Systems and a method for controlling power of a device with power management software are described. In one embodiment, a computer implemented method initiates power control having ON-OFF keying to control power consumption of a device for energy efficiency and energy conservation. An ON-OFF period of the ON-OFF keying for the device is computed. The method sets a target frequency, a target supply voltage, and a power gate control for the device based on the ON-OFF keying.

Methods, apparatus, instructions and logic are disclosed providing double rounded combined floating-point multiply and add functionality as scalar or vector SIMD instructions or as fused micro-operations. Embodiments include detecting floating-point (FP) multiplication operations and subsequent FP operations specifying as source operands results of the FP multiplications. The FP multiplications and the subsequent FP operations are encoded as combined FP operations including rounding of the results of FP multiplication followed by the subsequent FP operations. The encoding of said combined FP operations may be stored and executed as part of an executable thread portion using fused-multiply-add hardware that includes overflow detection for the product of FP multipliers, first and second FP adders to add third operand addend mantissas and the products of the FP multipliers with different rounding inputs based on overflow, or no overflow, in the products of the FP multiplier. Final results are selected respectively using overflow detection.

Software controlled transistor body bias. A target frequency is accessed. Using software, transistor body-biasing values are determined for the target frequency in order to enhance a characteristic of a circuit. The bodies of the transistors are biased based on the body-biasing values, wherein the characteristic is enhanced.

An SOI design layout is converted to a bulk design layout. According to a method of converting a first semiconductor design layout based on an Silicon-on-Insulator (SOI) process to a second semiconductor design layout based on a bulk process, an insulator layer of the SOI process beneath active devices in the first semiconductor design layout is removed. A conductive sub-surface structure for routing voltage is added to the first semiconductor design layout. Further, the active devices from the SOI process are converted to the bulk process to form the second semiconductor design layout without requiring a relayout of the first semiconductor design layout on a semiconductor surface. The bulk design layout is utilized to fabricate a semiconductor device having a plurality of active devices.

Software controlled body bias. A target frequency is accessed. Using software, transistor body-biasing values are determined for the target frequency in order to enhance a characteristic of a circuit. The bodies of the transistors are biased based on the body-biasing values, wherein the characteristic is optimized.
