The Price of Safety: Evaluating IOMMU Performance
IOMMUs, IO Memory Management Units, are hardware devices that translate device DMA addresses to machine addresses. An isolation capable IOMMU restricts a device so that it can only access parts...
Understanding the Effects of Wrong-Path Memory References on Processor Performance
High-performance out-of-order processors spend a significant portion of their execution time on the incorrect program path even though they employ aggressive branch pre-diction algorithms. Although memory references generated on the...
Cache Filtering Techniques to Reduce the Negative Impact of Useless Speculative Memory References on Processor Performance
High-performance processors employ aggressive speculation and prefetching techniques to increase performance. Speculative memory references caused by these techniques sometimes bring data into the caches that are not needed by correct...
Efficient Runahead Execution: Power-Efficient Memory Latency Tolerance
Runahead execution improves memory latency tolerance without significantly increasing processor complexity. Unfortunately, a runahead execution processor executes significantly more instructions than a conventional processor, sometimes without providing any performance benefit,...
DMA Support in KMDF Drivers
The paper describes how Microsoft Windows drivers support Direct Memory Access (DMA) devices, using the Windows Driver Foundation (WDF) kernel-mode driver framework. Because understanding Windows DMA architecture is the key...
