Title:
PROCESSOR AND METHOD FOR SIMULTANEOUSLY DOING A CALCULATION AND CARRYING OUT A COPYING PROCESS
Document Type and Number:
WIPO Patent Application WO2003104975
Kind Code:
A3
Abstract:
Disclosed is a processor comprising a source register (10) with a content, a destination register (12), an arithmetic unit (14) doing a calculation by using the content of the source register, said calculation being done in several cycles and only a portion of the content of the source register being usable in each cycle, a data bus (18) which is connected to the source register (10), the destination register (12), and the arithmetic unit (14), and a processor control unit which is operable so as to feed the content of the source register in portions to the arithmetic unit and the destination register via the data bus during the calculation process such that the content of the source register is written in the destination register once the calculation is done. The inventive processor makes it possible to copy a register for long operands that are to be processed portion by portion from a source register to a destination register via a limited data bus without using any additional machine cycles.
