The ARM Cortex-A15 MPCore is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. It is a multicore processor with out-of-order superscalar pipeline running at up to 2.5 GHz. [6]
ARM has claimed that the Cortex-A15 core is 40 percent more powerful than the Cortex-A9 core with the same number of cores at the same speed. [7] The first A15 designs came out in the autumn of 2011, but products based on the chip did not reach the market until 2012. [1]
Key features of the Cortex-A15 core are:
First implementation came from Samsung in 2012 with the Exynos 5 Dual, which shipped in October 2012 with the Samsung Chromebook Series 3 (ARM version), followed in November by the Google Nexus 10.
Press announcements of current implementations:
Other licensees, such as LG, [22] [23] are expected to produce an A15 based design at some point.
