摘要： A technique for content management involves storing runtime state of content externally. A system created according to the technique may include a state server that receives runtime state of content from a playback device, and provides the runtime state to that or another playback device upon request. A playback device constructed according to the technique may include a content state recovery engine for recovering runtime state that was previously stored externally to the playback device. A method according to the technique may include generating the runtime state locally, storing the runtime state externally, and re-acquiring the runtime state.

摘要： Delivery of licenses in a closed distribution system including a playback device and secure processor. The secure processor allows only use of authorized content, and the playback device is authorized to execute content. A user requests a license to selected content using a communication link, without the playback device, outside the closed content system to a license server. The user requests licenses using SMS, sending small amounts of information, possibly including proofs of purchase. The server responds using SMS, providing the user with a code representing information interpretable as a license, such as an encrypted content key or a shared secret known to the user. The user, using a keypad or other device, inputs that code to the playback device, which determines if it authorizes use of the content. The playback device authenticates the license, determining whether that license authorizes the user for the content, and enforces the licensed rights.

摘要： A method and computer program product, within an optimizing compiler, for precise feedback data generation and updating. The method and computer program uses instrumentation and annotation of frequency values to allow feedback data to stay current during the multiple optimizations that the program code undergoes during compilation. Global propagation of known precise feedback values are used to replace approximate and unavailable values, and global verification of feedback data after optimization to detect discrepancies is employed. The method and computer program also provides improved instrumentation to anticipate cloning when code is cloned during ceratin compiler optimizations and handles inlined procedures. The result is compiled executables with improved SPECint benchmarks.

摘要： Improving connectivity in a peer-to-peer (P2P) network involves packet forwarding by infrastructure or peers. A system can achieve full connectivity and a setup for transactions that takes a fraction of a second. The system can include a routing table that is initially configured so that packets to peers are routed via the infrastructure. NAT traversal heuristics can be employed to establish direct connections between peers in parallel with packet forwarding in accordance with the routing table. When a direct connection is ready, the routing table can be updated so that packets are sent P2P. If a direct connection cannot be made, the routing table can be updated so that the packets are sent through a peer intermediary without going through the infrastructure.

摘要： Partial redundancy elimination of a computer program is described that operates using a static single assignment (SSA) representation of a computer program. The SSA representation of the computer program is processed to eliminate partially redundant expressions in the computer program. This processing involves inserting .PHI. functions for expressions where different values of the expressions reach common points in the computer program. A result of each of the .PHI. functions is stored in a hypothetical variable h. The processing also involves a renaming step where SSA versions are assigned to hypothetical variables h in the computer program, a down safety step of determining whether each .PHI. function in the computer program is down safe, and a will be available step of determining whether each expression in the computer program will be available at each .PHI. function following eventual insertion of code into the computer program for purposes of partial redundancy elimination. The processing also includes a finalize step of transforming the SSA representation of the computer program having hypothetical variables h to a SSA graph that includes some insertion information reflecting eventual insertions of code into the computer program for purposes of partial redundancy elimination, and a code motion step of updating the SSA graph based on the insertion information to introduce real temporary variables t for the hypothetical variables h.

摘要： A system and method for an optimizer of a compilation suite for representing aliases and indirect memory operations in static single assignment (SSA) during compilation of a program having one or more basic blocks of source code. The optimizer converts all scalar variables of said program to SSA form, wherein said SSA form includes a plurality of variable versions, zero or more occurrences of a .chi. function, zero or more occurences of a .phi. function, and zero or more occurrences of a .mu. function. The .chi. function, .phi. function, and .mu. function are inserted for the variable versions. The optimizer also determines whether a variable version can be renamed to a zero version, and upon such a determination, the optimizer renames the variable version to a zero version. The optimizer further converts all indirect variables of a program to SSA form, wherein the SSA form includes a plurality of virtual variable versions such that a virtual variable is assigned to an indirect variable, zero or more occurrences of a .chi. function, zero or more occurences of a .phi. function, and zero or more occurrences of a .mu. function. The .chi. function, .phi. function, and .mu. function are inserted for the virtual variables. The optimizer hashes a unique value number and creates a corresponding hash table entry for each variable version and each virtual variable remaining after renaming all zero versions. The optimizer also applies global value numbering to each basic block of the program.
