Abstract

Abstract

With the growing abundance of data-intensive applications, memory wall has become a bottleneck to computing efficiency. A novel Floating Point (FP) computing infrastructure that embeds Ferroelectric Field Effect Transistor (FeFET) based Ternary Content Addressable Memories (TCAMs) for energy efficient computing is proposed. With an ultra-dense TCAM implementation following the designed guidelines, the infrastructure can replace unnecessary Float Point Unit (FPU) executions with more efficient TCAM searching, thereby saving the overall energy consumption. Thanks to the proposed execution flow, the infrastructure can achieve up to 33% energy saving compared to regular FPUs.
