1. Apparatus for data processing, said apparatus comprising:
- (i) M X-bit registers, where M is a positive integer greater than 1, for receiving respective input operand data words from a data storage device;
(ii) an arithmetic logic unit for performing arithmetic logic operations upon said input operand data words stored in said X-bit registers to generate output data words;
(iii) N Y-bit registers, where N is a positive integer greater than 1, for receiving said output data words from said arithmetic logic unit;
(iv) wherein M/N=3, 8≦
Y-X <
16 and 3X=2Y.

Abstract
A data processing system is provided including an arithmetic logic unit 20, 22, 24 receiving input operands from M X-bit registers to produce output data words stored within N Y-bit registers, where M/N=3, 8≦Y-X≦16 and 3X=2Y. This arrangement is particularly suited for digital signal processing and in situations where each input operand is used a plurality of times before a new input operand is loaded in its place in a register.
