The [2] also called iAPX 86 [3] is a bit microprocessor chip designed by Intel between early and June 8, , when it was released. The Intel , released July 1, , [4] is a slightly modified chip with an external 8-bit data bus allowing the use of cheaper and fewer supporting ICs [note 1] , and is notable as the processor used in the original IBM PC design, including the widespread version called IBM PC XT. The gave rise to the x86 architecture , which eventually became Intel's most successful line of processors. In , Intel launched the , the first 8-bit microprocessor. The device needed several additional ICs to produce a functional computer, in part due to it being packaged in a small pin "memory package", which ruled out the use of a separate address bus Intel was primarily a DRAM manufacturer at the time. Two years later, Intel launched the , [note 3] employing the new pin DIL packages originally developed for calculator ICs to enable a separate address bus. It has an extended instruction set that is source-compatible not binary compatible with the [5] and also includes some bit instructions to make programming easier.

Users of the long ago realized, in hindsight, that the processor makes very efficient use of its memory. By having a large number of 8-bit object codes, the produces object code as compact as some of the most powerful minicomputers on the market at the time.

If the is to retain 8-bit object codes and hence the efficient memory use of the , then it cannot guarantee that bit opcodes and data will lie on an even-odd byte address boundary. The first 8-bit opcode will shift the next 8-bit instruction to an odd byte or a bit instruction to an odd-even byte boundary. By implementing the BHE signal and the extra logic needed, the allows instructions to exist as 1-byte, 3-byte or any other odd byte object codes. Simply put: If memory addressing is simplified so that memory is only accessed in bit units, memory will be used less efficiently.

Intel decided to make the logic more complicated, but memory use more efficient. This was at a time when memory size was considerably smaller, and at a premium, than that which users are used to today. Small programs could ignore the segmentation and just use plain bit addressing. This allows 8-bit software to be quite easily ported to the The data block is copied one byte at a time, and the data movement and looping logic utilizes bit operations.

The code above uses the BP base pointer register to establish a call frame , an area on the stack that contains all of the parameters and local variables for the execution of the subroutine. This kind of calling convention supports reentrant and recursive code, and has been used by most ALGOL-like languages since the late s.

The above routine is a rather cumbersome way to copy blocks of data. The provides dedicated instructions for copying strings of bytes. These instructions assume that the source data is stored at DS: SI, the destination data is stored at ES: DI, and that the number of elements to copy is stored in CX.

The above routine requires the source and the destination block to be in the same segment, therefore DS is copied to ES. The loop section of the above can be replaced by:. This copies the block of data one byte at a time. Alternatively the MOVSW instruction can be used to copy bit words double bytes at a time in which case CX counts the number of words copied instead of the number of bytes. This routine will operate correctly if interrupted, because the program counter will continue to point to the REP instruction until the block copy is completed.

The copy will therefore continue from where it left off when the interrupt service routine returns control. Although partly shadowed by other design choices in this particular chip, the multiplexed address and data buses limit performance slightly; transfers of bit or 8-bit quantities are done in a four-clock memory access cycle, which is faster on bit, although slower on 8-bit quantities, compared to many contemporary 8-bit based CPUs. As instructions vary from one to six bytes, fetch and execution are made concurrent and decoupled into separate units as it remains in today's x86 processors: The bus interface unit feeds the instruction stream to the execution unit through a 6-byte prefetch queue a form of loosely coupled pipelining , speeding up operations on registers and immediates , while memory operations became slower four years later, this performance problem was fixed with the and However, the full instead of partial bit architecture with a full width ALU meant that bit arithmetic instructions could now be performed with a single ALU cycle instead of two, via internal carry, as in the and , speeding up such instructions considerably.

Combined with orthogonalizations of operations versus operand types and addressing modes , as well as other enhancements, this made the performance gain over the or fairly significant, despite cases where the older chips may be faster see below. As can be seen from these tables, operations on registers and immediates were fast between 2 and 4 cycles , while memory-operand instructions and jumps were quite slow; jumps took more cycles than on the simple and , and the used in the IBM PC was additionally hampered by its narrower bus.

The reasons why most memory related instructions were slow were threefold:. However, memory access performance was drastically enhanced with Intel's next generation of family CPUs.

The and both had dedicated address calculation hardware, saving many cycles, and the also had separate non-multiplexed address and data buses. The Intel was the standard math coprocessor for the and , operating on bit numbers. Manufacturers like Cyrix compatible and Weitek not compatible eventually came up with high-performance floating-point coprocessors that competed with the , as well as with the subsequent, higher-performing Intel Such relatively simple and low-power compatible processors in CMOS are still used in embedded systems.

The electronics industry of the Soviet Union was able to replicate the through both industrial espionage and reverse engineering [ citation needed ]. The resulting chip, KVM86 , was binary and pin-compatible with the No 4,, GB-A, Published June 28, From Wikipedia, the free encyclopedia.
