摘要
针对国内研制出的多类仪器仪表中基带板的设计仅限于通过实现来验证其可行性的问题,提出在基带板设计之前对可行性进行分析,防止在实现时芯片资源不足而导致人力和时间等资源的浪费,同时为增强型长期演进空口监测仪中基带板的设计提供参考。根据增强型长期演进特性以及监测仪需求确定核心处理器的选型;重点对基带板上存储器的存储能力和总线能力进行分析,确保所选的元器件有足够的能力并留有一定的余量;最终通过在基带板上的测试证明该可行性分析的正确性,也为其他的硬件芯片选型提供参考。
The design of the baseband board for many types of instrumentations developed in China was limited to verify its feasibility by implementation.The feasibility analysis before the design of the baseband board is proposed to prevent the waste of the manpower and time resources because of the shortage of chip resources,which provides a reference for the design of the baseband board in the field-programmable gate array air interface analyzer.Firstly,the core processor based on LTE-A(Long Term Evolution-Advanced)characteristics and monitor requirements is determined.Then the storage capacity and bus capacity of the baseband board are focused on to ensure that the selected components have sufficient capacity and margin.The correctness of feasibility analysis is proved through the test on the baseband board,and provides reference for other hardware chip selection.
