Using a timer, design a display system that reads the ASCII characters from a 64-word 8-bit register file RF and w1ites each word to a 2-row LED-based display having 32 characters per row, doing so 100 times per second. The display has an 8-bit input A for the ASCII character to be displayed, a single-bit input row where 0 or 1 denotes the top or bottom row respectively, a 5-bit input col that indicates a column in tJ1e row, and an enable input en whose change from 0 to 1 causes the character to be displayed in tJ1e given row and colmnn. The system should write RF{O] through RF[ LS] to row O's columns 0 to 15 respectively, and Rfll6] to RF{3 1] to row J.
