applications, we knewwe had tomake the Cortex-A32 scalable. Cortex-A32 therefore offers a wide range of configuration options. The diagram below shows two configurations of Cortex-A32 but there is a range of possibilities in between. The configuration on the left in the diagram above shows a typical performance optimized multi-core configuration - quadcore, larger cache sizes and includes optional features like NEON and Crypto engines. This configuration provides excellent performance for most rich embedded applications and retains ARM’s low power leadership - consuming less than 75mW per processor core, when running at 1.0GHz on a 28nm process node. At the other extreme, the smallest configuration of the Cortex-A32 processor, with a physical implementation optimized for area, occupies less than quarter of mm2 and consumes less than 4mW at 100MHz in the same 28nm process node. With this scalability, the Cortex-A32 is suitable for a wide range of rich embedded applications. In summary, the lowest cost rich embedded applications are about to get a lot more exciting. Cortex-A is already the number 1 CPU architecture for rich embedded. The Cortex-A32 expands the Cortex-A family and adds our most efficient 32-bit application processor yet. The Cortex-32 is set to drive future innovation in rich embedded and IoT - I can’t wait to see what our partners will build with it.
