摘要： An interface is described which has at least one chip side port with a first plurality of pins for conveying fields of a packet and first and second circuit side ports each port having a set of pins with a lower number than the first set of pins in the chip side port. The interface is constructed so that interrupt signals from an off-chip circuit can be conveyed on-chip in a manner such that the interrupt signals are indistinguishable from interrupt signals received from on-chip modules connected to an on-chip communication path. The same principle is applicable to power-down signals.

摘要： A prototype system is described having an integrated circuit including an on-chip processor and an on-chip router connected to off-chip resources via an interface. A request directing unit on the chip receives memory access requests and directs them in accordance with either one of two address maps. In one of the address maps, a first range of addresses is allocated to at least one on-chip resource and a second range of addresses is allocated to the interface. In the other memory address map, the first range of addresses is also allocated to the interface. An integrated circuit including such a request directing unit is also described, together with a method for evaluating a prototype system.

摘要： An integrated circuit is operable to execute boot loader code and a boot code from external memory. To provide security so that the CPU does not execute malicious codes, the circuit resets in a restricted mode in which only certain functional units may be connected. In the restricted mode the CPU is only able to fetch boot code from an external memory for transfer to an internal memory. A hash function operates on the fetched boot code to determine whether it is authentic and, if it is determined that the code is authentic the circuit is reset to an unrestricted mode to continue executing from the boot code now stored in the internal memory. Further security is provided by a watchdog timer function which resets the circuit if the boot code is not determined to be authentic within a threshold period of time.

摘要： An integrated circuit of the type comprises a plurality of units that may act as initiators and targets. At least some of the units are for a first purpose such as a cable modem function and others are for a second purpose such as television data processing. The units are connected together by a interconnect comprising a number of nodes. One of the nodes is configurable such that requests made from initiator units on one side of the node to target units on the other side of the node are not sent to the target units. The units for the first purpose are arranged on the opposite side of the node from those of the second purpose, so that the circuit is effectively configurable into two separate logical partitions, one partition for television data processing and the other partition for cable modem functions.
