Abstract

It is disclosed a method for implementing an Instruction Set Architecture (I) for a Central Processing Unit (50). The method comprises the step a) of providing a plurality of instructions (RR, RI, RRc, J, JR, B, MV, WFI, BKPT, LI, L/LB/S/SB, CA, PP) to be executed by the Central Processing Unit, each instruction comprising at least sixteen bits, comprises the step b) of arranging at least part of said plurality of instructions into a plurality of instructions formats (RR/RI; J/JR/MV/WFI/BKPT/LI; LB/PP; RRc/L), wherein the number of the plurality of instructions formats is less than the number of the plurality of instructions, and comprises the step c) of assigning, in the plurality of instructions formats, a corresponding value of a first field composed of three bits (#7, #6, #5), selected from the at least sixteen bits, for identifying a respective instruction format (RR; J/JR/MV/WFI/BKPT/LI; LB/PP; RRc/L) out of said plurality of instructions formats.
