Abstract

A new vector arithmetic coprocessor MIM XPA3233 with integrated PCI bus interface has been developed in CMOS VLSI technology. The chip performs dot products of vectors with components of the IEEE DOUBLE data format to full accuracy or with only one final rounding. Details on the realisation of the multiplication, accumulation and carry resolution processes are discussed. Performance data and some details about the actual VLSI realisation are presented. Software support for the coprocessor is available in the programming languages PASCAL-XSC and C-XSC or from a special C subroutine library. Programming examples are shown using PASCAL-XSC and C
