Abstract: The invention deals with a wireless extension of the IEEE 1394 bus. Considered is a scenario where two clusters of 1394 devices are linked to each other by means of a wireless bridge (9). The devices of one cluster shall communicate with devices of the other cluster without being bridge-aware. The wireless bridge, however, provides for a bus reset isolation. This causes a problem each time a bus reset occurs in one of the clusters. To solve this problem it is proposed to implement a buffer memory (22) for self-identification packets in the 1394 interfaces (11) of both boxes of said wireless bridge (9). In particular these buffer memories (22) shall be implemented in the physical layer section (21) of the 1394 interfaces (11). With these buffer memories the self-identification packets of the bus stations in the other cluster can be collected and they can easily be read out during the self-configuration phase of the network after a bus reset when the bus grant is assigned to the box of the wireless bridge that is also connected to the bus where the bus reset has occurred. The physical layer section of the 1394 interface transmits artificial self-identification packets for all bus stations of the other cluster so that data communication can continue without long delays. <IMAGE>

Abstract: An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus, the error correction capability in a burst cutting area of an optical disc can be improved.

Abstract: <P>PROBLEM TO BE SOLVED: To increase the assignment proportion of a regeneration braking force to a target braking force in response to a braking operation force when the braking operation force is in a low region, and at the same time, to reduce the effect delayed feeling of the brake at the time of a sudden braking.  <P>SOLUTION: When the braking operation force is in the low region, the boosting ratio of a booster becomes lower, and the assignment ratio of the regeneration braking force to the target braking force which is set to correspond to the braking operation force becomes higher, and an energy efficiency is increased. When the braking operation force exceeds the low region, the boosting ratio of the booster becomes higher, and an increasing ratio of a fundamental hydraulic pressure which is fed to a wheel cylinder from a master cylinder becomes larger. Therefore, even if a small delay occurs in the feeding of a control hydraulic pressure from the control hydraulic pressure braking force generating device at the time of a sudden braking, the braking means can generate a sufficiently large fundamental hydraulic pressure braking force on wheels.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: The high-performance, RISC core based microprocessor architecture permits concurrent execution of instructions obtained from memory through an instruction prefetch unit having multiple prefetch paths allowing for the main program instruction stream, a target conditional branch instruction stream and a procedural instruction stream. The target conditional branch prefetch path allows both possible instruction streams for a conditional branch instruction to be prefetched. The procedural instruction prefetch path allows a supplementary instruction stream to be accessed without clearing the main or target prefetch buffers. <??>Each instruction set includes a plurality of fixed length instructions. An instruction FIFO is provided for buffering instruction sets in a plurality of instruction set buffers including a first buffer and a second buffer. <??>An instruction execution unit including a register file and a plurality of functional units is provided with an instruction control unit capable of examining the instruction sets within the first and second buffers and scheduling any of the instructions for execution by available functional units. Multiple data paths between the functional units and the register file allow multiple independent accesses to the register file by the functional units as necessary for the execution of the respective instructions. <??>The register file includes an additional set of temporary data registers. These temporary data registers are utilized by the instruction execution control unit to receive data processed by the functional units by the out-of-order execution of instructions in advance of the completed execution of a conditional branch instruction or any instruction that requires additional functional unit processing cycles to complete. The data stored in the temporary data registers is selectively held, cleared or retired to the register file depending on the actual state of the instruction stream at the point where all prior instructions have been executed. <IMAGE>

Abstract: Contemporary computer architectures support pipelining and instruction-level parallelism, in which an operation related to updating array T 1  is followed by an operation related to updating array T 2 . To further improve performance, it is desirable to update arrays T 1  and T 2  together within the loop over i, using one instruction per pair of updates.  The computer architecture employs SIMD instructions (and in our particular example, SSE2 instructions) to update simultaneously the arrays T 1  and T 2  used in Montgomery multiplication, montmul (A,B).  This process involves, in part, processing digits of A in a right-to-left manner and interleaving results of the multiplications involving B (i.e., mul 1 *B[i]) and modulus N (i.e., mul 2 *N[i]) that are used to update arrays T 1  and T 2 .
