Dec 31, 17 · Cortex M4 has Run , Sleep and Deep sleep modes – True / False ?Singlecycle I/O – it's possible to bitbang the pins really fastCortexR Ideal for safetycritical applications Safety features • Supports Lockstep • Memory Protection Unit (MPU) • ErrorCorrecting Code (ECC) Higher performance • 8stage processor pipeline • Dual issue – two instructions can execute in parallel • Load store unit reduces stalling • Prefetch and Branch Prediction Units

Ie, there is no pipeline difference on the CortexM4 "Learn something" result (consistent with my previous claims but not my expectations) For cases where N>0, one cycle fewer will be measured in sequences using NOP than in sequences using MOV R8,R8Jan 21, 17 · According the the M4 technical reference manual "For ISB, the minimum number of cycles is equivalent to the number required for a pipeline refill" Quite why this is 4 cycles and not 3 I am unsure, it is possibly something to do with ensuring the branch prediction logic is correctIs 32pin Cortex M4 compatible with 256 pin Cortex M4 processor ?
