Patent number: 8867781Abstract: A two level cross-correlation based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a predetermined initial signature.Type: GrantFiled: April 30, 2012Date of Patent: October 21, 2014Inventors: Shien-Tai Pan, Bing Wang, Hoai Le, Yi Li, Victor Kai-Chieh Liang, Maurice Chow, Richard Thai

Publication number: 20080201528Abstract: A memory system is provided. A processor provides a data access address. A memory device includes a predetermined number of ways. The processor selectively configures a selected number less than or equal to the predetermined number of the ways as cache memory belonging to a cacheable region, and configures remaining ways as directly addressable memory belonging to a directly addressable region by memory configuration information. A memory controller determines the data access address corresponding to the cacheable region or the directly addressable region, selects only the way in the directly addressable region corresponding to the data access address when the data access address corresponds to the directly addressable region, and selects only the way(s) belonging to the cacheable region when the data access address corresponds to the cacheable region. A configuration controller monitors the status of the ways and adjusting the memory configuration information according to the status of the ways.Type: ApplicationFiled: April 23, 2008Publication date: August 21, 2008Applicant: MEDIATEK INC.Inventors: Ting-Cheng Hsu, Yen-Yu Lin, Shien-Tai Pan

Patent number: 6766383Abstract: Packet-Based Direct Memory Access. The present invention overcomes the oftentimes hardware consumptive and complex implementation of conventional direct memory access (DMA) that employs descriptors. The descriptors that must are employed by conventional DMA must be set up by software, and the handshaking between the hardware and software is typically very cumbersome. The packet-based DMA performed in accordance with the present invention is operable and adaptable to various types of cell-based DMA modes. A flow control regulator, or flow control state machine, is used to control the packet-based DMA performed in accordance with the present invention. Two different multiplexors (MUXs) are employed, one for each of the transmit and the receive packet-based DMA transfers, to select the various cases of packet-based DMA. The present invention is operable within various modes including asynchronous transfer mode (ATM) cell-based asynchronous digital subscriber loop (ADSL) applications.Type: GrantFiled: September 27, 2000Date of Patent: July 20, 2004Assignee: Conexant Systems, Inc.Inventors: Shien-Tai Pan, Chung-Jue Chen, Mark E.

Patent number: 5553253Abstract: Method and apparatus for predicting the outcome of branch instructions subject to execution in a multiple processor digital computer. Pipelining is a popular technique to accelerate the data processing rate of modern computers, and in particular the RISC architecture class of workstations. Accurate prediction of branch instructions is exceptionally important to the efficient use of pipelines, in that erroneous predictions require both the purge and reload of all affected processor pipelines. According to the present invention, branch prediction is based upon a correlation between a history of successive prior branches and a specified branch instruction. In a preferred practice, a branch prediction table is created. The fields in the table are derived and thereafter updated based upon the correlated combination of outcomes from prior branches and the branch address under consideration.Type: GrantFiled: March 30, 1994Date of Patent: September 3, 1996Assignee: International Business Machines CorporationInventors: Shien-Tai Pan, Kimming So

Patent number: 5535213Abstract: A ring configurator for interconnection of data processing and communication systems uses fully covered rings. The ring configuration mechanism can be used to construct a set of covering rings preserving full connectivity for system interconnect. The mechanism can also be used for establishing the routing table for each interconnected system during the system initialization time. To generate a set of edge-disjoint rings, a rotational mechanism is used. The rings are considered stretching along a horizontal direction with nodes aligned in columns across all the rings. With a proper relabeling of the nodes, nodes appearing in the same column position of each ring can be obtained by a simple rotation of the nodes from the previous column of the rings. Once the rotational position is determined for each column, a set of N-1 edge-disjoint rings can be constructed. To find an extra ring so that when combined with the N-1 rings thus found the ring constraints are satisfied, a node reduction technique is invoked.Type: GrantFiled: December 14, 1994Date of Patent: July 9, 1996Assignee: International Business Machines CorporationInventors: Shien-Tai Pan, Ting Cheng, Christos J.
