Abstract: An entropy decoder and method for decoding code words with an indication of associated probability for each code word. The decoder can be operable to receive code words and the indication of associated probability. A branch node block can be in communication with a leaf node block. The branch node block comprising one or more branch node lookup tables and branch node control logic. The branch node control logic operable to process a code word in the input buffer using a selected table from the one or more branch node lookup tables to obtain leaf node information and a bit count of a code word size, the branch control logic further operable to refresh the input buffer to replace the bit count of the code word size and to make the leaf node information and the table selection available to the leaf node block.

Abstract: An asset management system is provided, which includes a hardware module operating as an asset control core. The asset control core generally includes a small hardware core embedded in a target system on chip that establishes a hardware-based point of trust on the silicon die. The asset control core can be used as a root of trust on a consumer device by having features that make it difficult to tamper with. The asset control core is able to generate a unique identifier for one device and participate in the tracking and provisioning of the device through a secure communication channel with an appliance. The appliance generally includes a secure module that caches and distributes provisioning data to one of many agents that connect to the asset control core, e.g. on a manufacturing line or in an after-market programming session.
