ZX-Spectrum-Component-Video

The ZX Spectrum in its original form produces a radio frequency signal that can be fed into an analog TV. The quality of this signal is very poor, but this can be improved by a simple modification that will make the ZX Spectrum output a composite video signal instead.

Basic Binary Division: The Algorithm and the VHDL Code

Based on this algorithm, we’ll derive a block diagram for the circuit implementation of binary division. Finally, we’ll look at the ASMD (Algorithmic State Machine with a Data path) chart and the VHDL code of this binary divider. Consider dividing 11000101 by 1010.
