Neural Networks: Simulate the working of Dynamic Fixed Point representation of the weights on hardware
Start by reading the research literature on this topic.  There's a large number of published papers that discuss how to quantize the weights or intermediate values used in deep learning.  For instance, here are a few papers:


https://arxiv.org/abs/1412.7024, https://arxiv.org/abs/1605.06402, https://arxiv.org/abs/1612.01064, https://arxiv.org/abs/1701.08978


Start by reading them, and do a literature search to identify other relevant papers (e.g., read their related work section and find other earlier papers that are relevant; find papers that cite them using Google Scholar and read them; repeat).
