Is Cortex-A7 good?
The sweet spot of maximum performance at sub 100mW power per core makes Cortex-A7 an ideal solution for use as standalone application processor, delivering excellent performance at very low power, area and cost while enabling new features to be supported in these low cost smartphone segments.
What is Armhf?
armhf stands for “arm hard float”, and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support. On the beaglebone black, for example: :~$ dpkg –print-architecture armhf. Although other commands (such as uname -a or arch ) will just show armv7l.
Is Cortex-A9 64-bit?
The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set.
What is Dhrystone power?
Dhrystones. Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984. This benchmark is used to measure and compare the performance of different computers or, in this case, the efficiency of the code generated for the same computer by different compilers.
