- Intel_iAPX_432 abstract "The iAPX 432 (Intel Advanced Performance Architecture) was Intel's first 16-bit and 32-bit microprocessor design, introduced in 1981 as a set of three components. It was intended to be Intel's major design for the 1980s, implementing many advanced multitasking and memory management features. The design was therefore referred to as a Micromainframe. Its instruction set architecture was an entirely new design and a significant departure from previous Intel microprocessors such as 8008 and 8080. The iAPX 432 programming model was a stack machine with no visible general purpose registers. iMAX 432 was the name of an operating system written for running on iAPX 432.Originally designed for clock frequencies of up to 10 MHz, actual devices sold were specified for maximum clock speeds of 4 MHz, 5 MHz, 7 MHz and 8 MHz respectively with a peak performance of 2 million instructions per second at 8 MHz.The iAPX 432 was "designed to be programmed entirely in high-level languages", with Ada being primary and it supported object-oriented programming and garbage collection directly in hardware and microcode. Direct support for various data structures was also intended to allow modern operating systems for the iAPX 432 to be implemented using far less program code than for ordinary processors. These properties and features resulted in a hardware and microcode design that was much more complex than most processors of the era, especially microprocessors.Using the semiconductor technology of its day, Intel's engineers weren't able to translate the design into a very efficient first implementation. Along with the lack of optimization in a premature Ada compiler, this contributed to rather slow but expensive computer systems, performing typical benchmarks at roughly 1/4 the speed of the new 80286 chip at the same clock frequency (in early 1982)[1].[citation needed]This initial performance gap to the rather low profile and low priced 8086-line was probably the main reason why Intel's plan to replace the latter (later known as x86) with the iAPX 432 failed. Although engineers saw ways to improve a next generation design, the iAPX 432 Capability architecture had now started to be regarded more as an implementation overhead rather than as the simplifying support it was intended to be.The iAPX 432 project was a commercial failure for Intel.".
