Abstract

Computer systems use the virtual memory system to manage memory and allow the operating system to manage memory for the user process. This virtual memory has a tax of requiring an address translation for every Load or Store instruction (which is about 20% of all program instructions). Lately, this address translation has become a bottleneck for performance. In this proposal, we would like to explore the benefits of re-organizing the page table (using different data structures, etc.).
