Abstract: Configuration devices in a module. In some embodiments a radio-frequency module includes a serial bus including a first serial data line and a second serial data line. The radio-frequency module also includes a control component coupled to the serial bus and the first switch, the control component configured to determine whether first data is detected on the first serial data line, determine whether second data is detected on the second serial data line, and decode a command based on the first data and second data when the first data is detected on the first serial data line and when the second data is detected on the second serial data line.

Abstract: The invention concerns a procedure and a device for emulating a programmable unit using an external emulation device. The method comprises transferring a signal to the external emulation device, which allows deriving the original CPU clock signal of the target programmable unit, and, in a defined relationship with the CPU clock signal (8), emulation data, which are formed by those data, which cannot be calculated on the basis of a given model of the target programmable unit and on the basis of the program code. The target programmable unit is emulated by the external emulation device (1) using the transferred emulation data, and respective trace data are ascertained from the emulation. The invention further concerns an apparatus for emulation, comprising a target programmable unit, which has at least one CPU, and comprising an emulation device, which, as an external unit (14), is connected via an emulation port as a communication link with the target programmable unit.

Abstract: Various technologies and techniques are disclosed for performing configuration debugging comparisons. Snapshots are acquired from at least two computer systems to be compared. The snapshots from the computer systems are then compared. Heuristics are used to determine which differences are actually logically equivalent and thus not to be identified as differences. Comparison results are generated and then displayed in a manner that allows a user to see one or more differences identified between the systems. A filtering feature is provided to allow the user to further filter the comparison results based on a type of issue to be diagnosed. A requirements feedback feature is provided to allow the user to add a user-identified difference as a configuration requirement to a system model.

Abstract: A system and method for testing software code for use on a target processor are disclosed. A system includes a test processor which includes a core substantially similar in physical design and functionality to the target processor for which the software code is intended to be used and an emulation ring including a logic interface to facilitate emulation of the test processor using at least one emulation methodology.
