Why is microprocessor 16-bit?
16/32-bit Motorola 68000 and Intel 386SX The Motorola 68000 is sometimes called 16-bit because of the way it handled basic mathematics. The instruction set was based on 32-bit numbers and the internal registers were 32 bits wide, so by common definitions, the 68000 is a 32-bit design.
What do you mean by 8 bit and 16-bit microprocessor?
The main difference between 8 bit and 16 bit microcontrollers is the width of the data pipe. As you may have already deduced, an 8 bit microcontroller has an 8 bit data pipe while a 16 bit microcontroller has a 16 bit data pipe. Another key difference between 8 bit and 16 bit microcontrollers is in their timers.
What is bit microprocessor?
A bit (short for “binary digit”) is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1. Additionally, bits are also used to describe processor architecture, such as a 32-bit or 64-bit processor.
Which is a 16-bit register in 8085 microprocessor?
Stack Pointer
Stack Pointer: The stack pointer in the 8085 microprocessor is a 16-bit register that stores the address of the top of stack memory. The value of the stack pointer is decremented by 2 in PUSH operation. It will increment by 2 in POP operation.
What is difference between 8-bit and 16-bit?
The main difference between an 8 bit image and a 16 bit image is the amount of tones available for a given color. An 8 bit image is made up of fewer tones than a 16 bit image. This means that there are 256 tonal values for each color in an 8 bit image. …
What is the difference between 8 and 16-bit?
To help understand the scale of bit depth difference between 8 and 16-bit images, picture an 8-bit image as a 256-foot-tall building. In terms of color, an 8-bit image can hold 16,000,000 colors, whereas a 16-bit image can hold 28,000,000,000.
What are 16 bit graphics?
16-bit graphics means High color , a color palette of 65,536 available colors for each pixel. it’s unessential for games to use the full high color 16-bit graphics, even 15-bit High Color with 32,768 possible colors for each pixel was rare, but more common.
What is a group of 16 bits?
word
The correct answer is a word. A combination of 16 bits is called a word.
What is a 16-bit register?
In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets or 2 Bytes) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. So as a result, 16-bit register can store 216 different values.
Which of the following are 16-bit register?
DPTR is the only 16-bit register available and is often used to store 2-byte values.
What is different between 16 bit and 32 bit microcontroller?
An n bit micro controller operates on n bits at a time. so a 16 bit and 32 bit micro controllers operates on 16 and 32 bits respectively at a time. The difference between the two microcontrollers is the number of bits on which they operate on.
What are the types of microprocessor?
There are two different types of microprocessors; they are ARM processors and X86 processors. X86 processors are named for the instruction set they use, while ARM processors are named after the company that designs them.
What is an example of a microprocessor?
An example of microprocessor architecture. The microprocessor contains the arithmetic logic unit (ALU) and the control unit for a microcomputer. It is connected to memory and I/O by buses which carry information between the units.
What is 8086 microprocessor?
Answer Wiki. 8086 is Microprocessor launced by Intel in 1976. 8086 is 16bit Microprocessor external 8-bit data bus and is notable as the processor used in the original IBM PC design, including the widespread version called IBM PC XT .
