microprocessors. Detailed descriptions for functional topics, other than parametric performance,
are published in the i960

Intel 80960Hx Processor
The Intel 80960Hx processor provides new performance levels while maintaining backward
compatibility (pin
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
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.
† Processor inputs are 5 V tolerant.
