ARM introduced the Cortex-A5 MPCore processor, claiming this is the most power-efficient and cost-effective multicore processor for Internet-capable low-cost phones, smartphones and other mobile devices.
Available as an extremely area- and power-efficient uniprocessor or up to a 4x multicore processor, the Cortex-A5 processor unleashes the outstanding performance and power scalability required for the compelling usage scenarios demanded by each of these markets. This extraordinary combination of performance, functionality, and efficiency reinforces ARM’s clear leadership position in the highest-value and highest-volume application segments.
The Cortex-A5 uniprocessor provides a high-value migration path for the large number of existing ARM926EJ-S™ and ARM1176JZ-S™ processor licensees. By delivering better performance than the ARM1176JZ-S processor within the raw power and silicon area footprint of the ARM926EJ-S processor, the Cortex-A5 uniprocessor offers nearly twice the power-efficiency relative to these earlier and extremely popular predecessors. This increases the quality of the user experience while reducing costs and end-user device size.
This performance is further enhanced by the Cortex-A5 multicore processor which utilizes the successful ARM MPCore technology. The widely-adopted ARM MPCore technology increases performance scalability and control over power consumption to exceed the performance of today’s comparable high-performance devices while remaining within the tight mobile power constraints. To date ARM MPCore processors have been licensed by more than 15 leading semiconductor companies including Broadcom Corporation, NEC Electronics (Europe) GmbH, NVIDIA, Renesas Technology America, Inc., Toshiba America Electronic Components and Sarnoff Corporation, and have been implemented in numerous applications on the market today. This technology greatly expands the addressable application spectrum while enabling new and more efficient modes of operation.
The Cortex-A5 processor includes TrustZone® security technology along with a NEON™ multimedia processing engine first introduced with the Cortex-A8 processor. NEON technology is a 128-bit SIMD (Single Instruction, Multiple Data) architecture extension for the Cortex-A series processors, providing flexible and compelling acceleration for intensive multimedia applications.
The Cortex-A5 processor is fully application compatible with the Cortex-A8 and Cortex-A9 processors. This enables immediate access to an established developer and software ecosystem including Android, Adobe Flash, Java Platform Standard Edition (Java SE), JavaFX, Linux, Microsoft Windows Embedded, Symbian and Ubuntu, along with more than 600 ARM Connected Community™ members.
