What is a microprocessor?

Microprocessor A microprocessor is a computer processor on a microchip. It contains all the essential components and need RAM memory only. Some Microprocessors also hold the…ir own RAM ("Random Access Memory"). A microprocessor is designed to perform arithmetic and logic operations that make use of data on the chip and data in RAM. Typical microprocessor operations include adding, subtracting, comparing two numbers, and jumping in the instruction set. These operations are the result of the code produced. When the computer is turned on, the microprocessor is designed to get the first instruction from the Basic Input/Output System (BIOS) that comes with the computer. After that, either the BIOS, or the operating system that BIOS loads into computer memory, or an application program is "driving" the microprocessor, giving it instructions to perform. A microprocessor computes instructions depending on how fast the processor is designed and if the processor's clock crystal (think of the clock crystal as a metronome). The faster (in mHz or gHz) the processor and its clock crystal are, the better. Processors currently come in 8, 16, 32 and 64 bit versions. AMD, Intel and VIA are the three leading processor manufacturers. On e.g. washing machines, you can make all the logic needed with a simple 8 bit system that holds all operating system and programs on the chip. More sophisticated may need 16 bit. There is one down-side to using many bits for data, and that is that the more you have to load into the microprocessor, the longer time will it take, and the slower will you perceive that the device is - unless someone is cheating and does things for more than one at a time. You have the option of buying a traditional single-core processor, or the newer technology: dual/duo or quad core processors. These technologies essentially contain two or four or more CPU that share the same cache, which enable more instructions to be executed. The faster the clock cycle is, the more heat will the microprocessor require. The alternative is to change technology - chemistry and use denser circuits. CMOS operate at 1.6V and require very little to blow the device to kingdom come. But this is the dominant technology. Faster switching may be achieved by e.g. SOS, advance nMOS but will require more power. The speed of the light limits the clock frequency that is used. So 2GHz makes the distance the electricity travels between during each cycle around 17cm or 7". Placing more on the actual microprocessor, and reduce the number of bits and thus the complexity, is a simple way to make devices run faster and more reliable. A microprocessor is an integral circuit that acts as the main processing unit of a computer. Known as the "brain" of the computer it carries out instructions, performs calculations and interacts with the components which operate the machine.

What does a microprocessor do?

A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC, or microchip). It is a multipurpose, programmable…, clock-driven, register based electronic device that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. To understand how a microprocessor works, it is helpful to look inside and learn about the logic used to create one. You can also learn about assembly language - the native language of a microprocessor - and many of the things that engineers can do to boost the speed of a processor. A microprocessor executes a collection of machine instructions that tell the processor what to do. Based on the instructions, a microprocessor does three basic things: . Using its ALU (Arithmetic/Logic Unit), a microprocessor can perform mathematical operations like addition, subtraction, multiplication and division. Modern microprocessors contain complete floating point processors that can perform extremely sophisticated operations on large floating point numbers. . A microprocessor can move data from one memory location to another . A microprocessor can make decisions and jump to a new set of instructions based on those decisions. There may be very sophisticated things that a microprocessor does, but those are its three basic activities. This is about as simple as a microprocessor gets. This microprocessor has: . an address bus (that may be 8, 16 or 32 bits wide) that sends an address to memory . a data bus (that may be 8, 16 or 32 bits wide) that can send data to memory or receive data from memory . a RD (Read) and WR (Write) line to tell the memory whether it wants to set or get the addressed location . a clock line that lets a clock pulse sequence the processor . A reset line that resets the program counter to zero (or whatever) and restarts execution. Let's assume that both the address and data buses are 8 bits wide in this example. Here are the components of this simple microprocessor: . Registers A, B and C are simply latches made out of flip-flops. . The address latch is just like registers A, B and C. . The program counter is a latch with the extra ability to increment by 1 when told to do so, and also to reset to zero when told to do so. . The ALU could be as simple as an 8-bit adder (See the section on adders in How Boolean Logic Works for details), or it might be able to add, subtract, multiply and divide 8-bit values. Let's assume the latter here. . The test register is a special latch that can hold values from comparisons performed in the ALU. An ALU can normally compare two numbers and determine if they are equal, if one is greater than the other, etc. The test register can also normally hold a carry bit from the last stage of the adder. It stores these values in flip-flops and then the instruction decoder can use the values to make decisions. . There are 6 boxes marked "3-State" in the diagram. These are tri-state buffers . A tri-state buffer can pass a 1, a 0 or it can essentially disconnect its output (imagine a switch that totally disconnects the output line from the wire the output is heading toward). A tri-state buffer allows multiple outputs to connect to a wire, but only one of them to actually drive a 1 or a 0 onto the line. . The instruction register and instruction decoder are responsible for controlling all of the other components. There would also be control lines from the instruction decoder that would: . Tell the A register to latch the value currently on the data bus. . Tell the B register to latch the value currently on the data bus. . Tell the C register to latch the value currently on the data bus. . Tell the program counter register to latch the value currently on the data bus. . Tell the address register to latch the value currently on the data bus. . Tell the instruction register to latch the value currently on the data bus. . Tell the program counter to increment . Tell the program counter to reset to zero . Activate any of the 6 tri-state buffers (6 separate lines) . Tell the ALU what operation to perform . Tell the test register to latch the ALUs test bits . Activate the RD line . Activate the WR line Coming into the instruction decoder are the bits from the test register and the clock line, as well as the bits from the instruction register.
