Data real-time processing and storage device

Abstract

The embodiment of the invention discloses a stream processor which is used for shortening stream processing cycle and improving capability of processing highly real-time services. According to the method, a first in first out (FIFO) memory, an arithmetic unit and a high-speed cache are included. The FIFO memory receives current stream information, wherein the current stream information carries a target stream number and target data; when the FIFO memory receives read valid signals, the FIFO memory sends the target stream number and the target data to the arithmetic unit and sends the target stream number to the cache. The cache obtains old data corresponding to the target stream number according to the target stream number and sends the old data corresponding to the target stream number to the arithmetic unit. The arithmetic unit performs calculation on the old data corresponding to the target stream number to obtain new data, and sends the new data to the cache.

Description

technical field [0001] The present application relates to the field of data processing and data storage, in particular to a real-time data processing and storage device. Background technique [0002] In recent years, with the rapid development of new services such as big data, virtual reality (virtual reality, VR), augmented reality (augmented reality, AR), unmanned driving, mobile Internet and Internet of things (internet of things, IOT), 100 / 400GE (Gigabit Ethernet, Gigabit Ethernet) and other network interconnection protocol (internetprotocol, IP) interfaces are developing towards ultra-high-bandwidth (UHB) Ethernet interfaces represented by 100400GE. In UHB technology In the process of rapid evolution, the strong real-time requirements for stream processors to process massive data streams are constantly increasing. At the same time, in such a high-speed process, the requirements for timely and reliable data storage are also high. [0003] In the existing data flow proc...
