碩士 === 國立中山大學 === 資訊工程學系研究所 === 91 === All of the communication, IA, and the cellular phone need the capabilities which can be provided by the ARM microprocessor that has the advantages with high efficient, low power consumption, and low cost. According to the market research that Gartner proposed, ARM occupied the highest with 54% at the market of embedded microprocessor, and 70% of the cellular phones utilize the ARM kernel techniques in the whole world. The success of ARM is determined by the different on the hardware design compared with the general embedded microprocessor. In my thesis, the significant propose is to study the practicability and the essentiality of the hardware characters of the ARM microprocessor applied on different products. We design “automatic register backup/restore system” to replace ARM’s banked registers. This design is capable of reducing the circuit area of the register file by 27.6% and reducing the read delay of register file by 18.4%. We use a simpler method (TAP instruction) to select scan-chain for test mechanism.
