21. Where is the trap vector table located in the SPARC processor?
A. program counter
B. Y register
C. status register
D. trap base register
Answer: D
The trap vector table is located in the trap base register which supplies the address of the service routine. When it is completed REIT instructions are executed.
22. How many bits does the SPARC-V9 processor have?
A. 16
B. 32
C. 64
D. 128
Answer: C
There are three major versions of SPARC which are SPARC-V7, SPARC-V8, and SPARC-V9. The former two are 32 bits processors and the latter is a 64-bit processor.
23. What are the three modules in the SPARC processor?
A. IU, FPU, CU
B. SP, DI, SI
C. AX, BX, CX
D. CU, CH, CL
Answer: A
The SPARC processor has three modules which are the Integer unit, a Floating point unit and a coprocessor unit. Each module has its own functions and an integer unit controls the overall operation of the processor.
24. How many floating-point registers does the FPU of the SPARC have?
A. 16 128-bit
B. 32 128-bit
C. 64 128-bit
D. 10 128-bit
Answer: A
It possesses 32 32-bit single-precision, 32 64-bit double-precision, and 16 128-bit quads precise floating registers.
25. Which module of SPARC contains the general-purpose registers?
A. IU
B. FPU
C. CU
D. control unit
Answer: A
The integer unit contains the general-purpose registers and it controls the overall operation and performance of the processor and the memory address is also calculated by the integer unit.
26. What shows the brightness of the pixel in a digital signal processor?
A. luminance
B. transparent
C. chrominance
D. opaque
Answer: A
The color image of a digital signal processor has multiple channels. The brightness of the pixel is determined by luminance and the color of the pixel is determined by chrominance.
27. What is the color format of chrominance in a digital signal processor?
A. VGBA
B. VIBGYOR
C. White
D. RGBA
Answer: D
RGBA colors have four channels red, green, blue, and alpha, which is transparent.
28. Which of the following processor are designed to perform calculations in graphics rendering?
A. GPU
B. digital signal processor
C. microprocessor
D. microcontroller
Answer: A
The Graphics processing unit is designed to perform calculations in graphics rendering. Intel, NVIDIA, and AMD are dominant providers of GPU.
29. Which of the processor is a good match for applications such as video games?
A. GPU
B. VLIW
C. Coprocessor
D. Microcontroller
Answer: A
GPU is a graphics processing unit. Therefore, more graphical images can be created by GPU which is necessary for video games. Therefore, GPU is a good match for video games.
30. Which of the following statement is true for concurrency?
A. different parts of the program executes physically
B. different parts of the program execute sequentially
C. different parts of the program execute conceptually
D. different parts of the program execute sequentially and physically
Answer: C
A concurrent program executes different parts of the program conceptually, a parallel program executes different programs physically and a non-concurrent program executes the program in sequential order.
