CS401 Computer Architecture and Assembly Language Programming Final Paper March 2014

All the mcqs were from past papers solved by moaaz .. and subjective part is here 1) For which purpose INT 1 is used & describe the functionality of this interrupt
2) write the four main character of sun SPARC processor
3) write the interrupt number for BIOS disk service
4) which two I/O ports are designated for interrupt controller
5) The following code is written in C program write it in assembly language
“Int subtract (int x,int y)”
6)how many routines required to be defined by a device driver write their names also.
7) why INT and flags are cleared?
8) in order to terminate program we can use 4C or service 31 of INT , explain how it works.
9) write the different register setting for memory allocation using int 21 service
10) write the service following codes providing
Mov si,12
Mov al ,[cs:si]
Mov [opcode],al
Mov byte [cs:si],0*CC
11) write the code for disable sound card of system using PIC post in assembly language
12)the following code is written in C language write the code in assembly language
“Int multiply (int x,int y);”
