ST6x86

The following table lists absolute maximum ratings for the ST6x86 CPU microprocessors. Stresses beyond those listed under Table 3.2 limits may cause permanent damage to the device. These are stress ratings only and do not imply that operation under any conditions other than those listed under "Recommended Operating Conditions" ST6x86 is possible. Exposure to conditions beyond Table 3.2 may (1) reduce device reliability and (2) result in premature failure even when there is no immediately apparent sign of failure. Prolonged exposure to conditions at or near the absolute maximum ratings may also result in reduced useful life and reliability.

The ST6x86™ microprocessor is a superscalar, superpipelined CPU that provides sixth-generation performance for x86 software. Since the ST6x86 CPU is fully compatible with the x86 instruction set, it is capable of executing a wide range of existing operating systems and applications, including Windows 95, DOS, Unix, Windows NT, Novell, OS/2, and Solaris. The ST6x86 CPU achieves top performance levels through the use of two optimized superpipelined integer units and an on-chip floating point unit. The superpipelined architecture reduces timing constraints and allows the ST6x86 CPU to achieve P90+ performance levels and above. In addition, the ST6x86 CPU's integer and floating point units are optimized for maximum instruction throughput by using advanced architectural techniques, including register renaming, out-of-order execution, data forwarding, branch prediction, and speculative execution. These design innovations eliminate many data dependencies and resource conflicts that provide optimum performance for Windows 95 software .
