Superscalar Processor Architecture and Performance Modeling for Mobile Devices

Modern mobile CPUs are superscalar, using deep pipelining, branch prediction, register renaming, out‑of‑order issue, execution, write‑back, and commit stages to boost instruction‑level parallelism, while performance modeling via CPI and hardware counters helps engineers overcome power, memory, and compiler limitations for efficient code.
