ABSTRACT:
A processing system for executing instructions comprises a first part (11) having address information and a plurality of data bits, E0to EN. According to one embodiment, each data bit E0to ENdirectly selects a corresponding element 130to 13Nforming a second part of the instruction set (for example a VLIW). In this manner, the first part (11) is used to only select elements that do not comprise NOP instructions, thereby avoiding power being consumed unnecessarily. According to an alternative embodiment, different groups of elements in the second part (13) may be selected by a number encoded in the first part (11), using data bits Eoto EN. Preferably, these different groups reflect the most likely used combinations in a program.
