Abstract
Official abstract text for this publication.
A method for facilitating direct memory access in a computing system in response to a request to transfer data is provided. The method comprises selecting a thread for transferring the data, wherein the thread executes on a processing core within the computing system; providing the thread with the request, wherein the request comprises information for carrying out a data transfer; and transferring the data according to the request. The method may further comprise: coordinating the request with a memory management unit, such that virtual addresses may be used to transfer data; invalidating a cache line associated with the source address or flushing a cache line associated with the destination address, if requested. Multiple threads can be selected to transfer data based on their proximity to the destination address.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for facilitating direct memory access, the method comprising: an application submitting a request to a data movement software to transfer data from a virtual source memory address to a virtual destination memory address, wherein the application is executed on a first core among a plurality of cores in a multi-core processor chip, wherein the first core is associated with a first on-chip cache exclusively dedicated to the first core, wherein at l…
