It’s time to make your smart wearables and other smart devices even smarter as ARM is introducing its smallest ARM Cortex A-32 processor targeting next generation wearables, Internet of Things (IoT), embedded systems and low-cost boards like Raspberry Pi or Pi Zero. Using the ARMv8 instruction set it is intended as a replacement for the older Cortex A7 and A5 architectures (both using the ARMv7 instruction set).
Having 70 percent market share in embedded, or processors used in machinery-like devices such as automobiles, ARM is locating itself to extend that share with a focus on the IoTs that market researcher IDC thinks could be a $1.7 trillion market by 2020.
To save space and power, the ARM Cortex A-32 can only run 32-bit code, ARM’s first processor that doesn’t include 64-bit support. However, the new ARMv8 instructions still give the A32 a better performance boost over the Cortex A5 and A7, especially in cryptography performance. If you still want the 64-bit support, the Cortex A-35 is offering similar performance with 64-bit instructions in a bit larger package. However, A-32 is about 10 percent faster than A-35 in 32-bit operations, according to ARM.
ARM says the new chip brain is about 25 percent more efficient than the Cortex A7, thanks to a combination of reductions in power consumption and speed improvements. Like the other ARM processors, the new A-32 is scalable for a large manner of embedded applications. It is also optimized for efficiency and low cost and has built-in security as well.
