Using the memory map design an absolute decoding circuit, Computer Engineering

Assignment Help:

Using the memory map below; design an absolute decoding circuit.

  The technique is to spot the differences between the start and stop of each device. The Ram chip has the following addresses, which are the same

  A15 -> A8 = 0000 0000

Therefore we require an 8 bit OR gate connected to A15 -> A8 and that should select the circuit. (Remember chip select is active low). For the EPROM the following addresses are the same: -

  A15 -> A8 = 1111 1111

Therefore we require an 8-bit NAND gate to select the EPROM.
