The term 16-bit means that its arithmetic logic unit, internal registers and most of its instructions are designed to work with 16-bit binary words.The 8088, however, has an 8-bit data bus, soil can only read data from or write data to memory and ports 8 bits at a time.
Each of the 10, 48, 576 memory locations is byte Therefore, a sixteen-bit words are stored in two consecutive memory locations. The 8088 also has a 20-bit address bus, so it can also address 2 20 or 10, 48, 576 memory locations. It performs the arithmetic and logical operations on bit, byte, word and decimal numbers including multiply and divide. ![]() In this mode the CPU issues the control signals required by memory and IO In multiprocessor (more than one processor in the system) system 8086 operates in maximum mode. In maximum mode, control signals are generated with the help of external bus controller (8288). Difference Between 8086 And 80386 Microprocessor Code For TwoIn multiprogramming, the code for two or more processes is in memory at the same time and is executed in a time-multiplexed fashion. This 8085 microprocessor tutorial covers following sub-topics: 8085 architecture. ![]() Following are the features of 8086 microprocessor: Data Bus Width: 16 Addressed Memory Size of: 1M. Following are the features of 80286 microprocessor: Data bus width: 16 Addressed Memory size of: 16M Clock speed is higher and hence some instructions. As shown in the figure, 80286 does not have multiplexed addressdata bus lines. Following are the features of 80386 microprocessor: 32-bit data bus and 32-bit memory address It addresses up to 4G bytes of memory. SX: address 16M bytes of memory. SL: address 32M bytes of memory. SLC: address 32M bytes of memory.It contain internal. Difference Between 8086 And 80386 Microprocessor 32 Bit Address BusFollowing are the features of 80486 microprocessor: Data Bus Width: 32 bit Address bus: 32 bit Memory Size: 4G 16K cache The 80486 architecture has been ungraded such that. Following table compares 80286 vs 80386 vs 80486 and mentions difference between them.
