A method of a fast system call is provided. First, a logical operation to compute a kernel service routine is used. Then the logical operation result is compared with ciphertext from a key register. At least one input for the logical operation is from the relevant information of the required kernel service routine. For example, the start address of the kernel service routine or the content of the start address of the kernel service routine, or combinations thereof. If the logical operation result equals to the ciphertext of the key register, a switch from a user mode to a kernel mode to read the kernel service routine is allowed. Otherwise, the central processing system executes a corresponding exceptional handler routine. Then the operating system terminates the mode switch request and reports an error to the operating system.

The present invention provides a method for fabrication of polycrystalline silicon thin film transistors, which forms a silicon spacer on the sidewall of the active layer of a thin film transistor (TFT) by way of anisotropic plasma etching in a single direction. The silicon spacer provides a mechanism for laser recrystallization on the sidewall to prevent the active layer from shrinkage or shelling-off after the laser recrystallization. According to the present invention, large grains can be formed in the channel without additional mask during production. By doing so, the characteristics of the components are enhanced; the uniformity is improved; and, the production cost is lowered. Therefore, this technique will play an important role in the fields of low temperature polycrystalline silicon thin film transistor (LTPS-TFT).

Disclosed is “System and Method for Digital Content Rights Management on Portable Storage Devices.” Due to the fact that digital content will some become the master industry in the future, a new usage rights management is needed, especially for those storage media such as portable PDA or handy flash. In conventional methods, the network has to be kept alive for determining the license validation. Conversely, the new method only needs to connect to Internet when downloading the digital content that was chosen. The digital content with personal identification and usage rights are encrypted. Henceforth, the digital content is prevented from illegal usage such as copy and unauthorized read. By the usage rights management, several kinds of limitations are defined for being operated in combination with each other, to generate various usage permissions while the overall system is easily managed. This invention is platform independent and suitable for different kinds of portable storage devices.

A multiple skip structure of a pattern matcher uses a shift engine to read a string and divide the string into a front module and a rear module. The shift engine uses the rear module of the string to index the shift index column of a shift table and retrieves a corresponding shift value and signature value back to the shift engine. The shift engine uses the shift value for the first level of filtering. If the shift value indicates a pattern is contained, it then compares a signature value with a shift hash value for a second level of filtering. The shift hash value is obtained from using the front module of the string via a hash function. If the shift hash value equals to the signature value, then it transmits the position of the string to a trie engine for a full pattern matching.

An arithmetic and logic device as an integral part of a processing unit is provided to achieve code size and overhead reduction. The arithmetic and logic device contains several auxiliary computing units, each of which is capable of simple arithmetic and logical operation, under the control of a control unit. By configuring the auxiliary computing units along the data path, additional processing to the operands could be carried out within the same instruction cycle. As such, a processing unit incorporating such an arithmetic and logic device is able to achieve significant performance improvement both in terms of code size and memory access overhead.

A method for fabricating polycrystalline silicon film transistors, which includes a polysilicon spacer capping onto a sidewall of an active layer in the thin film transistors by an isotropic dry etching of the silicon film. This method suppresses the shrinkage of the active layer during recrystallization by the laser. Large grains are formed in the channel after recrystallization utilizing a high-energy continuous wavelength laser or an excimer laser annealing the active layer. This process does not require an additional mask. Uniform arrangement of grain boundaries and large grain sizes promotes uniformity of performance of the device, which is important in the fields of low temperature polycrystalline silicon thin film transistors (LTPS-TFTs).

A non-intrusive debugging framework for parallel software based on a super multi-core framework is composed of a plurality of core clusters. Each of the core clusters includes a plurality of core processors and a debug node. Each of the core processors includes a DCP. The DCPs and the debug node are interconnected via at least one channel to constitute a communication network inside each of the core clusters. The core clusters are interconnected via a ring network. In this way, the memory inside each of the debug nodes constitutes a non-uniform debug memory space for debugging without affecting execution of the parallel program, such that it is applicable to current diversified dynamic debugging methods under the super multi-core system.
