摘要： An integrated circuit (IC) includes a power grid having first, through fourth nodes for receiving first supply, first ground, second supply, and second ground voltage signals, respectively, a voltage regulator, a reference voltage calibration circuit, a dual-rail sense circuit, and a voltage monitor circuit. The reference voltage calibration circuit receives the first supply, first ground, second supply, and second ground voltage signals and generates a reference voltage signal based on differences between voltage levels of the first supply and ground voltage signals, and the second supply and ground voltage signals. The voltage regulator regulates the first supply voltage signal based on the reference voltage signal and the second supply voltage signal. The dual-rail sense circuit generates a sense signal based on the second supply and ground voltage signals. The voltage monitor generates a voltage monitor signal based on the sense signal that indicates a state of the IC.

摘要： Hardware processors in an SOC integrated circuit logically swapping memories by remapping memory addresses, including tightly coupled and local memories, to enable a sequence of data-processing algorithms to execute more quickly by different hardware processors without having to copy the data between different memories using a relatively slow data crossbar switch. When a memory stores error-correction code (ECC) address information linking stored ECC data with stored user data, the hardware processor dynamically remaps the ECC address information, as needed.

摘要： A MEMS pressure sensor device is provided that can provide both a linear output with regard to external pressure, and a differential capacitance output so as to improve the signal amplitude level. These benefits are provided through use of a rotating proof mass that generates capacitive output from electrodes configured at both ends of the rotating proof mass. Sensor output can then be generated using a difference between the capacitances generated from the ends of the rotating proof mass. An additional benefit of such a configuration is that the differential capacitance output changes in a more linear fashion with respect to external pressure changes than does a capacitive output from traditional MEMS pressure sensors.

摘要： A test structure includes two capacitor structures, wherein one of the capacitor structures has conductor plates spaced apart by a cavity, and the other capacitor structure does not include a cavity. Methodology entails forming the test structure and a pressure sensor on the same substrate using the same fabrication process techniques. Methodology for estimating the sensitivity of the pressure sensor includes detecting capacitances for each of the two capacitor structures and determining a ratio of the capacitances. A critical dimension of the cavity in one of the capacitor structures is estimated using the ratio, and the sensitivity of the pressure sensor is estimated using the critical dimension.
