摘要： An inappropriate-access module is incorporated in a computer system along with other computer system modules. The inappropriate-access module is connected to a read address decoder and controlling logic located within various other modules. The inappropriate-access module detects inappropriate read accesses or the occurrence of the inappropriate access during operations performed on related sensitive system resources in accompanying computer system modules. The inappropriate-access module produces an inappropriate-access flag, made available to the rest of the system, which invokes responses in the accompanying modules such as a halt in processing and protective measures for system resources. Additionally, a related logic block is able to detect the inappropriate access and produce an inappropriate-access trigger which causes a halt to processing within the logic block as well as in related system modules.

摘要： The disclosed quadrature decoder filtering circuitry for motor control uses one quadrature signal to correct an error in the other quadrature signal, thus allowing a noisy signal due to large dust particles or scratches to be recovered. In some implementations, a system processing for quadrature signals comprises a first circuitry triggered by edges of a first quadrature signal to detect inactivity of a second quadrature signal during consecutive edges of the first quadrature signal. A second circuitry is operable to count the number of consecutive edges of the first quadrature signal during inactivity of the second quadrature signal. A third circuitry is operable to combine transitions of the first quadrature signal with the second quadrature signal during a period of time determined by the count value of the second circuitry.

摘要： A multi-matrix bus system is disclosed that provides proactive quality of service (QoS) by propagating, as soon as possible through an arbitration node in a network transfer request path, a highest priority value coming from an upstream arbitration node or master that has a current bus request pending at the arbitration node. The bus system ensures that any last downstream arbitration node knows at any time which is the highest priority request pending in the network transfer request path from the masters that are competing to share the bus layer switches and arbitration nodes in the network transfer request path.
