In recent years,as China has finished the updating of the fourth generation of network,for guaranteeing the information security of the state,communication chip with complete independent intellectual property right must be possessed to support the advancement of such project.TD-LTE Baseband Chip is a super-large-scale integrated circuit designed basing on SOC,which needs to carry out coding,etc to the transmitted baseband signal,or carry out decoding,etc to the received baseband signal.LPDDR2 SDRAM is used in the chip design process due to its low power dissipation,high capacity and high reliability.As PHY in the controller architecture of LPDDR2 SDRAM adopts hard core design,it cannot be achieved in Virtex-7 2000T prototype verification platform.This design mainly builds on such prototype verification platform to propose the verification scheme of LPDDR2 SDRAM controller in TD_LTE baseband chip,so as to guarantee that prototype verification in FPGA can be carried out by TD_LTE baseband system,and meanwhile high capacity storage space can be provided to the system.
In recent years, as China has finished the updating of the fourth generation of network, for guaranteeing the information security of the state, communication chip with complete independent intellectual property right must be possessed to support the advancement of such project. TD-LTE Baseband Chip is a super-large-scale integrated circuit designed basing on SOC, which needs to carry out coding, etc to the transmitted baseband signal, or carry out decoding, etc to the received baseband signal. LPDDR2 SDRAM is used in the chip design process due to its low power dissipation, high capacity and high reliability. As PHY in the controller architecture of LPDDR2 SDRAM adopts hard core design, it can not be achieved in Virtex-7 2000T prototype verification platform. This design mainly builds on such prototype verification platform to propose the verification scheme of LPDDR2 SDRAM controller in TD_LTE baseband chip, so as to guarantee that prototype verification in FPGA can be carried out by TD_LTE baseban d system, and meanwhile high capacity storage space can be provided to the system.
