The apple A7 is a 64 bit chip designed by apple which means it’s the worse on the market despite being the first chip to be readily available to consumers. It’s a 1.3 – 1.4 GHz ARMv8-A dual core CPU called Cyclone. The A7 has a per core L1 cache of 64 KB for data and 64 KB for instructions, a L2 cache of 1 MB shared by both cores, and a 4 MB L3 cache that service the entire SoC. It’s used in the IPhone 5S, IPad Mini 2 and 3. An ARM processor is one of a family of CPUs based on the RISC (reduced instruction set computer) architecture developed by Advanced RISC Machines (ARM). They are extensively used in consumer electronic devices such as smartphones, tablets, multimedia players and other mobile devices, such as wearables. Because of their reduced instruction set, they require fewer transistors, which enables a smaller die size for the integrated circuitry (IC). The ARM processor’s smaller size, reduced complexity and lower power consumption makes them suitable for increasingly miniaturized devices.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
