1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Which is an imperative language?
A. C program
B. SQL
C. XQuery
D. Concurrent model of HDL
Answer: A
Imperative language is one that executes the program in sequential order. C program is an example of imperative language, SQL and XQuery are examples of declarative languages or non-imperative language. The concurrent model in HDL is a hardware description language that executes the program concurrently.
7. Which of the following instructions supports parallel execution?
A. VLIW
B. TTA
C. ALU operation
D. Test-and-set instructions
Answer: A
VLIW is a very long instruction word that receives many instructions and is executed in one instructed word. VLIW is majorly designed for instruction-level parallel (ILP) that is, it can execute codes concurrently or parallel for some time. TTA is a transport triggered architecture which is a type of CPU design that programs controlling the internal buses of the processor. Test-and-set is used to write to a memory location and return its old values. ALU is used to perform arithmetic and logic operations.
8. Who invented VLIW architecture?
A. Josh Fisher
B. John Ellis
C. John Ruttenberg
D. John O’Donnell
Answer: A
Josh Fisher from Yale Universities invented the concept of VLIW architecture. John Ellis described the VLIW compiler. John Ruttenberg develops some important algorithms in scheduling.
9. What is ILP?
A. instruction-level parallelism
B. instruction-level panel
C. instruction-language panel
D. inter-language parallelism
Answer: A
A processor which supports instruction-level parallelism can perform multiple independent operations in every instruction cycle. Basically, there are four types of instructions. These are CISC instructions, subword parallelism, superscalar, and VLIW.
10. Which ILP supports the ALU division?
A. Subword parallelism
B. CISC
C. Superscalar
D. VLIW
Answer: A
In subword parallelism, the wide ALU is divided into smaller slices which enable simultaneous arithmetic and logical operations.
