A microprocessor is a integrated circuit semiconductor chip that combines the instruction-handling, arithmetic, and logical operations of a computer on a single semiconductor integrated circuit. A microprocessor system typically includes a central processor unit (CPU), memory subsystem and input/output subsystem to permit the system to communicate with the outside world. Typical microprocessors have registers, arithmetic logic units, memory, input/output circuits and other similar components which are hard wired together. A microprocessor as a main element in the microprocessor system is connected to memories or peripheral units via a data bus, an address bus, and a control bus. A microprocessor comprises an external and/or internal memory indicated by means of alignment boundaries for storing data. An arithmetic-logic unit (ALU) carrying out calculations in the microprocessor employs registers to temporarily store the data to be processed in the calculations. Data is transferred according to need between the memory and the register. A microprocessor includes a datapath portion and a control portion. Data and addresses are manipulated in the datapath portion. The control portion is operative to decode instructions in a program into a form suitable for controlling that manipulation. Programs typically are stored in a main memory external to the chip and include sequences of instructions and data at specified addresses in the memory. Microprocessors include a cache memory which stores a subset of data stored in other memories of the computer system. When the processor executes an instruction that references data, the processor first checks to see if the data is present in the cache. Microprocessors can be grouped into two general classes, general-purpose microprocessors designed to be programmable by the user to perform any of a wide range of tasks, and special-purpose microprocessors designed to be programmable by the user to perform any of a wide range of tasks. Microprocessor architectures may generally be classified as either complex instruction set computing (CISC) architectures or reduced instruction set computing (RISC) architectures.
