A childhood construction toy has been transformed into a working 8-bit mechanical computer that can perform real math.

Arithmetic logic unit (ALU) is an important part of microprocessor. In digital processor logical and arithmetic operation executes using ALU. In this paper we describes 8-bit ALU using low power ...

This 8-bit ALU is designed using single electron transistor using SPICE software and compared with conventional CMOS. Based on the results obtained, it is proved that the single electron 8-bit ALU ...
