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.

The 80960Hx is not “drop-in” compatible in an 80960Cx-based system. Customers can design systems that accept either 80960Hx or Cx

processors.
