WebSep 25, 2024 · It's certainly meaningful to talk about instruction fetch latency. That's part of branch latency: cycles until useful instruction bytes arrive after a branch changes PC. (Without branch prediction, there's AFAIK no attempt to hide that latency in a simple pipeline like Cortex-M3. That's what makes taken branches cost extra cycles.) – WebMar 21, 2016 · The Armv6-M architecture covers the Cortex-M0, Cortex-M0+ and Cortex-M1 processors, and Armv7-M architecture covers the Cortex-M3, Cortex-M4 and Cortex-M7 processors.
