Explain the operation of a micro programmed control unit with the help of a diagram. 8m Jun2008 THE MICRO-PROGRAMMED CONTROL The logic of the control unit is specified by a micro-program. A micro-program is also called firmware (midway between the hardware and the software). It consists of: (a) One or more micro-operations to be… Read More »
Explain the basic principle of Quine-McCluskey method of simplifying the Boolean expression with the help of an example function. 6m Jun2007 Quine McKluskey Method A tabular method was suggested to deal with the increasing number of variables known as Quine McKluskey Method. This method is suitable for programming and hence provides a tool for automating… Read More »
Explain the process of handling an interrupt that occurs during the execution of a program, with the help of an example. 9m jun2006 Interrupt Handling and Instruction Cycle On the occurrence of an interrupt, an interrupt request (in the form of a signal) is issued to the CPU. The CPU on receipt of interrupt… Read More »
Explain any five addressing modes used in an 8086 microprocessor, with the help of an example of each. 5m jun2006 The following tree shows the common addressing modes: In general not all of the above modes are used for all applications. However, some of the common areas where compilers of high-level languages use them are:… Read More »
Explain the working of the instruction pipelining, with the help of a diagram 5m Dec2005 INSTRUCTION PIPELINING To extract better performance instruction execution can be done through instruction pipeline. The instruction pipelining involves decomposing of an instruction execution to a number of pipeline stages. Some of the common pipeline stages can be instruction fetch (IF),… Read More »
Explain the following with the help of a suitable diagram or an example. Error detection and correction process 5m Dec2005 Error Detection and Correction Codes: The code, which helps in recognition and correction of errors Computer is an electronic media; therefore, there is a possibility of errors during data transmission. Such errors may result from… Read More »
Explain the following with the help of a suitable diagram or an example. Evaluation stack architecture 5m Dec2005 A stack is a data structure that implements Last-In-First-Out (LIFO) access policy. You could add an entry of data (or value) to the stack with a PUSH (value) Function and remove an entry of data (or value) from the… Read More »
Explain the following with the help of a suitable diagram or an example:- Parameter passing using stack in 8086 assembly language 5m Dec2005 Most HLLs use the stack to pass parameters because this method is fairly efficient. To pass parameters on the stack, push them immediately before calling the subroutine. The subroutine then reads this data… Read More »
