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 80960Hx Processor

The Intel 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 may run at the bus speed or faster using Intel’s clock multiplying technology

(see 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.
