The complex history of the Intel i960 RISC processor

The Intel i960 was a remarkable 32-bit processor of the 1990s with a confusing set of versions. Although it is now mostly forgotten (outside the many people who used it as an embedded processor), it has a complex history. It had a shot at being Intel's flagship processor until x86 overshadowed it. Later, it was the world's best-selling RISC processor. One variant was a33-bit processor with a decidedly non-RISC object-oriented instruction set; it became a military standard and was used in the F-22 fighter plane. Another version powered Intel's short-lived Unix servers. In this blog post, I'll take a look at the history of the i960, explain its different variants, and examine silicon dies. This chip has a lot of mythology and confusion (especially onWikipedia), so I'll try to clear things up.

Not even Intel can overcome x86 - and I can guarantee you: neither will ARM. The truth is that x86 simply cannot die.
