摘要： A filter is arranged to selectively block or allow a data access command from an initiator according to whether the initiator is secure or insecure and whether a data source or destination being accessed is privileged or unprivileged. The data access command contains an identification of the initiator from which the data access command originated and an identification of the data source or destination being accessed. The security filter compares the initiator identification and data source or destination identification contained within the data access command with a list of those initiators defined as secure and a list of those data sources or destinations which are defined as unprivileged. The filter then blocks or allows the data access command signal according to a set of rules.

摘要： A method and apparatus are provided for controlling services provided at a first electronic device at a second electronic device. A plurality of electronic devices connected to a network provide services in the form of providing data to the network, or allowing the data to be manipulated. Each service is represented as a manipulable data object created at the device providing the service. Each object contains sufficient information to allow the service the object represents to be controlled. The objects are transmitted over the network and are stored in an object list maintained by a master device. Any compatible device may then retrieve an object from the object list and use the information contained in it to fully control the service.

摘要： The routing of data streams is discussed, and particularly routing one or more incoming streams to one or more output destination ports. The ability to merge incoming streams is discussed so that several low bit rate input packet streams can be merged into a higher bit rate output stream. An assignment data structure identifies for each input stream the or each destination to which it is to be routed, and a packet allocation data structure holds information about the packets and information about the destination of the packets to allow a memory holding the packets to be controlled accordingly.

摘要： An microcomputer is provided including a processor and a debug circuit including a dedicated link which transfers information between the processor and debug circuit to support debugging operations. In one aspect, the processor provides program counter information, which is stored in a memory-mapped register of the debug circuit. The program counter information may be a value of the processor program counter at a writeback stage of a processor pipeline. Also, trace information including message information is transferred in a non-intrusive manner over the dedicated link. In one aspect, the microcomputer is implemented as a single integrated circuit.

摘要： A semiconductor integrated circuit includes a processor for executing application code from a memory and a verifier processor arranged to receive the application code via the same internal bus as the processor. The verifier processor performs a verification function to check that the application code is authentic. The verifier processor runs autonomously and cannot be spoofed as it receives the application code via the same internal bus as the main processor. An additional instruction monitor checks the code instructions from the CPU and also impairs the operation of the circuit unless the address of code requested is in a given range. The code is in the form of a linked list and the range is derived as a linked list table during a first check.
