Problems solved by technology

[0005] The following problems exist in the existing technology: Most of the existing development platforms are partially verifying the protocol, such as using the PHY module of the existing wireless network card to verify the MAC layer protocol, or the designed FPGA development platform can only verify the hardware in the protocol alone The logic part is not suitable for verifying the software-hardware combination development protocol, or the designed software-hardware collaborative platform can meet the requirements of verifying the software-hardware collaborative design, but the corresponding FPGA resources are too few

Abstract

The invention relates to a wireless communication technology, in particular to a hardware platform device for verifying system-on-chips. The hardware platform device comprises a media access control upper unit, a media access control lower unit, a digital baseband verification unit and a management expansion interface unit, wherein the media access control upper unit is connected with a host machine, and is connected with the media access control lower unit through a high-speed mezzanine card (HSMC) connector; the media access control lower unit is connected with the media access control upper unit through the HSMC connector; the digital baseband verification unit is connected with the media access control lower unit, and provides an upstream interface and a downstream interface; and the management expansion interface unit is connected with the media access control upper unit. By the hardware platform device, functions of a media access control layer, a physical layer, an analog to digital(AD) / digital to analog (DA) front end and the like are conveniently realized; the shortcomings caused by independently debugging software or hardware are overcome; and software and hardware collaborative simulation verification is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a hardware platform device for verifying a system-level chip. Background technique [0002] With the development of multimedia applications such as high-definition television, online video, and online games, the user's demand for the data transmission rate of wireless local area network (WLAN, Wireless Local Area Network) is increasing rapidly. The physical layer rate specified in the 802.11n standard is 600Mbps, which is high The transmission rate puts forward higher requirements on the overall system platform. [0003] The physical layer protocols of the new generation of mobile communications, wireless local area network, wireless metropolitan area network, and high-speed short-distance wireless communication systems for advanced international mobile communications (IMT-Advanced) have many common features: (1) The occupied signal bandwidth is 20MHz Or 40MHz, t...
