Researchers from a number of universities have addressed the problem of designing large-scale DNN chiplet accelerators, specializing in optimizing financial price (MC), efficiency, and power effectivity. The complexity arises from the interaction of assorted parameters, together with network-on-chip (NoC) communication, core positions, and totally different DNN attributes. It’s essential to discover an unlimited design area for efficient options.
At present, present DNN accelerators want assist in reaching an optimum stability between MC, efficiency, and power effectivity. They launched the structure and mapping co-exploration framework for DNN chiplet accelerators, Gemini. Gemini employs a novel encoding technique to outline low-power (LP) spatial mapping schemes, permitting for an exhaustive exploration of hidden optimization alternatives. The framework makes use of a dynamic programming-based graph partition algorithm and a Simulated-Annealing-based (SA-based) method for optimization.
Gemini’s mapping part makes use of the SA algorithm with 5 operators tailor-made to effectively discover the LP spatial mapping area. These operators embrace modifying partition attributes, swapping cores inside computational teams (CG), and adjusting DRAM-related attributes. The framework dynamically optimizes knowledge transmission, intra-core dataflow, and D2D hyperlink communication, contributing to enhanced efficiency and power effectivity. The analysis course of includes assessing MC, power consumption, and delay via an Evaluator module.
The structure side of Gemini supplies a extremely configurable {hardware} template, enabling exact evaluations for efficiency, power, and MC. The proposed framework’s experiments showcase that the explored structure and mapping scheme outperforms present state-of-the-art (SOTA) designs like Simba with Tangram mapping. Gemini additionally achieves important enhancements with solely a marginal improve in MC, demonstrating its effectiveness in co-exploring the structure and mapping area.
In conclusion, the Gemini framework gives a complete answer to the intricate challenges of designing DNN chiplet accelerators. The experiments not solely validate Gemini’s effectiveness but in addition make clear the potential advantages of chiplet expertise in structure design. General, Gemini stands out as a beneficial software for researchers and practitioners aiming to design high-performance and energy-efficient DNN accelerators.
