Widely Deployed Multicore Processor
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. A multicore processor optimized for performance and power, Cortex-A9 is one of the most widely deployed and mature applications processors from Arm. It is suitable for low-power, cost-sensitive, 32-bit devices that require competitive performance.
Available in two variants, Cortex-A9 provides maximum flexibility. You can use it as a single core Cortex-A9 UP processor, or in a cluster of up to four processors for a broad range of 32-bit applications.
All Cortex-A processors share a commonly supported architecture and feature set and are backed by a strong Arm ecosystem. Armv7-A processors support a 32-bit instruction set and data path, as well as the mixed 16/32-bit Thumb2 instruction set.
Mature and silicon proven in multiple process technologies, Cortex-A9 offers reliable performance powered by a dual-issue superscalar and out-of-order architecture.
Mali-470
The Mali-470 is the first GPU designed specifically for the power-sensitive requirements of wearable and IoT devices. It delivers superior energy efficiency across one to four core implementations, reducing the cost of both implementation and operation.
CoreLink CCl-400
The Arm CoreLink CCI-400 Cache Coherent Interconnect provides full cache coherency between two clusters of multi-core CPUs. It enables big.LITTLE processing and I/O coherency for devices such as the Mali-T600 series GPU, and I/O masters like modem and USB.
POP IP
POP IP is the bridge between Cortex-A CPU and silicon process technology. A highly optimized physical IP solution for Cortex-A processors, the Artisan POP IP delivers a proven high-performance or high-density implementation solution while lowering technical and project risk.
Arm-based chips, device architectures, and technologies orchestrate the performance of everything that makes modern life possible — from smartphones to agricultural sensors and from medical instruments to servers.
Armv7-A Architecture
The Armv7-A architecture introduced the concept of architecture profiles. It implements a traditional Arm architecture with multiple modes, supports a virtual memory system architecture (VMSA) based on a memory management unit (MMU), and supports the Arm (A32) and Thumb (T32) instruction sets.
TrustZone
Arm TrustZone technology provides system-wide hardware isolation for trusted software. The family of TrustZone technologies integrates into any Arm Cortex-A core, supporting high-performance applications processors.
