摘要： A reconfigurable instruction encoding method includes the followings. An instruction distribution of an application is counted, and multiple instruction pairs with higher utilization rates are accordingly found. Multiple instructions of the instruction pairs are duplicately encoded according to multiple reserved sections of an original instruction table, so that the instructions have corresponding reconfigured codes and a reconfigured instruction table extended from the original instruction table and including the reconfigured codes is obtained. A compiler is utilized to generate multiple machine codes according to the reconfigured instruction table and consecutive execution instructions. Hamming distance of the machine codes corresponding to the reconfigured instruction table and the execution instructions are not longer than Hamming distance of the machine codes generated according to the original instruction table and the execution instructions.

摘要： A method for operating a demodulator to demodulate a first channel is provided. The demodulator stores parameters of a second channel that is scanned before the first channel. The method comprises the following steps. First, the demodulator is reset. Second, an orthogonal frequency division multiplexing acquisition is processed to search Transmission Parameter Signaling and mode/guard interval parameters for the first channel and using the parameters of the second channel to process a forward error correction acquisition for the first channel. Third, a determining step is performed to determine whether or not the forward error correction for the first channel is locked and the Transmission Parameter Signaling for the first channel are not locked. Finally, the parameters of the second channel is used to demodulate the first channel when the forward error correction of the first channel is locked and the Transmission Parameter Signaling of the first channel are not locked.

摘要： A hybrid simulation model includes a real model, a bus interface and an acceleration model. The real model simulates a group of instructions. The acceleration model includes a trace generation unit, a trace replay unit, a selection unit, a snapshot generation and load unit and a virtual breakpoint control unit. The trace generation unit records at least one trace file of the real model in a first simulation. The trace replay unit reads and accordingly accesses the at least one trace file. The selection unit dynamically switches to perform a real simulation or a trace simulation. The snapshot generation and load unit generates at least one status snapshot file and loads the at least one status snapshot file to the real model in repeated simulations. The virtual breakpoint control unit controls the selection unit to switch between the trace simulation and the real simulation according to a virtual breakpoint.
