摘要： Information display systems capable of iconically representing the components of a hybrid powertrain and method thereof. In operation, the information display systems indicate the specific powertrain components in the hybrid system that are active in various hybrid operational modes (e.g., electric launch, blended torque, etc.). In particular, active components are highlighted (i.e., increased intensity) by the display and non-active components are faded (i.e., decreased intensity). In one embodiment, the vehicle wheels are depicted with a static intensity in-between that of the active components and the non-active components. This allows the vehicle operator to clearly see which components are active during each hybrid system mode, and to gain a simplified picture of hybrid system behavior during normal operation at a glance.

摘要： LDPC (Low Density Parity Check) code size adjustment by shortening and puncturing. A variety of LDPC coded signals may be generated from an initial LDPC code using selected shortening and puncturing. Using LDPC code size adjustment approach, a single communication device whose hardware design is capable of processing the original LDPC code is also capable to process the various other LDPC codes constructed from the original LDPC code after undergoing appropriate shortening and puncturing. This provides significant design simplification and reduction in complexity because the same hardware can be implemented to accommodate the various LDPC codes generated from the original LDPC code. Therefore, a multi-LDPC code capable communication device can be implemented that is capable to process several of the generated LDPC codes. This approach allows for great flexibility in the LDPC code design, in that, the original code rate can be maintained after performing the shortening and puncturing.

摘要： It is the object of the present invention to provide asynchronous circuit design tools for those engineers who are versed in standard hardware description languages (HDLs), which is widely used in industry mainly for synchronous circuit design, to design asynchronous circuits with relative ease. To accomplish the object, the asynchronous circuit design tools of the present invention include a translator for transforming a code written in an asynchronous circuit design language, which is based on a standard HDL and includes minimal primitives for describing the communications between asynchronous circuit blocks or processes, into a code written in a standard HDL, which is originally developed for synchronous circuit design. The codes transformed into the standard HDL can be functionally verified by using commercially available simulators, which are originally developed for verifying synchronous circuit design.

摘要： A clock signal regeneration system and method to adjust the phase of a frequency-locked clock signal is provided. The system includes a numerically controlled oscillator, a clock source, and an adder. In one embodiment, additional components are included in the system to ensure that underflow or overflow of the numerically controlled oscillator is prevented. In another embodiment, additional components are included to ensure that output pulses from the numerically controlled oscillator do not occur within a minimum time interval. The method includes deriving a phase adjustment factor, adding the phase adjustment factor to a frequency control word, providing the modified frequency control word to a numerically controlled oscillator and generating a phase shifted, frequency-locked output signal.

摘要： Implementation of LDPC (Low Density Parity Check) decoder by sweeping through sub-matrices. A novel approach is presented by which an LDPC coded signal is decoded processing the columns and rows of the individual sub-matrices of the low density parity check matrix corresponding to the LDPC code. The low density parity check matrix can partitioned into rows and columns according to each of the sub-matrices of it, and each of those sub-matrices also includes corresponding rows and columns. For example, when performing bit node processing, the same columns of at 1 or more sub-matrices can be processed together (e.g., all 1st columns in 1 or more sub-matrices, all 2nd columns in 1 or more sub-matrices, etc.). Analogously, when performing check node processing, the same rows of 1 or more sub-matrices can be processed together (e.g., all 1st rows in 1 or more sub-matrices, all 2nd rows in 1 or more sub-matrices, etc.).

摘要： Sub-matrix-based implementation of LDPC (Low Density Parity Check) decoder. A novel approach is presented by which an LDPC coded signal is decoded by processing 1 sub-matrix at a time. A low density parity check matrix corresponding to the LDPC code includes rows and columns of sub-matrices. For example, when performing bit node processing, 1 or more sub-matrices in a column are processed; when performing check node processing, 1 or more sub-matrices in a row are processed. If desired, when performing bit node processing, the sub-matrices in each column are successively processed together (e.g., all column 1 sub-matrices, all column 2 sub-matrices, etc.). Analogously, when performing check node processing, the sub-matrices in each row can be successively processed together (e.g., all row 1 sub-matrices, all row 2 sub-matrices in row 2, etc.).

摘要： LDPC (Low Density Parity Check) coding and interleaving implemented in multiple-input-multiple-output (MIMO) communication systems. Initially, a novel approach is presented by which a wide variety of irregular LDPC codes may be generated using GRS or RS codes. These irregular LDPC codes can provide better overall performance than regular LDPC codes in terms of providing for lower BER (Bit Error Rate) as a function of SNR (Signal to Noise Ratio). A variety of communication device types are also presented that may employ the error correcting coding using a GRS-based irregular LDPC code, along with appropriately selected interleaving, to provide for even better performance. These communication devices may be implemented to in wireless communication systems including those that comply with the recommendation practices and standards being developed by the IEEE 802.11n Task Group (i.e., the Task Group that is working to develop a standard for 802.11 TGn (High Throughput)).
