    Abstract: 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.

    Abstract: A device for locating a DES key value that corresponds to a packet identification (PID) contained at a variable possible location which comprises part only of a 32-bit packet header. A table stored in memory contains for each DES key: (i) a packet header having 32 bits with a PID of either 12, 9 or 8 bits contained at a defined location and with zero values elsewhere, and (ii) a mask value also having 32 bits with ones contained at the said defined location of the PID and zeros elsewhere. The table is divided into regions for respective packet format types. An incoming packet header at an input is combined with a first one of the mask values from the table to provide a combined value that consists of the value held in the input packet header at the defined location and zeros elsewhere. This combined value is compared with the corresponding packet header stored in the table. When they are not equal, the combining and comparison is repeated for the next row of the table. When they are equal, the corresponding DES key value is read from the table and provided as an output. The system can cope with variable PID formats within the packet header without alteration to the hardware but merely with re-programming of the table contents.

    Abstract: A semiconductor integrated circuit for processing a plurality of received broadcast signals, such as GPS signals, is operable in two modes: acquisition and tracking. In an acquisition mode, a memory arrangement comprising two circulating shift registers circulates samples of a received signal for correlation with a locally generated version of a GPS code. In a tracking mode, the sampled signal is provided direct to the correlators. The same correlators are thereby used to increase acquisition speed.

    Abstract: There is disclosed a circuit and method for demultiplexing in a receiver a digital data stream including at least two types of data, so as to retain only those parts of the digital data stream required by the receiver. In one particular application, such a receiver is used in a television system having a digital set-top-box receiver. A first control circuit extracts a packet identifier from an input data packet in the digital data stream, and generates a signal in dependence on whether the input data packet is of the first or second type. Sets of information associated with the first types of data packets and required by the receiver are stored in a memory under the control of a second control circuit. A third control circuit, responsive to receipt of the first type of input data packet, determines whether at least part of the input data packet matches the stored sets of information, and sets a match signal responsive thereto.
