The broader impact of this Small Business Innovation Research (SBIR) Phase I project is to improve the performance of semiconductor chips. Specifically, it develops a novel method to operate directly on compressed data, saving time, energy, and latency. This improved performance will affect computationally intensive applications such as medical imaging (e.g., CT/MRI), climate simulation, hurricane warnings, and earthquake alerts.This Small Business Innovation Research (SBIR) Phase I project develops a method to operate on compressed data. Today, computers apply data compression to identify and remove redundancy in the data in order to save storage space. Computers apply arithmetic to compute in integers or real numbers (usually represented internally as floating-point data). However, today's computers first decompress the data, compute, and then compress the computed result, consuming additional time and energy. This project develops an arithmetic and math hardware accelerator capable of processing compressed data directly to dramatically improve computation performance, storage effectiveness, and energy efficiency. This project combines data compression and floating-point engineering to deliver the first-ever Compressed Floating-Point Unit (CFPU) that minimizes semiconductor and energy usage and reduces computation latency.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I阶段项目的更广泛影响是提高半导体芯片的性能。 具体而言，它开发了一种直接在压缩数据，节省时间，能量和延迟的新方法。 这种改进的性能将影响计算密集型应用，例如医学成像（例如CT/MRI），气候模拟，飓风警告和地震警报。这项小型企业创新研究（SBIR）I阶段项目开发了一种在压缩数据上操作的方法。如今，计算机应用数据压缩以识别和删除数据中的冗余，以节省存储空间。 计算机将算术应用于整数或实数（通常在内部表示为浮点数据）中。 但是，今天的计算机首先对数据进行解压缩，计算并压缩计算结果，从而消耗额外的时间和能量。 该项目开发了一个算术和数学硬件加速器，能够直接处理压缩数据，以显着提高计算性能，存储效率和能源效率。 该项目结合了数据压缩和浮点工程，以提供有史以来的第一个压缩浮点单元（CFPU），该单元（CFPU）最小化半导体和能源的使用情况，并减少计算延迟。该奖项反映了NSF的法定任务，并被认为是通过该基金会的知识分子优点和广泛影响的评估来评估的，并被视为值得的支持。
