AMD 80386 microprocessor family
In 1987 Intel cancelled 1982 technical exchange agreement between Intel and AMD. As a result of this cancellation AMD didn't get rights to produce 80386 microprocessors. In 1987 AMD began long arbitration process that lasted 5 years, and ended only in 1992. In the meantime AMD used their rights to use Intel's microcode, granted them by 1976 cross-license agreement (extended in 1982), to reverse-engineer Intel 80386 microprocessor and 80287 co-processor. The process of reverse-engineering of Intel 80386 started in 1988 and lasted more than a year. In the result AMD came up with more efficient microprocessor that still used Intel's microcode. AMD 80386 family was released in 1990. In 1991, AMD introduced 80386SX microprocessors.
