Just How Bad Was The Intel IAPX432?
Summary
The article reviews the Intel iAPX432 historical architecture, noting its hyper CISC design, the lack of general purpose registers, and a controversial benchmark that suggests compiler optimization may have limited its performance more than the hardware. It places the chip in a broader arc of computer architecture history and references an open source SBC project for the iAPX432, as well as comparisons to Itanium.
