80386 Microprocessor is a 32-bit processor that holds the ability to carry out 32-bit operations in one cycle. It has a data and address bus of 32-bit each. Thus has the ability to address 4 GB (or 232) of physical memory. Multitasking and protection capability are the two key characteristics of the 80386 microprocessor. 80386 …
80286 Microprocessor is a 16-bit microprocessor that has the ability to execute 16-bit instruction at a time. It has non-multiplexed data and address bus. The size of data bus is 16-bit whereas the size of address bus is 24-bit. It was invented in February 1982 by Intel. 80286 microprocessor was basically an advancement of 8086 …
PIC is an abbreviation used for Peripheral Interface Controller. PIC microcontroller is the smallest microcontroller in the world and are programmed to execute large number of operations. These were initially designed to support PDP (programmed data processor) computers, for controlling the peripheral devices. It is based on RISC architecture. PIC microcontrollers hold the ability of …
Definition: DMA or Direct Memory Access Controller is an external device that controls the transfer of data between I/O device and memory without the involvement of the processor. It holds the ability to directly access the main memory for read or write operation. DMA controller was designed by Intel, to have the fastest data transfer …
An instruction is a binary command used to execute an operation inside the microprocessor over a given data. A group of instructions that are supported by the 8085 microprocessor is known to be the instruction set of 8085 microprocessor. Basically, 8085 is designed to have 5 functional categories of the instruction set. Here in this …
Definition: 8051 is an 8-bit microcontroller that contains 40 pins of dual-in-line packaging. Out of the 40 pins, 32 pins are allotted to I/O ports. However, in 8051 there exist multiple pins which are assigned more than one signal. We have already discussed the architecture and working of 8051 microcontrollers. In the working, we have …

8051 microcontroller is an 8-bit microcontroller created in 1981 by Intel Corporation. It has an 8-bit processor that simply means that it operates on 8-bit data at a time. It is among the most popular and commonly used microcontroller. As it is an 8-bit microcontroller thus has 8-bit data bus, 16-bit address bus. Along with …
Definition: Vector processor is basically a central processing unit that has the ability to execute the complete vector input in a single instruction. More specifically we can say, it is a complete unit of hardware resources that executes a sequential set of similar data items in the memory using a single instruction. We know elements …
Definition: 8086 is a 16-bit microprocessor and was created by Intel in 1978. Like the pin configuration of 8085 microprocessor, the 8086 microprocessor also contains 40 pins dual in line. However, unlike the 8085 microprocessor, an 8086 to have better performance, operates in 2 modes that are minimum and maximum mode. The minimum mode is a single …
