App Profile: CPU DasherX

CPU DasherX is a sophisticated app that contains 140,000 lines of assembly code and over 30,000 Objective-C code to provide nice user experience, accurate CPU frequency and the best CPU performance, without any memory leak or crash. It contains no 3rd party libraries, no ads, no file-writing operations. It does not connect to the network. It provides pure and green functionalities so that it is safe and energy efficient.

It is a smart app that shows a lot of information in 64-bit mode for Apple A7 or later processors. It lists the device info, CPU info, almost all the 64-bit ARM instruction set(including general-purpose instructions and SIMD & VFP instructions) and the performance of several common algorithms, such as matrix multiplication, sum of an array, color-to-gray image processing algorithm and image convolution algorithm.
CPU DasherX evaluate the execution performance not only via CPU, but also via GPU with the most advanced Metal API. Each algorithm optimization is sophisticated and elaborate. They will demonstrate how well your current device can perform and you can use specific strategy on different devices when you're making an amazing app.
