Abstract: A memory interface circuit is connectable to a DDR-SDRAM which outputs read data in synchronization with a data strobe signal together with the data strobe signal. A clock generator generates internal clock signals and memory clock signals supplied to the DDR-SDRAM. The memory interface circuit determines a delay of arrival of the data strobe signal relative to the corresponding internal clock signal by using a data strobe signal inputted in a read cycle with respect to the DDR-SDRAM, samples the arrived read data, based on a signal obtained by shifting the phase of the arrived data strobe signal, and synchronizes the sampled read data to the corresponding internal clock signal on the basis of the result of determination of the arrival delay.

Abstract: A method for on demand functional verification of a software model of an application specific integrated circuit (ASIC), in a low-level programming language, which separately handles the creation of the model and the debugging of the functional verification tests to be applied to the model in order to create a verification platform. In a transmission mode, an autonomous circuit emulator is created by replacing the model in a low level programming language physically describing the circuit to be validated with a high level description generating response data in accordance with the functional specification of the design as a function of stimuli received. A verification mode includes integration of the software model in low level language of the circuit resulting from the design into a verification platform, and creation of a connection of a previously validated autonomous circuit emulator to the interfaces of the software model.

Abstract: A method of automatically identifying relevant or suspect data during a digital forensic investigation is described. Software accepts as input raw data which are extracted from various digital data sources. The software or digital forensic and data identification application determines to which one or more identification modules the unknown raw data should be delivered to for processing. This determination is based on the type of data in the extracted raw data coming into the application. Suspect or relevant data that are identified includes that data that are identical to or similar to the extracted unknown raw data. If there are suspect data, the application transmits a message or alert to interested parties or stores the findings/report on an a storage device. In this manner, the suspect data are identified automatically, without intervention by a human being.

The semiconductor device includes a switching circuit and a first register. The switching circuit switches between whether a parallel interface with the outside is to be used as a big endian or a little endian. A first register holds control data of the switching circuit. The switching circuit regards the parallel interface as the little endian when first predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register, and regards the parallel interface as the big endian when second predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register.
Abstract: For simplifying the dual-damascene formation steps of a multilevel Cu interconnect, a formation step of an antireflective film below a photoresist film is omitted. Described specifically, an interlayer insulating film is dry etched with a photoresist film formed thereover as a mask, and interconnect trenches are formed by terminating etching at the surface of a stopper film formed in the interlayer insulating film. The stopper film is made of an SiCN film having a low optical reflectance, thereby causing it to serve as an antireflective film when the photoresist film is exposed.
