Abstract: Apparatuses and methods of shuttering glasses are disclosed. One apparatus includes a first lens operable to blank for a first blocking time, a second lens operable to blank for a second blocking time, and a controller for controllably setting at least one of the first blocking time and the second blocking time.

Abstract: A digital signal processor comprises an instruction analysis unit, a digital signal processor (DSP) core and a memory unit. The instruction analysis unit receives an instruction and determines the required bit width M for the data process corresponding to the instruction. The DSP core performs the M-bit data process based on the bit width M determined by the instruction analysis unit, and the memory unit stores multiple data and performs the M-bit access based on the bit width M determined by the instruction analysis unit thereby allowing the DSP core to access, and at lest one available space in the memory unit will be adjusted such that only the access space having the bit width M for the operation corresponding to the instruction will be open in each access, thereby effectively achieving the effect of power-saving.
