1. Functional Block Diagram Components
The functional block diagram is only composed of rectangular components.
Rectangular components are divided into non enabled rectangular components and enabled rectangular components.
1.1. Without enabling rectangular components
图1 Without enabling rectangular components
This type of component does not enable input, all inputs are operands.
Perform operations on the operands and output the results to the right.
The AND and OR components can be connected to sub logic on the left side.

1.2. Enabling rectangular components
图3 Enabling rectangular components
Enable input determines whether the instruction is executed, and enable output determines whether the next instruction is executed.
The Boolean values of enable input and enable output are equal.
