摘　　要：可编程晶振以其输出频率可编程的特性,非常适合应用在码速率可变的弹、箭或卫星测控通信系统中,但使用传统的基于RTL编程方式对可编程晶振进行配置存在抽象层级低、代码实现复杂、开发效率低、调试难度大等缺点;针对上述问题提出了一种基于高层次综合技术的可编程晶振自适应配置方案;利用高层次综合技术实现了晶振参数的浮点计算及IIC总线通信,并以此为基础实现了可编程晶振的自适应配置;经测试,相对于传统RTL实现方式,使用高层次综合技术实现可编程晶振的参数计算和配置,其代码量仅为前者的1/10至1/20,开发周期仅为前者的1/4至1/10,且代码运行效率并无明显降低;结果表明,高层次综合技术不仅能够有效提高FPGA在算法开发、数据处理等领域的设计、开发效率,在FPGA接口和时序设计方面也有较好的应用和推广价值。Programmable crystal has the characterics of its output frequency programmable,it is ideal for use in bullet,arrow or satellite measurement and control communication systems with variable code rates,but programming methods based on traditional register transfer level(RTL)are used to configure the programmable crystal,it has disadvantages such as low abstraction level,complex code implementation,low development efficiency and difficulty in debugging.A programmable crystal adaptive configuration scheme based on high level synthesis technology is proposed to address above problems;the floating point calculation of crystal pa-rameters and Inter-Integrated Circuit(IIC)bus communication are realized using the high level synthesis technology,on this basis,the adaptive configuration of programmable crystal is realized.After the experimental testing,the high level synthesis technology is used to achieve the parameter calculation and configuration of programmable crystal oscillators,the code quantity of the high level synthesis technique is only 1/10 to 1/20 that of traditional RTL implementations,and the development cycle is only 1/4 to 1/10 of the former,with no significant reduction in code running efficiency.The results show that the high-level synthesis technology can not on-ly effectively improve the design and development efficiency of FPGA in the fields of algorithm development and data processing,but also has a good application and promotion value in FPGA interface and timing design.
