ARINC 818 (Avionics Digital Video Bus) is a point-to-point, 8b/10b-encoded (or 64B/66B for higher speeds) serial protocol for transmission of video, audio, and data. The protocol is packetized but is video-centric and very flexible, supporting an array of complex video functions including the multiplexing of multiple video streams on a single link or the transmission of a single stream over a ...
OpenCAPI Memory Interface (OMI) is a serial attached RAM technology based on OpenCAPI, providing low latency, high bandwidth connection for main memory. OMI uses a controller chip on the memory modules that allows for technology agnostic approach to what is used on the modules, be it DDR4, DDR5, HBM or storage class non-volatile RAM. An OMI ...
UPI is a low-latency coherent interconnect for scalable multiprocessor systems with a shared address space.It uses a directory-based home snoop coherency protocol with a transfer speed of up to 10.4 GT/s.
The interconnect network for a shared memory multiprocessor system must have low latency and high bandwidth unlike other network systems, like local area networks (LANs) or internet [citation needed] for three reasons: Messages are relatively short as most messages are coherence protocol requests and responses without data.
The current specification HTX 3.1 remained competitive for 2014 high-speed (2666 and 3200 MT/s or about 10.4 GB/s and 12.8 GB/s) DDR4 RAM and slower (around 1 GB/s similar to high end PCIe SSDs ULLtraDIMM flash RAM) technology [clarification needed] —a wider range of RAM speeds on a common CPU bus than any Intel front-side bus. Intel ...
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers.
The earliest academic publication of trace cache was "Trace Cache: a Low Latency Approach to High Bandwidth Instruction Fetching". [1] This widely acknowledged paper was presented by Eric Rotenberg, Steve Bennett, and Jim Smith at 1996 International Symposium on Microarchitecture (MICRO) conference.
Data center and HPC analytics systems have been deployed using a RapidIO 2D Torus Mesh Fabric, [11] that provides a high speed general purpose interface among the system cartridges. This allows for applications that benefit from high bandwidth to low latency node-to-node communication.
