Consider the following system design problem.There are two peripherals, each of 64 bytes, and two memory chips, each of 64 bytes, which are to be interfaced to a processor. The designer wants that the addresses allocated to the memory chips and to the peripherals are independent of each other. Furthermore, while designing the control unit, he wants the RISC implementation with fast operation. Identify the configuration of the system that he shall choose.What should be the minimum address bus bits needed for implementing this configuration of memory and IO chips?Now assume that Heraj said to him Anna, you cannot easily modify the control unit which you have designed, why not you explore the ..... control unit design option? What is the appropriate term which should come in this blank?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Consider the following system design problem.There are two peripherals, each of 64 bytes, and two memory chips, each of 64 bytes, which are to be interfaced to a processor. The designer wants that the addresses allocated to the memory chips and to the peripherals are independent of each other. Furthermore, while designing the control unit, he wants the RISC implementation with fast operation. Identify the configuration of the system that he shall choose.What should be the minimum address bus bits needed for implementing this configuration of memory and IO chips?Now assume that Heraj said to him “Anna, you cannot easily modify the control unit which you have designed, why not you explore the ____ control unit design option?” What is the appropriate term which should come in this “blank"?

A	isolated IO mapping and microprogrammed control unit; 8 bits;hardwired control unit
B	isolated IO mapping and hardwired control unit; 8 bits; microprogrammed control unit
C	memory mapped IO mapping and hardwired control unit; 6 bitsmicroprogrammed control unit
D	IO mapped IO mapping and hardwired control unit; 128 bits;microprogramed control unit
E	isolated IO mapping and hardwired control unit; 8 bits; hardwired control unit

Explanation:

Detailed explanation-1: -The clock is used for handshake control between different parts of the system.It permits the synchronization for the CPU to get the right data. It permits the synchronization between peripherals and main memory to transfer data properly.

Detailed explanation-2: -i) CPU ii) Primary memory iii) Input device and iv) Output device. They are referred to as hardware of computer. Computer system has two types of primary memories viz. i) RAM the volatile memory and ii) ROM the non-volatile memory.

Detailed explanation-3: -External devices are not connected directly to the system bus because they have a wide range of control logics, as well as data transfer speeds and formats.

Detailed explanation-4: -The most common peripherals are a printer, scanner, keyboard, mouse, tape device, microphone, and external modem that are externally connected to the computer.
