ABSTRACT:
A method of reducing the power consumption of microprocessor system is provided, wherein: said microprocessor system comprises a microprocessor (2) and a memory (4) connected by a bus (6); said memory (4) contains a plurality of data values, each represented by a number of bits, for transmission to said microprocessor (2) via the bus (6); and at least some of said data values contain unused bits; and wherein said method includes assigning values to said unused bits in such a way as to reduce the Hamming distance between successive data values by a greater extent than setting all of said unused bits to an arbitrary predetermined value.
