We close the series with RISC and CISC, performance metrics, Flynn’s taxonomy, SMP, clusters, NUMA, multicore, and Amdahl’s Law. https://cienciaprogramada.com/2026/04/cpu-components-instruction-cycle/ Thu, 16 Apr 2026 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2026/04/cpu-components-instruction-cycle/ A 2 GHz processor can execute more instructions per second than a 3 GHz one. To understand why, we open up the CPU: ALU, control unit, registers, flags, decoder, and clock, along with the microevents of the fetch cycle in formal notation.
