether you’re dealing with hard-wired logic or programmable engines, an understanding of binary-arithmetic rounding is important in getting correct and consistent results.  Before we discuss rounding, consider a binary number  (Figure 1) Page includes several designs.  __ Circuit Design by Tom Balph, Motorola SPS, Tempe, AZ

Fast Integer Multipliers Fit In FPGA -  05/12/94 EDN-Design Ideas You can fit a fast and compact digital multiplier into a field-programmable gate array(FPGA].  The technique involves using small look-up tables to find partial products and then adding the partial products.  The key factor for making the design compact, fast, and easy to implement is to make the look-up tables for the partial products as small as possible.  This multiplier can quickly multiply a number by a constant; changing the constant momentarily takes the multiplier off-line__ Circuit Design by Kenneth David Chapman, Xilinx Ltd, byfleet, Surrey, UK
