运用VHDL硬件语言完成了激光成像雷达中扫描系统控制的描述。设计由ALTERA公司的MAX7000系列可编程逻辑器件实现。VHDL语言与可编程逻辑器件(CPLD)的结合使用,将传统上由硬件电路实现的功能转变为软件参与实现,从而易于修改和改进。给出了部分VHDL源代码描述,通过逻辑综合优化了设计,实现了设计的时序仿真,分析了VHDL语言在设计中应注意的一些问题。 The VHDL hardware language is used to describe the control of scanning system in laser imaging radar. The design is implemented by ALTERA’s MAX7000 family of programmable logic devices. The combination of the VHDL language and the programmable logic device (CPLD) translates the functions traditionally performed by hardware circuits into software-enabled implementations for easy modification and improvement. Some VHDL source code descriptions are given, and the design is optimized through logic synthesis to achieve the timing simulation of the design, and some problems that should be noticed in VHDL language design are analyzed.
