"User" Hardware Architecture Manual and "User" Software Development Manual

I am currently working on an implementation of deep learning image recognition. I want to understand how the CPU calls the GPU to perform operation identification and return data to the CPU.
CPU Specification: Intel ® Core ™ i7-8700 CPU@3.20GHz 3.19GHz
GPU model: MS-V328 (Nvidia GeForce GTX 1060 6gb)
I would like to ask if there is a “user” hardware architecture manual and a “user” software development manual and sample programs for user reference?
Thanks ~
