	Intel 80386 - Wikipedia, the free encyclopedia
		The Intel 80386 is a microprocessor which was used as the central processing unit (CPU) of many personal computers from 1986 until 1994 and later.
		The predecessor of the 80386 was the Intel 80286, a 16-bit processor with a segment-based memory management and protection system.
		Because of the high degree of compatibility, the range of processors compatible with the 80386 is often collectively termed the i386 architecture; the instruction set for the architecture is now known as IA-32 or, informally, i386.

		De Intel 80386 processor was de opvolger van de 80286 processor.
		In de 16-bits mode werkte de 80386 als een 80286, hij was dus ook compatible met de 8086 processor waarop het populaire MS-DOS draaide.
		De 80386 had geen last meer van de denkfout die in de 80286 wel aanwezig was.

		De Intel 80386 processor was een nog grote sprong voorwaarts dan de 80286 processor.
		In tegenstelling tot zijn voorgangers was de 80386 een 32-bits processor, althans hij had een 32-bits mode meegekregen en als de 80386 in die mode gezet werd dan functioneerde hij als volwaardig 32-bit.
		In de 16-bits modes werkte de 80386 processor als een 80286 processor en was hij dus ook compatible met de 8086 processor waarop het populaire MS-Dos draaide.

		The 80386 architecture takes advantage of this by providing mechanisms to support direct access to the instructions and data of the current module's environment, with access to additional segments on demand.
		The 80386 fetches all instructions from this code segment, using as an offset the contents of the instruction pointer.

		Intel later introduced the 80486, but neither it nor its successors under the Pentium name were as big a step for Intel as the 32-bit flat addressing made possible by the 80386 (other microprocessor architectures, such as the Motorola 68000, had long since supported this form of addressing).

		There is no chance that we would provide an 80386 CPU emulation on the current ARM based Nokia and Psion products.
		It would be a lot slower than the current 80186 emulation, and would also take up more space on disk and in memory.
		However, you should note that the reason many programs need an 80286 or 80386 processor is because they need more memory space than they can access using the 1 megabyte address space of the basic 80186 architecture.

		In the 80286 and 80386, however, there are software-only methods to give the same functionality as EMS hardware.
		Memory managers are written to run on the (standard) 80386 and not some particular vendor's EMS hardware.
		In fact, it is usually faster than true EMS cards because: the circuitry is onboard the CPU chip; the 80386 is faster than lower-class machines that usually use EMS cards; and the extended memory used is often fast, 32-bit system memory rather than card-based memory which is slowed down by the relatively slow I/O bus.

		In the unlikely event that any software depends on this anomaly, the same effect can be simulated on the 80386 by using paging to map the first 64K bytes of the 17th megabyte of logical addresses to physical addresses in the first megabyte.
		Other values that were invalid on for the 80286 may be valid for the 80386 because of the additional descriptor types defined by the 80386.
		With the 80386, the defined area of memory is guaranteed to be locked against access by a processor executing a locked instruction on exactly the same memory area, i.e., an operand with identical starting address and identical length.

		The INTEL 80386 CPU, or i386 for short, was at the heart of the PC's on which the first Linux systems were developed.
		Intel's definitive 16-bit processor, the 80286, went some of the way to addressing the problems, but still fell far short of the features found in the mini computers which were typically being used to run Unix like operating systems.
		Although the 80386 systems were capable of running existing 16-bit DOS and Windows programs, these new powers allowed the PC to run more powerful operating systems, and led to the development of new operating systems such as Windows NT and, of course, Linux (see History).

		Much has been said recently about the introduction of the Intel 80386SX or P9, but as usual little has been said about the real benefits of the 80386SX, and where it fits into the new generation of personal computers and PC based solutions that are coming our way.
		Many software developers are already recognising this and producing 386 versions of their software to make use of the full potential and performance of the 386.
		However, the performance difference between the 80386 and the 80386SX is not as great as that between the 8086 and the 8088.

		One possible solution is to determine the processor type at run time and execute different sections of code in the program depending on the presence or absence of a 386 or later CPU.
		A second possibility is to write two versions of the code, one that uses only 8086 instructions and one that uses the full 80386 instruction set.
		Since both versions of the code appear in the same source file, the program will be much easier to maintain since you will not have to correct the same bug in two separate source files.
