Abstract: Disclosed is an improved approach to implement timing signoff and optimization. Integrated MMMC timing closure functionality is provided in a single software session. The system provides the capability to perform signoff analysis, debugging, ECO, and TSO optimization for a large number of MMMC views in single software session.

Abstract: A technique for incorporating power information in a register transfer level design involves defining a module representing an integrated circuit block having its own power grid. The integrated circuit block, when in a power off mode effectuated by a deactivation of a clock signal to the integrated circuit, uses a device dependent on a power grid of an adjoining integrated circuit block to preserve output information from the integrated circuit block to the adjoining integrated circuit block.

Abstract: A system and method are provided for processing audio and speech signals using a pitch and voicing dependent spectral estimation algorithm (voicing algorithm) to accurately represent voiced speech, unvoiced speech, and mixed speech in the presence of background noise, and background noise with a single model. The present invention also modifies the synthesis model based on an estimate of the current input signal to improve the perceptual quality of the speech and background noise under a variety of input conditions. The present invention also improves the voicing dependent spectral estimation algorithm robustness by introducing the use of a Multi-Layer Neural Network in the estimation process. The voicing dependent spectral estimation algorithm provides an accurate and robust estimate of the voicing probability under a variety of background noise conditions. This is essential to providing high quality intelligible speech in the presence of background noise.

Abstract: A microprocessor is equipped with an address translation mechanism for performing dynamic address translation from a virtual address to a physical address on a page-by-page basis. The microprocessor includes a large-capacity low-associativity address translation buffer, and is capable of avoiding limitations imposed on a TLB entry lock function, while reducing the overhead for address translation. The address translation mechanism comprises an address translation buffer having an entry lock function, and control logic for controlling the operation of the address translation buffer. The address translation buffer includes a lower-level buffer organized as a lower-level hierarchy of the address translation buffer and having no entry lock function, and a higher-level buffer organized as a higher-level hierarchy of the address translation buffer and having an entry lock function, the higher-level buffer having higher associativity than the associativity of the lower-level buffer.
