Encyclopedia > Intel 80188

The Intel 80188 is a version of the Intel 80186 microprocessor with an 8 bit external data bus, instead of 16 bit. This makes it less expensive to connect to peripherals. An Intel 80186 Microprocessor The 80186 architecture. ... In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. ... For an account of the words periphery and peripheral as they are used in biology, sociology, politics, computer hardware, and other fields, see the periphery disambiguation page. ...


As the 8086, the 80188 featured four 16-bit general registers, which could also be accessed as eight 8-bit registers. It also included six more 16-bit registers, which included, for example, the stack pointer, the instruction pointer, index registers, or a status word register that acted like a flag, for example, in comparison operations. The 8086 is a 16-bit microprocessor chip designed by Intel in 1978, which gave rise to the x86 architecture. ... In computer architecture, a processor register is a small amount of very fast computer memory used to speed the execution of computer programs by providing quick access to commonly used values—typically, the values being in the midst of a calculation at a given point in time. ... A stack is a data structure that works on the principle of Last In First Out (LIFO). ... The program counter (also called the instruction pointer in some computers) is a register in a computer processor which indicates where the computer is in its instruction sequence. ... An index register in a computer CPU is a processor register used for modifying operand addresses during the run of a program, typically for doing vector/array operations. ...


Just like the 8086, the processor also included four 16-bit segment registers that enabled the addressing of more than 64 Kbytes of memory, which is the limit of a 16-bit architecture, by introducing an offset value that was added, after being shifted left 4 bits, to the value of another register. This addressing system provided a total of 1 Mbyte of addressable memory, a value that, at the time, was considered to be very far away from the total memory a computer would ever need. The 8086 is a 16-bit microprocessor chip designed by Intel in 1978, which gave rise to the x86 architecture. ... On the Intel x86 architecture, a memory segment is the portion of memory which may be addressed by a single index register without changing a 16-bit segment selector. ...

Intel 80188 family (0 words)
Intel 80188 microprocessor is an enhanced version of Intel 8088 processor.
With the exception of integrated components, the 80188 microprocessor is not very different from the 8088, and, because of this, it may be considered as an embedded version of the 8088.
The Intel 80188 didn't even have its own version of co-processor and worked with Intel 8087.
