AMC (advanced mezzanine card) board card structure based on MicroTCA (telecom and computing architecture) standard and connection type thereof

Abstract

The invention relates to an AMC (advanced mezzanine card) board card structure based on a MicroTCA (telecom and computing architecture) standard and a connection type thereof. The AMC board card structure comprises AMC board cards and an MCH (metal ceramics heater) board card which are arranged on a MicroTCA standard system back plate, and is characterized in that each AMC board card is also provided with an SRIO (serial rapid input / output) switch chip, an MMC (multi media card) chip and DSP (digital signal processing) chips, wherein the SRIO switch chip comprises data processing channels and an AMC board card interconnection channel, the number of the data processing channels is the same as that of the DSP chips, the data processing channels are connected with the DSP chips, and the AMC board card interconnection channel is connected to the back plate through an AMC connector; the MMC chip adopts an ARM (advanced RISC machines) microcontroller chip, and the ARM microcontroller chip is connected with an MCH board card through an IPMI (intelligent platform management interface); and the DSP chip is connected to the ARM microcontroller chip through a UART (universal asynchronous receiver / transmitter). Each AMC board card respectively establishes interconnection topologies with the AMC board cards, same in quantity, positioned on the two sides of each AMC board card through the SRIO switch chip, so that software and hardware pressures concentrated on the MCH can be directly scattered to each AMC board card, further the resource space of the MCH can be saved and the resource allocation of the system can be balanced; meanwhile, the AMC board cards can be flexibly configured, the bandwidth can be increased and decreased timely, and the stability and reliability of the system and the flexibility of the configuration can be enhanced, thus the AMC board card is applied to the design requirements of telecommunication equipment in a high-definition era.

Description

technical field [0001] The invention relates to a telecommunication-level data processing device, in particular to an AMC board structure and connection method based on the MicroTCA standard. Background technique [0002] MicroTCA is a medium and low-cost equipment specification defined by the international organization PICMG on the basis of ATCA (Advanced Telecom and Computing Architecture) defined by PICMG 3.0. It is one of the most important industrial standards for the new generation of telecommunications and computer equipment. [0003] As a supplement to the AdvanedTCA standard, a popular modular hardware platform standard in the industry today, the MicroTCA hardware technology standard is mainly aimed at applications such as network communication, medical image processing, embedded control and military industry. Its high bandwidth, modularity and flexibility And the advantages of high cost performance have been applied to a wider range of application fields, and becom...

Problems solved by technology

This not only occupies the limited space resources of the MCH, but also increases the difficulty of design and the power consumption of the board. Once the design is completed, the number of SRIO channels interconnected with the AMC board is fixed, which cannot be flexibly configured, and the hardware upgrade cycle is too long. the cost is too high

These factors are not conducive to the promotion and use of products
