Design an 4K X 8 EPROM ( with two enable lines, CE and OE ) based system to display the squares of BCD digits on seven segment displays using a minimum number of 74LS47 BCD to seven segment converters. Each BCD digit will be input to the EPROM via switches. The square of a particular BCD number will be displayed in BCD each time the 4-bit number is input to the EPROM via the switches. Draw a block diagram of your implementation showing the contents of memory along with addresses in hex.
