摘要： With respect to a particular facility semaphore-based synchronizing is executed among a first station and one or more second stations. For each station a single bivalent semaphore is provided. The first station checks all second station semaphores as having a second state relative to its own semaphore's first state. It then executes a first accessing operation and flips the first state. Otherwise it foregoes the first accessing operation. Any second station checks the first station semaphore as having the second state relative to its own semaphore's second state. It then executes a second accessing operation an d flips the latter state. Otherwise it foregoes the second accessing operation.

摘要： An integrated circuit comprises a scan chain with parallel inputs and outputs coupled to a functional circuit. A scan chain modifying circuit is provided coupled to the scan chain. When testing is authorized the scan chain modifying circuit operates in a mode wherein a normal shift path is provided through the scan chain. When testing is not authorized the scan chain modifying circuit operates to effect spontaneous dynamic changes in the shift path, which dynamically vary the length of the shift path between external terminals of the integrated circuit while shifting takes place. In an embodiment the dynamical variations are controlled by a running key comparison. In other embodiments running key comparison is used to disable transfer through the scan chain or operation of functional circuits.
