The microprocessor is the central processing unit of computers and electronic devices. Early microprocessors included 4-bit and 8-bit processors developed by Intel in the 1970s. Major developments included 16-bit processors like the Intel 8086 and 32-bit processors like the Intel 80386. Modern 64-bit processors include Intel Core i7 and i5. Microprocessors use a central processing unit, memory, and input/output systems to process instructions and data. Microcontrollers integrate a microprocessor with additional components like memory and input/output ports onto a single chip, making them useful for embedded applications.
- A microprocessor is a general purpose programmable logic device that integrates arithmetic and logic unit (ALU), control unit (CU), and registers onto a single chip. It can process data according to programmed instructions and provide output.
- A microprocessor system consists of a microprocessor, memory, input, and output. The microprocessor communicates with these components via a system bus consisting of data, address, and control buses.
- Common applications of microprocessors include computers, test instruments, communications equipment, industrial systems, and aerospace systems. Microprocessors have evolved significantly over time, increasing in capabilities like instruction sets, bandwidth, and clock speed with each new generation.
