employs RAM chips of 256 x 8 and Q) A microprocessor ROM chips of 1024 x 8. The microcomputer system needs 2K bytes of RAM and 4K bytes of ROM. The three bits of the address bus are assigned as 10, 11 & 12 for RAM and ROM. Assume that microprocessor has 16-bit address bus and 8-bit data bus. a) How many RAM and ROM chips are needed? b) Draw a memory-address map for the system. c) Draw the schematic (block) diagram, which shows connection of RAM, ROM and decoders connected with the microprocessor. Please also show the Rd. & Wr. (Read and Write pins connection between microprocessor and memories). d) Define the term random access with respect to RAM. e) What will happen if the memory is organized as high and low banks? Please compare the two schemes for selecting the banks, with respect to merits, demerits and limitations. The report must contain the following information, 1. Introduction 2. Methodology of your technique 3. Working principle 4. Block diagram (if required) 5. Calculations 6. Results 7. Reference
