Architecture and Performance of the Direct RDRAM

About the talk:

Over the past decade, rising clock speeds and advances in processor design such as superscalar processing and simultaneous multithreading have led to dramatic increases in CPU performance. Over the same time period memory performance has increased more slowly, with increases coming more from advances in manufacturing rather than from revolutionary architectural improvements. Consequently, the processor-memory performance gap has grown wider. If these trends continue, the performance of future computing platforms will be constrained more and more by the performance of their memory systems.

This talk will describe the Direct Rambus DRAM (Direct RDRAM), a novel architecture designed to help reduce the processor-memory performance gap. The Direct RDRAM was designed to meet the needs of several computing environments, including home entertainment units, desktop personal computers, laptops, and workstations/servers. Some of the important design considerations for these computing environments will be discussed, along with how they ultimately manifested themselves in the Direct RDRAM architecture. A discussion of the performance advantages of systems that utilize Direct RDRAMs compared to systems that use other commercially-available alternatives will be included.

About the speaker:

Steven Woo is a Member of the Technical Staff in the Logical Architecture Group of Rambus Inc., a company that designs, develops, and licenses its high-speed chip-to-chip interface technology to enhance the performance and cost-effectiveness of computing systems.
