1.An 8-bit microcomputer with 16-bit bus requires PROM space of 4Kx8 and RAM space of 4Kx8. The only available devices are PROM of 2Kx8 and RAMs of 1Kx8. i). Draw the memory map for the above system given that the PROMs occupy the lower address space starting from 0000H. ii). Show the pin configuration for the RAM and PROM chips. iii). Determine the number of chips required. iv). Draw the memory chip interconnections for the memory map in (i) above
