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 enormous design area for efficient options.
Presently, present DNN accelerators want assist in attaining an optimum steadiness 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 methodology 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) strategy 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 embody 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 entails assessing MC, power consumption, and delay via an Evaluator module.
The structure side of Gemini offers 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 vital enhancements with solely a marginal enhance in MC, demonstrating its effectiveness in co-exploring the structure and mapping area.
In conclusion, the Gemini framework affords a complete answer to the intricate challenges of designing DNN chiplet accelerators. The experiments not solely validate Gemini’s effectiveness but additionally make clear the potential advantages of chiplet know-how in structure design. General, Gemini stands out as a helpful software for researchers and practitioners aiming to design high-performance and energy-efficient DNN accelerators.
