80960HA/HD/HT 1.0 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.

80960HA/HD/HT In addition to expanded clock frequency options, the 80960Hx provides essential enhancements for an emerging class of high-performance embedded applications. Features include a larger instruction cache, data cache, and data RAM than any other 80960 processor to date. It also boasts a 32-bit demultiplexed and pipelined burst bus, fast interrupt mechanism, guarded memory unit, wait state generator, dual programmable timers, ONCE and IEEE 1149.1-compliant boundary scan test and

80960HA/HD/HT subsystems with minimum system complexity. To reduce the effect of wait states, the bus design is decoupled from the core. This lets the processor execute instructions while the bus performs memory accesses independently. The Bus Controller’s key features include: • Demultiplexed, Burst Bus to support most efficient DRAM access modes • Address Pipelining to reduce memory cost while maintaining performance • 32-, 16- and 8-bit modes to facilitate I/O interfacing • Full internal w

80960HA/HD/HT 2.2.6 Dual Programmable Timers The processor provides two independent 32-bit timers, with four programmable clock rates. The user configures the timers through the Timer Unit registers. These registers are memory-mapped within the 80960Hx, addressable on 32-bit boundaries. The timers have a single-shot mode and auto-reload capabilities for continuous operation. Each timer has an independent interrupt request to the processor’s interrupt controller. 2.2.7 Processor Self Test W
