ARM has developed a broad range of 32-bit processors from which silicon partners can select. In 4Q12, ARM announced the first ARMv8 processor cores, Cortex-A53 and Cortex-A57, which in addition to extending the performance capabilities of ARM's 32-bit processor product portfolio are capable of running 64-bit software.
ARM's lengthy history as a supplier to the mobile market has shown that the most efficient approach is to implementing silicon devices is through the use of heterogenous processing. big.LITTLE processing describes the tight coupling of highly efficient, modest compute processor cores with higher performance processors. Transparent to the software developer, low level software such as operating systems allocate specific tasks to the processor type that best meets the performance requirements for the task. The Cortex-A53 and Cortex-A57 represents the 3rd generation of this technology.
Over the last few years, one of ARM's primary focuses has been around software. ARM formed Linaro, a not-for-profit organization, specifcally tasked with aligning the open source tools and kernel distributions across the ARM ecosystem. ARM was also responsible for establishing Trustonic, a joint venture with Gemalto and G&D, focused on estalbishing a secure root of trust on which secure applications (including mobile payments) can be developed.
