Smallest Processor for 32-Bit
The Arm Cortex-A processor series is designed for devices undertaking complex compute tasks, such as hosting a rich operating system platform and supporting multiple software applications. Cortex-A32 is a low-power 32-bit only processor with ultra-high efficiency, suitable for the diverse embedded and IoT markets.
Features and Benefits
Idle power management features introduced in Cortex-A32 reduce leakage power in the CPU idle states, making it suitable for long periods of inactivity. It is the most efficient Arm processor and achieves low dynamic power in CPU active states.
This processor can be used in different configurations, from a single core to a maximum of four CPU cores in a cluster, providing flexible options for designers and scalability for diverse embedded applications.
Armv8-A architecture in Cortex-A32 is compatible with existing Armv7-A 32-bit software and provides enhanced floating performance for media and video applications. It also delivers substantially faster software encryption for increased security.
Where Innovation and Ideas Come to Life
Low-Power IoT Nodes
Energy-harvesting wireless sensor nodes use ambient energy as a power source where batteries or cables are not viable. When those nodes also need to support a rich operating system, Cortex-A32 provides the processing power needed, combined with superior energy efficiency and built-in TrustZone security.
Embedded Applications
Rich-embedded applications require virtual memory and memory management, and often need high performance within a low power budget.
Artificial Intelligence and Machine Learning
Artificial intelligence (AI) and machine learning (ML) are expanding and defining more applications than ever before, changing how we interact with devices and machines everywhere. Arm CPU processor IP is scalable and flexible enough to run any type of ML workload, today or in the future.
