Building a computer from individual components without chips isn’t something new ... The ALU is a 4-bit ripple-carry adder/subtractor, with plans for a comparison unit that will be responsible ...

Computers built using discrete logic chips? Seen it. Computers from individual ... Everything is modular, so four of his 4-bit adder cards eventually get together to form a 16-bit adder, which ...

Figure 4: Voltage-switchable 2-bit adder and a 4-bit digital-to-analog ... a combination of optical and electrical inputs. The on-chip architectures are scalable and completely compatible with ...

This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx. Catch up on the latest ...
