    Abstract: 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.

    Abstract: A memory stores data in an encrypted form. A modifiable register stores a memory address, a0, defining a boundary separating the memory into two regions. The lower region stores data encrypted using a key B, and the upper region stores data encrypted using a different key A. Data stored on the boundary address is encrypted using key A. Accordingly, when data is read from a memory address a, key A is used to decrypt the data if a≧a0, and key B is used if a

    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: The image sensor includes an array of pixels. Each pixel has a pinned photodiode which transfers charge via a transfer gate to a floating diffusion, from which output is provided by a source follower. Each column has a voltage supply line and a signal line. Each row has a transfer gate control line, a read/reset control line, and a read/reset voltage line which receives alternately zero volts and a predetermined positive voltage from a decoder circuit.

    Abstract: A monolithic semiconductor integrated circuit is provided for selectively encrypting or decrypting data transmitted between one of a plurality of devices on the circuit and an external memory. Two series of data pathways connect the devices and the external memory. The first series of data pathways passes through a cryptographic circuit causing data to be encrypted or decrypted, and the other series of data pathways provides an unhindered route. When a data access request is made by a device, the data is selectively routed along one of the two series of data pathways according to the identification of the device making the data access request. In one example, if data is transmitted from a device to the external memory, the data is selectively encrypted before being stored in the external memory if the device transmitting the data is identified as secure. Then, when that data is retrieved from the external memory by a second device, the data is selectively decrypted only if the second device is identified as secure.

    Abstract: A pinned-photodiode image sensor using shared output amplifiers, for example output amplifiers in the 2.5T arrangement has transfer gate control lines alternating or cross-coupled between successive columns or adjacent rows. This assists in removing row-row mismatches. In preferred embodiments, the approach is applied to Bayer pattern RGB sensors, and allows the gain and/or the exposure of green pixels to be controlled separately from those of red and blue pixels.
