These arithmetic logic units (ALU)/function generators perform 16 binary arithmetic operations on two 4-bit words. These operations are selected by the four function-select lines (S0, S1, S2, and S3) and include addition, subtraction, decrement and straight transfer. When performing arithmetic manipulations, applying a low-level voltage to the mode control input (M) must enable the internal carries. A full carry look-ahead scheme is available in these devices for fast, simultaneous carry generation by means of two cascade-outputs (P and G) for the four bits in the package. Using this demonstrator it is possible to perform and verify the following functions - Two arithmetic operations: Addition and Subtraction of 4-bit binary words.
- Five logic operations: AND, NAND, OR, NOR, AND exclusive - OR.
In order to accomplish the above tasks, required address selector switches, DATA selector switches, push switches, LED indicators for ADDRESS and DATA are provided in the equipment itself. This trainer comes with necessary power supplies.
