A young engineering student is in the process of designing a new embedded system whose size is similar to a regular ATM machine, using the only available 13-bit address microprocessor in a university lab. Her analysis shows that the system will require a minimum of 4Kbytes of RAM to run smoothly. a. Which type of digital circuit does she need to design to create an interface between her processor and memory? b. The table below shows a list of active low chips available to her. The chips are only sold in packages and the table shows their prices. Using the information in the table, what would be the cheapest but most efficient design of the circuit in (a) above, if i. The design will be mass produced ii. Only a single instance of the design will be needed. (Assume most efficient circuit is the one with the least number of gates) = Type of Chip IKB RAM Cost per package 29 Chips per package 4 2KB RAM 30 2 4KB 34 2 512B RAM Freely provided by the university lab (but only 3 available) 1 2 Simple gates (NAND, NOR, NOT, AND, etc) A young engineering student is in the process of designing a new embedded system whose size is similar to a regular ATM machine, using the only available 13-bit address microprocessor in a university lab.
