Test: Types of Processors - Computer Science Engineering (CSE) MCQ

Explanation: The color image of a digital signal processor have multiple channels. The brightness of the pixel is determined by luminance and the color of the pixel is determined by chrominance.

Explanation: RGBA colors has four channels red, green, blue, and alpha, which is transparent.

Explanation: Graphics processing unit is designed to perform calculations in graphics rendering. Intel, NVIDIA, and AMD are dominant providers of GPU.

Explanation: 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.

Explanation: 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 a sequential order.

Explanation: Imperative language is one which executes the program in a sequential order. C program is an example of imperative language, SQL and XQuery are examples of declarative languages or non-imperative language. Concurrent model in HDL is a hardware description language which executes the program concurrently.

Explanation: VLIW is a very long instruction word which 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 in some time. TTA is a transport triggered architecture which is a type of CPU design which 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 used to perform arithmetic and logic operations.

Explanation: 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.

Explanation: 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.

Explanation: In subword parallelism, the wide ALU is divided into smaller slices which enable simultaneous arithmetic and logical operations.

Explanation: Subword parallelism is a form of a vector processing. A vector processor is the one whose instruction set includes operations on multiple data elements simultaneously.

Explanation: Superscalar architecture support out-of-order execution in which the instructions later in the stream are executed before earlier instructions.

Explanation: Pentium 4 is a single core CPU used in desktops, laptops which are proposed by Intel. It has Netburst architecture.

Explanation: The Multicore machine is a combination of many processors on a single chip. The heterogeneous multicore machine also combines a variety of processor types on a single chip.

Explanation: Intel Xeon E7-2850 have ten cores whereas AMD Phenom IIx2 and Intel core cuo has two cores and AMD Phenom IIX3 has three cores.
