Systems and methods for lookahead instruction fetching for processors utilizing tagless hit instruction caches

Systems and methods may be provided for lookahead instruction fetching for processors. The systems and methods may include an L1 instruction cache, where the L1 instruction cache may include a plurality of lines of data, where each line of data may include one or more instructions. The systems and methods may also include a tagless hit instruction cache, where the tagless hit instruction cache may store a subset of the lines of data in the L1 instruction cache, where instructions in the lines of data stored in the tagless hit instruction cache may be stored with metadata indicative of whether a next instruction is guaranteed to reside in the tagless hit instruction cache, where an instruction fetcher may be arranged to have direct access to the L1 instruction cache and the tagless hit instruction cache, and where the tagless hit instruction cache may be arranged to have direct access to the L1 instruction cache.
