1.What is a Microprocessor?
The microprocessor is a CPU manufactured in a single device controlled by a chip program, which collects instructions from memory, decodes and executes instructions. Three basic characteristics differentiate the microprocessor.
• Instruction Set: The instruction set of the microprocessor can be executed.
• Bandwidth: The number of bits processed in a single instruction
• Clock speed: Given in MHz Megahertz, the clock speed determines how many instructions per second the processor can execute.
In addition to this, the microprocessors are classified as RISC (Reduced Instruction Set Computer) or CISC (Complex Instruction Set Computer).
2. What are the basic microprocessor units?
The basic units or microprocessor block are ALU, a Records Array and control unit.
Let's give examples for an 8/16/32 bit microprocessor?
• 8-bit processors - 8085, Z80, 6800
• 16-bit processors: 8086, 68000, Z8000
• 32-bit processors - 80386, 80486
• 64-bit processors: Intel 64 (x64), AMD64, IBM (Power PC), SUN (SPARC).
3. What are 1st / 2nd / 3rd / 4th generation processors?
The processors of PMOS, NMOS, HMOS, HCMOS technology are called 1st / 2nd / 3rd / 4th generation processors and consist of 4, 8, 16 and 32 bits.
4. What is the speed of the microprocessor?
The speed of the microprocessor depends on several factors, such as data bus width (number of instructions processed) and clock speed.
5. What is Software and Hardware?
The software is a set of instructions or commands necessary to perform a specific task using a programmable device or computer. The hardware refers to the component or device used to form a computer machine in which the software can be run and tested. No software hardware is the idle machine.
6. Distinguish between microprocessor and microcontroller?
The microprocessor is a digital integrated circuit that can be programmed with a series of instructions to perform a function specified in the data. The microcontroller is small small computer on the single integrated circuit, which has memory, I / O on the chip itself. So we can say that the microprocessor can perform few functions but the microcontroller can perform many functions.
7. What are the disadvantages of the microprocessor?
The microprocessor has limitations on the size of the data. Most microprocessors do not support floating-point operations.
8. What is the difference between microprocessor and microcontroller?
In the microprocessor plus op codes, few bits handling instructions, but in the microcontroller: less op codes and more bits handling instructions also microcontroller defined as a device that includes microprocessor, memory and signal lines of input and output in a Chip only.
9. What is an Instruction?
An instruction is an order given to a computer processor by a computer program. At the lowest level, each set of instructions is a sequence of 0s and 1s that describes a physical operation that the computer must perform (such as "Add") and, depending on the type of particular instruction, the specification of special storage areas called Records that may contain The data is used in the execution of the instruction or the location in the computer memory of the data.
10. What is the clock cycle?
The speed of the computer processor is determined by the clock cycle, which is the amount of time between two pulses of an oscillator. In general, the higher the number of pulses per second the faster the computer processor will be able to process the information.
