Each instance is under the scope of a DMA Remapping hardware unit. From a software perspective, each instance is exposed as a PCI-Express Root Complex Integrated Endpoint. A multi-socket server platform may support multiple such SoCs.
Memory Compare and delta generate/merge to support VM migration, VM Fast check-pointing and software managed memory deduplication usages.Įach SoC may support any number of Intel® DSA device instances. Generate and test CRC checksum, or Data Integrity Field (DIF) to support storage and networking applications. Enumeration and configuration is done with a PCI Express* compatible programming interface to the Operating System (OS) and can be controlled through a device driver.īesides the basic data mover operations, Intel® DSA supports a set of transformation operations on memory. Intel® DSA enables high performance data mover capability to/from volatile memory, persistent memory, memory-mapped I/O, and through a Non-Transparent Bridge (NTB) device to/from remote volatile and persistent memory on another node in a cluster. The goal is to provide higher overall system performance for data mover and transformation operations, while freeing up CPU cycles for higher level functions. Intel® DSA replaces the Intel® QuickData Technology, which is a part of Intel® I/O Acceleration Technology. Intel® DSA is a high-performance data copy and transformation accelerator that will be integrated in future Intel® processors, targeted for optimizing streaming data movement and transformation operations common with applications for high-performance storage, networking, persistent memory, and various data processing applications.

Here's the place to find additional information about that Project. This is another way to interact with the developers of a Project, solve your questions or contribute to improve it: IRC channels. Click here to find and download 01.org Projects' files! See allīug tracking allows the developers to have a record of the bugs and issues found in an application for a more efficient way to fix them.
Github repositories are the most preferred way to store and share a Project's source files for its easy way to navigate repos.
A more direct channel to solve your questions and help others to get involved. See allĪ mailing list improves communication for all the people interested in a 01.org Project: developers, final users and contributors. This establishes a clear link between 01 and the project, and help to have a stronger presence in all Internet. To provide more information about a Project, an external dedicated Website is created.
