摘要： Aspects of an encryption/decryption key generation and distribution may include generating one or more keys for use by one of a plurality of encryption/decryption devices coupled to a serial link within a chip. The generated keys may be transmitted via, for example, a high speed serial link to which one or more of the encryption/decryption devices in the chip may be coupled. The encryption/decryption devices coupled to the serial link may be adapted to examine or identify the transmitted key packets on the serial link and determine whether a particular key packet contains a key that which should be utilized by a particular one of the encryption/decryption devices. Upon identification of a key, the key may subsequently be processed and/or utilized by an integrated encryption/decryption processor associated with the encryption/decryption device to which the encryption key belongs.

摘要： Methods and systems for accessing protected memory are disclosed. Aspects of one method may include enabling access to protected memory on a chip when a user access key for the chip matches a customer specific access key that is pre-programmed and stored in a one-time programmable memory within the chip. The protected memory in the chip may comprise non-volatile memory. Portions of the protected memory may be allocated for access by different users. Accordingly, each user may have a different user access key to access the portion of the protected memory allocated to that user. A user may use offset to objects when sending commands to access the protected memory. The object may indicate memory address and data size. This may allow a level of abstraction where a customer may not need to know specific addresses for the portion of the protected memory being accessed.

摘要： A system and method is provided for generating and using multiple synchronized local program timestamps in a media processing system. The system includes an input processor, one or more local timestamp insertion modules, one or more parsers, and an input buffer. Each local program timestamp module includes a clock reference recovery module, a local program clock synchronized to the system time clock of a program source, and a timestamp generator. The system also includes one or more processing modules such as record modules, transmission modules, and display modules. When a data packet is received by the media processing system, the local timestamp insertion module appends a timestamp to the data packet. The timestamp is based on the synchronized local program clock for the program associated with the data packet. The processing modules utilize the synchronized local timestamps and their associated local program clock in a variety of applications.

摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.
