Model Exam – I

PART – A                              10x 2=20

1.        What is mainframe computer?                                                 (CO1)

Mainframe computers (colloquially referred to as "big iron") arecomputers used primarily by large organizations for critical applications, bulk data processing, such as census, industry and consumer statistics, enterprise resource planning, and transaction processing.

2.        Define microcomputer.                                                                            (CO1)

A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board.

3.        What is overflow and underflow case in single precision?                      (CO2)

A processing system that determines whether an underflow or overflow condition has occurred concurrently with the determination of the floating point exponent result uses a group of latched constants which can be added to the intermediate exponent and the exponent adjust to determine out of range conditions for all cases.

4.     Discuss the IEEE format used for representing single- precision floating point numbers.                                                                                              (CO2)

Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base-2 format is officially referred to as binary32. It was called single in IEEE 754-1985.

5.        What is pipeline register delay?                                                               (CO3)

Pipeline overhead arises from the combination of pipeline register delay (setup time plus propagation delay) and clock skew.

6.        What is data path?                                                                                   (CO3)

A datapath is a collection of functional units (such as arithmetic logic units or multipliers, that perform dataprocessing operations), registers, and buses. Along with the control unit it composes the central processing unit (CPU).

7.        Define Register renaming.                                                                       (CO4)

Register renaming is a form of pipelining that deals with data dependences between instructions by renaming their register operands.

8.        Define Commit unit.                                                                                (CO4)

In Tomasulo algorithm, there is an additional stage "Commit". In this stage, the results of instructions will be stored in a register or memory. 

9.        What is cache memory?                                                                           (CO5)

Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to a processor and stores frequently used computer programs, applications and data.

10.     What is Direct mapped cache?                                                                 (CO5)

In Full Associative Mapping Summary, the address is broken into two parts: a tag used to identify which block is stored in which line of the cache (s bits) and a fixed number of LSB bits identifying the word within the block (w bits).
