Title: The Innovations of Aaron Jay Goldberg

Introduction

Aaron Jay Goldberg is a notable inventor based in Princeton, NJ (US). He has made significant contributions to the field of memory system performance through his innovative patent. His work is particularly relevant in an era where processor speeds are rapidly increasing, often outpacing improvements in memory systems.

Latest Patents

Goldberg holds a patent titled "Interrupt-based hardware support for profiling memory system performance." This invention addresses the growing gap between processor speed and memory system performance. It combines simple hardware support with sampling techniques to gather empirical data on memory behavior. This data is crucial for architects, compiler writers, and application programmers as they seek to optimize memory usage. The patent describes a method of augmenting a cache miss counter with a compare register and interrupt line, allowing the processor to be interrupted when the counter matches the compare value. This enables the sampling of system state and the development of cache miss profiles associated with specific processes and system states. The idea is implemented in the Mprof prototype, which profiles data stall cycles and cache misses on the Sun Sparc 10/41.
