About This Document
This document describes the parametric performance of Intel’s 80960Hx embedded superscalar
microprocessors. Detailed descriptions for functional topics — other than parametric performance
— are published in the i960® Hx Microprocessor User’s Guide (272484).
In this document, “80960Hx” and “i960 Hx processor” refer to the products described in Table 1.
Throughout this document, information that is specific to each is clearly indicated.

Intel’s 80960Hx Processor
Intel’s 80960Hx processor provides new performance levels while maintaining backward
compatibility (pin1 and software) with the i960 CA/CF processor. This newest member of the family
of i960 32-bit, RISC-style, embedded processors allows customers to create scalable designs that
meet multiple price and performance points. This is accomplished by providing processors that can
run at the bus speed or faster using Intel’s clock multiplying technology (Table 1).The 80960Hx core
is capable of issuing 150 million instructions per second, using a sophisticated instruction scheduler
that allows the processor to sustain a throughput of two instructions every core clock, with a peak
performance of three instructions per clock. The 80960Hx-series comprises three processors, which
differ in the ratio of core clock speed to external bus speed.

processors.
