A data cryptographic device may include a pre-tweak generator to generate pre-tweak values, a pre-tweak value cache memory to store one or more pre-tweak values generated by the pre-tweak generator, and a pre-tweak value selector to check whether a pre-tweak value for an input memory address is stored in the pre-tweak value cache memory. The data cryptographic device may further include a tweak generator to generate a tweak value based on the selected pre-tweak value, and a block cipher to perform at least one block cipher algorithm to at least one of encrypt data, encrypt and authenticate data, decrypt encrypted data, decrypt and verify encrypted and authenticated data, using a cryptographic key and the generated tweak value.

Embodiments related to configurable Media Access Controllers (MACs) are described and depicted.

Configurable media access controller

A system is disclosed that may include an access point and a first wireless basic service set providing data transfer and a second wireless basic service set providing data transfer. The first and second wireless basic service sets are serviced by the access point concurrently and independent from the respective other wireless basic service set, wherein the access point may include a first MAC entity to process first data and a second MAC entity to process second data and wherein the first basic service set is configured to support a mix of contemporary wireless standards and legacy wireless standards and the second basic service set is configured to support only contemporary wireless standards and to operate at a greater data throughput than the first basic service set.

The processing of tasks in a mobile communication terminal that contains two or more microprocessors is disclosed. The processing rate of tasks is increased by redistribution of the tasks between the microprocessors as a function of the operating mode. Particularly in situations in which no conversation and/or no other type of payload signal transmission is taking place, tasks may be redistributed from the application processor to the modem processor and/or to the DSP, so that applications such as compression and/or decompression of video data can be processed more quickly.

Distribution of tasks as a function of the operating mode in mobile communication terminals having two or more microprocessors

An integrated circuit with multiple circuit cores each of which have integrated emulated circuits, and an emulation interface module, such that the integrated circuit has an on-chip debugging system. As cores other than a processor core have integrated emulation circuits, debugging of programs and operations of systems-on-a-chip becomes viable.
