Abstract
Central processing units (CPUs) in computing systems manage graphics processing units (GPUs), network processors, security co-processors, and other data heavy devices as buffered peripherals using device drivers. Unfortunately, as a result of large and latency-sensitive data transfers between CPUs and these external devices, and memory partitioned into kernel-access and user-access spaces, these schemes to manage peripherals may introduce latency and memory use inefficiencies. Proposed are schemes to reduce latency and redundant memory copies using virtual to physical page remapping while maintaining user/kernel level access abstractions.
