Abstract: Disclosed approaches for limiting use or a programmable IC involve a provider of programmable ICs generating, using one or more private keys of the provider, one or more signed configuration bitstreams from one or more circuit designs received from a customer. The provider changes the general purpose programmable IC into an application programmable IC that can only be programmed by the one or more signed configuration bitstreams. The application programmable IC and the one or more signed configuration bitstreams are provided from the provider to the customer.

For example, the integrated circuit comprises a plurality of circuit components, an internal temperature sensing device deployed among the plurality of circuit components; and a plurality of ring-oscillators deployed among the plurality of circuit components, wherein at least one of the plurality of ring-oscillators is deployed adjacent to the internal temperature sensing device, where the plurality of ring-oscillators is used to provide one or more temperature measurements, e.g., a temperature gradient, for the integrated circuit.

Abstract: Method and apparatus for a dynamically reconfigurable system monitor (20) are described. A system monitor (20) has registers (206) accessible via a reconfiguration port (201). At least one of the registers may be dynamically reconfigured via the reconfiguration port (201) to select a channel to be monitored or to store an alarm value to be used in monitoring by the system monitor (20). Additionally, the system monitor (20) may be embedded in a columnar block architecture.

Abstract: Method and apparatus for digital calibration of an analog-to-digital converter (ADC). One example relates to calibrating an analog-to-digital (A/D) conversion system having an N-bit resolution. The A/D conversion system includes an ADC that generates an output having N most significant bits (MSBs) and M least significant bits (LSBs) (i.e., an N+M bit resolution). An offset calibration circuit is configured to determine an offset in the ADC and to compensate the N+M bit output using the offset to provide an N+M bit offset corrected output. A gain calibration circuit is configured to determine a gain correction factor for the ADC and to compensate the N+M bit offset corrected output using the gain correction factor to provide an N bit offset and gain corrected output.

Abstract: Method and apparatus are described for providing analog capability with boundary-scanning for an integrated circuit. The integrated circuit includes a boundary-scan controller (1517) coupled to an analog-to-digital converter (200). An analog channel is selected for input to the analog-to-digital converter (200). Analog information is converted to digital information by the analog-to-digital converter (200), and then such digital information may be stored in data registers (209) for reading out via the boundary-scan controller (1517).

Abstract: A crossbow has a prod in two parts, each of which is pivotally connected with the stock so that the prod parts can lie alongside the stock when the bow is not in use. When the bow is prepared for use, the prod parts are clamped in operative positions by a mechanism which includes a handle and which provides a substantial mechanical advantage to the operator.
