INTIACC: A Programmable Floating-Point Accelerator for Partial Differential Equations
INTIACC: A Programmable Floating-Point Accelerator for Partial Differential Equations 150 150
Author(s): Paul Xuanyuanliang Huang, Yannis Tsividis, Mingoo Seok

Abstract:

This article presents a 32-bit floating-point (FP32) programmable accelerator for solving a wide range of partial differential equations (PDEs) based on numerical integration methods. Compared to prior works that have fixed-point systems and are only applicable to specific types of PDEs, our proposed, integration accelerator for PDEs, named INTIACC, accelerator …

Abstract:

This work presents a power-efficient level crossing (LC) ADC designed to digitize sparse signals. It uses dynamically self-biased comparators, which require minimal current when the input voltage is far from a decision threshold. It also uses a DAC architecture which avoids the signal attenuation commonly present in prior LC ADC …
