Problems solved by technology

It can be seen that the upgrade of the FPGA version also needs to consume memory costs, and its process includes not only ordinary loading operations, but also operations such as communication with the motherboard card, file programming, and space address exchange, which means that the process of upgrading the FPGA version is more cumbersome. As a result, the boot time of the daughter board is longer

Embodiment Construction

[0115] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0116] Under the framework of the existing base station system, both the main board and the sub-board have completed the backplane design, so the wiring resources of the main board or the sub-board are very limited. However, in the process of passive loading of FPGA, the main board needs to transmit more than one configuration command and more than one configuration data to the sub-board through the data cable of the backplane, that is, both the main board and the sub-board need to use multiple backplanes It is impossible for the main board and daughter board of which the backplane design has been completed, so the passive loading of the FPGA is basically impossible to realize, which discourages those ski...

Abstract

The application provides a board communication method, a board and a method and a system for loading an FPGA (Field-Programmable Gate Array). The sending terminal board communication method specifically comprises the steps that a sending terminal board encapsulates transmission data as a data frame; the sending terminal board carries out clock combining on the data frame to obtain corresponding combined data; and the sending terminal board sends the combined data to a receiving terminal board through a data line of a backplane. Under the premise of saving the wiring source of the backplane, the loading of the FPGA is finished with less storage cost, and the startup time of the board where the FPGA is positioned is shortened.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a board communication method, a board, and an FPGA loading method and system. Background technique [0002] Currently FPGA (Field Programmable Gate Array, FieldProgrammableGateArray) has programming flexibility and high-speed hardware, so it is more and more widely used. [0003] In the current TD-SCDMA (Time Division Synchronous Code Division Multiple Access, TimeDivision-SynchronousCodeDivisionMultipleAccess) base station system, FPGA devices are widely used. For example, a base station system is composed of a mainboard card and a subboard, wherein the mainboard card may specifically include: MCU (Micro Control Unit, MicroControlUnit), Flash (flash memory), and EPLD (Erasable Programmable Logic Device, Erasable ProgrammableLogicDevice) , interface connectors and other devices, the daughter board can specifically include FPGA devices, Flash, EPLD, interface conn...
