Abstract

Some implementations disclosed herein provide techniques and arrangements for indicating a length of an instruction from an instruction set that has variable length instructions. A plurality of bytes that include an instruction may be read from an instruction cache based on a logical instruction pointer. A determination is made whether a first byte of the plurality of bytes identifies a length of the instruction. In response to detecting that the first byte of the plurality of bytes identifies the length of the instruction, the instruction is read from the plurality of bytes based on the length of the instruction.
