Device capable of conducting business hardware acceleration and method thereof

Abstract

The invention provides a device capable of conducting business hardware acceleration. The device comprises a logic hardware acceleration module and a central processing unit (CPU). The logic hardware acceleration module is configured to receive down data message from a core network and stores the down data message into an internal memory of the CPU. The CPU is configured to obtain the down data message from the internal memory and conduct CPRS tunnel protocol user face portion (GTPU) protocol processing and message data converge protocol (PDCP) on the down data message. The logic hardware acceleration module is further configured to execute radio link control (RLC) processing on the data message subjected to the PDCP processing to generate an RLC protocol data unit (PDU), execute frame protocol (FP) framing processing on the RLCPDU and packaging processing to generate Ethernet message and transmit the down Ethernet message. By means of the business hardware acceleration scheme, the device can greatly reduce CPU load, reduces user face message processing delay and improves processing performance and processing capacity of the whole business.

Description

technical field [0001] The present invention generally relates to a mobile communication system, and specifically relates to a device and method capable of hardware acceleration of high-speed uplink services and high-speed downlink services in the mobile communication system. Background technique [0002] With the development of mobile broadband services, the global information and communication market is facing a significant change. It is foreseeable that in the next few years, mobile bandwidth will generate huge growth. The huge increase in wireless traffic has brought great challenges to the performance of service processing single boards (for example, WCDMA service processing single boards), which requires several times or even ten times of specification improvement in processing capacity. General-purpose processors gradually gain an advantage in the fusion process of information technology and communication technology, but the speed of general-purpose processors in the...

Problems solved by technology

Although the programmability of the NP acceleration unit has a certain degree of flexibility, the NP acceleration unit is only mainly oriented to forwarding and processing network packets, and its efficiency in processing complex services is low, so it can only perform some simple and repetitive processing

It can be seen that the functions of this type of NP processing unit are mostly limited, its flexibility is not enough, the processing capacity is not enough, and the business processing capacity of the entire chip is not enough
