- 論文の詳細を見る
A 32-bit motor-drive-specific microcontroller chip was newly designed, implemented using a 0.8 μm doublemetal CMOS process, and its feasibility was successfully tested by applying the fabricated microcontroller chip to a real AC induction motor drive system. The microcontroller chip includes a single-precision floating-point unit, peripheral devices for motor drive, and a memory controller as well as the SPARC V7 CPU. The pipeline scheme and the two-step multiplication method were used in the multiplier of floating-point unit for the best area and speed trade-off, using the standard cell library available for the design. The chip size is 12.7 × 12.8mm^2, the number of transistors is around 562,000, and the power consumption is 1.69 W at the supply voltage of 5 V and the clock frequency of 30 MHz. Both a standard cell library and a full-custom layout were used in the implementation.
