The CAS device may also be operable to receive unencrypted streaming media content, encrypt the streaming media content utilizing a CAS module, and transmit the encrypted streaming media content. In another embodiment, the CAS device receives streaming media content encrypted utilizing a first CAS, decrypts the received streaming media content utilizing a first CAS module, transmits the unencrypted streaming media content from the first CAS module to a second CAS module, encrypts the unencrypted streaming media content utilizing the second CAS module, and transmits the encrypted streaming media content to a rendering device.

Abstract: One embodiment of the present invention provides a system that facilitates efficient transactional execution. The system starts by executing a transaction for a thread, wherein executing the transaction involves placing load-marks on cache lines which are loaded during the transaction and placing store-marks on cache lines which are stored to during the transaction. Upon completing the transaction, the system releases the load-marks and the store-marks from the cache lines which were load-marked and store-marked during the transaction. Note that during the transaction, the load-marks and store-marks prevent interfering accesses from other threads to the cache lines.

Abstract: Systems and methods for identification of dependent instructions on speculative load operations in a processor. A processor allocates entries of a unified pick queue for decoded and renamed instructions. Each entry of a corresponding dependency matrix is configured to store a dependency bit for each other instruction in the pick queue. The processor speculates that loads will hit in the data cache, hit in the TLB and not have a read after write (RAW) hazard. For each unresolved load, the pick queue tracks dependent instructions via dependency vectors based upon the dependency matrix. If a load speculation is found to be incorrect, dependent instructions in the pick queue are reset to allow for subsequent picking, and dependent instructions in flight are canceled. On completion of a load miss, dependent operations are re-issued. On resolution of a TLB miss or RAW hazard, the original load is replayed and dependent operations are issued again from the pick queue.

Abstract: A computer processor pipeline has both an architectural register file and a working register file. The lifetime of an entry in the working register file is determined by a predetermined number of instructions passing through a specified stage in the pipeline after the location in the working register file is allocated for an instruction. The size of the working register file is selected based upon performance characteristics. A working register file creditor indicator is coupled to the front end pipeline portion and to the back end pipeline portion. The working register file credit indicator is monitored to prevent a working register file overflow. When the a location in the architectural register file is read early, the location is monitored to determine whether the location is written to prior to issuance of the instruction associated with the early read.

Abstract: Methods and apparatus provide for a busy resource encoder to allow for a finer control of spin versus yield decisions. Specifically, the busy resource encoder allows for the execution a first thread, where the first thread is using a particular resource. Additionally, the busy resource encoder allows for the execution of a second thread, where the second thread requires use of the resource which is locked due to first thread execution. The busy resource encoder creates a busy code to indicate the progress of the execution of the first thread in relation to use of the resource by the first thread. The second thread can then read the busy code to determine to execute one of a spin and a yield routine by the second thread.

Abstract: A processing thread obtains an initial status of a reference field associated with an object having data stored in memory. The reference field represents, at least in part, a status of current modification operations (e.g., a status of moving the object from one location in memory to another), if any, applied to the object. The processing thread applies a sequence of instructions to data retrieved from the object to produce computational results for storage in the object. Prior to storing the computational results in the object, the processing thread can confirm whether the reference field has changed since obtaining the initial status.
