Google further added that this competency of Image Processing Unit is attained because of tight coupling of hardware and software. The software controls the hardware in a better manner which in turn results in making the hardware less complicated and more effective. Also, instead of using conventional programming language, domain specific language is used for programming IPU. Halide is used image processing and Tensor Flow for machine learning.
