The combination of MTCMOS and SIMOX results in 60%-faster operation and 80%-lower power consumption, compared to a conventional CMOS/bulk circuit. In order to reduce the power of not only the circuit but also the system, we propose an interface scheme that is compatible with conventional LSIs or transfers signal at high speed and low power. A standard-cell-based MPU was fabricated using 0.25-/spl mu/m MTCMOS/SIMOX.

Based on the instruction stream and output signals of the control units, this approach provides accurate power consumption data without any knowledge of their logic structures. It is a top-down hierarchical method which can handle random logic control units as well as ROM and PLA based control units. The upper-level power estimation analyses the instructions through their formats, and produces an efficient energy model for instruction format transitions. The lower-level estimation is performed for each instruction format by tracing the transitions of output signals. For simple logic control units, predictable internal signals can be used instead of output signals. We have applied this technique into an architectural level power estimator of a real processor. The accuracy of the estimator is demonstrated by comparing the power values it produces against measurements made by a gate level power simulator for the same benchmark set. The results show that our estimation approach for control units can provide more accurate solution than statistical analysis and is more efficient than conventional look-up table based methods.","PeriodicalId":104431,"journal":{"name":"Proceedings Eleventh Annual IEEE International ASIC Conference (Cat.

The model, verified against MEDICI and HSPICE, describes all regions of operation, namely, subthreshold, linear, and saturation while including the effects of 1) carrier velocity saturation, 2) vertical and lateral high field mobility degradation, and 3) threshold voltage roll-off, all prominent characteristics of sub-micron devices. The key contribution of this model is the physical insight into the on/off current trade-off that ensues with voltage scaling and will be vital to future low power design. Utilizing the model for a complete power-delay analysis of CMOS circuit designs, analytical expressions are derived for: 1) propagation delay, 2) short circuit power (P/sub SC/), and 3) static power (P/sub Static/). Results from the total power (P/sub Total/) consumption analysis indicate that P/sub SC/ and P/sub Static/ may constitute over 1/3 of P/sub Total/ in future low power/high performance CMOS GSI.","PeriodicalId":104431,"journal":{"name":"Proceedings Eleventh Annual IEEE International ASIC Conference (Cat.

In a significant shift from the existing scheduling algorithms for multiple voltages, the proposed approach considers, identifies, and exploits the maximal parallelism available in an initial schedule, and applies a modified stochastic evolution mechanism to iteratively improve, or re-schedule, the previously obtained best-schedule to reduce the maximal power consumption of function-units. Based on simulation and evaluation of the proposed approach (using standard benchmarks), it is observed that a power savings of up to 80% is possible when three supply voltage levels, 5 V, 3.3 V, and 2.4 V are considered. In addition to scheduling for low power, the proposed methodology can serve as a vital guiding tool to a designer for studying the efficacy of different design choices before a final design option is selected.","PeriodicalId":104431,"journal":{"name":"Proceedings Eleventh Annual IEEE International ASIC Conference (Cat.
