    Cortex_DFP

A highly power efficient mid-range application CPU built on Arm DynamIQ technology.
The Arm Cortex-A55 processor is a CPU that delivers a combination of power efficiency and performance. The processor is part of the first generation of application CPUs based on DynamIQ technology and features the latest Armv8-A architecture extensions, with dedicated machine learning instructions. The Cortex-A55 incorporates an extensively redesigned microarchitecture system that improves performance across the board while being very competitive in area and power efficiency. It delivers up to 18% more performance at 15% better power efficiency when compared to its predecessor, the Cortex-A53. Designed to be an extremely scalable CPU, the versatile Cortex-A55 can be used to address a wide range of applications with diverging cost, from the edge to the cloud. The Cortex-A55 can be implemented in both stand-alone applications or as a ‘LITTLE’ CPU to the Cortex-A7x series with DynamIQ big.LITTLE.
