STD_LOGIC_UNSIGNED和STD_LOGIC_SIGNED程序包的区...LOGIC_UNSIGNED则正好相反。
举一反三
- STD_LOGIC_UNSIGNED和STD_LOGIC_SIGNED程序包的区别是，STD_LOGIC_SIGNED中定义的运算符考虑到了符号，是有符号数的运算，而STD_LOGIC_UNSIGNED则正好相反。
- 程序包()在STD_LOGIC_1164程序包的基础上扩展了三个数据类型:UNSIGNED、SIGNED和SMALL_INT,并为其定义了相关的算术运算符和转换函数。 A: STD_LOGIC_SIGNED B: STD_LOGIC_ARITH C: STD_LOGIC_UNSIGNED D: STD_LOGIC_1164
- Based on the attributes of logic, logic can be divided into five types， and which of the following is not the right type?（ ） A: Aristotelian logic B: modern inductive logic C: traditional logic, D: mathematical logic
- PLC英文名称？ A: Programmable Logic Controller B: Personal Logic Controller C: Programmable Logic Computer D: Personal Logic Computer
- In English logic is implicite. So logic indicators are not needed.
