基本逻辑门是一些简单的布尔函数的实现,我们需要的基本逻辑门如下,有1位和多位(16位)之分。 我们所有组合逻辑芯片都是基于Nand实现的,下面是Nand的真值表:只有当两个输入都为1时输出为0,其余输出为1反,然后输出。 首先我们用Nand实现一个Not。Not很简单,对其输入取反,然后输出。下面是我自己的实现方式: HDL实...
请用verilog,iplement a 32-bit ALU with the following function.ALU operation logic function00 A OR B01 A XOR B10 (A AND (B XNOR C))11 ((A XOR B) NAND C)the logic function should only be implement structurally using 2-input NAND,2-input NOR & INVERTER GATES.the multiplexer should ...
This will turn on the large PMOS switching transistor 2420B, IF the other input to NAND gate 2434 is also high. However, note that BAT is also connected directly to the input of inverter 2430. If BAT is not high enough to drive the output of 2430 low, then the output of inverter ...
(which are capable of performing various logical functions, such as a single logical operation, for example, an AND function, an OR function, a NOT function, a NAND function, a NOR function, or an XOR function, as well as combinations of logical functions) provided in a netlist. A ...
