The Cortex-M55 is a synthesizable ultra-low-power core designed by [[Arm]] for an array of applications such as microcontrollers and embedded subsystems doing background work on more performant SoCs. Successionally and architecturally, the Cortex-M55 is the successor to the {{\\|Cortex-M7}} and the {{\\|Cortex-M4}}, although in purely raw performance it's slightly behind the M7, though it makes up for it in new technologies such as its {{arm|Helium|new vector extension}}. The Cortex-M55 is said to deliver 1.6 [[Dhrystone DMIPS/MHz]] and 4.2 [[CoreMark/MHz]] which is about 25% higher than the {{\\|Cortex-M4|M4}} but about 20% lower than the {{\\|Cortex-M7|M7}}. In terms of frequency, the M55 is said to deliver up to 15% higher clock speed over the {{\\|Cortex-M4|M4}}. | The Cortex-M55 is a synthesizable ultra-low-power core designed by [[Arm]] for an array of applications such as microcontrollers and embedded subsystems doing background work on more performant SoCs.
