The ARM Cortex-A5 processor is the smallest, lowest cost and lowest power ARMv7 application processor.
As a standalone processor, it is capable of delivering the internet to the widest possible range of devices, from smart devices like wearable, feature phones and low-cost, entry-level smartphones, to a range of pervasive embedded, consumer and industrial devices.
The Cortex-A5 processor is supported by a suite of optimized IP targeted at mid-range solutions, bringing highest efficiency levels and ease of integration. ARM Mali™-400 provides support for 2D vector graphics through OpenVG™ 1.1 and 3D graphics through OpenGL® ES 1.1 and 2.0, while ARM Physical IP Platforms deliver process optimized IP, for best-in-class implementations of the Cortex-A5 processor at 40nm and below.
The ARM Cortex-A9 processor is a popular general purpose choice for low-power or thermally constrained, cost-sensitive devices.
The processor is a mature option having been introduced in 2008, and remains a very popular choice in smartphones, digital TV, and both consumer and enterprise applications enabling the Internet of Things. As a single processor solution, the Cortex-A9 processor offers an overall performance enhancement of well above 50% compared to ARM Cortex-A8 solutions.
The Cortex-A9 processor is available with a range of supporting ARM technology. ARM Physical IP is available to support a synthesizable flow optimized for lowest power or highest performance, as well as a choice of hard-macros reducing risk and shortening time-to-market. Enhanced ARM Graphics IP like Mali™-T624 and ARM System IP such as CoreLink™ NIC-400/301 network interconnect and CoreLink DMC-342 dynamic memory controller allow a rapid system design.
