Abstract(in English) | This paper presents a high speed 64-bit floating-point (FP) multiplier with a useful function for computer graphics (CG). The critical path delay was minimized by selecting high speed gates and limiting the stage number of series transmission gates (TGs). We implemented the special function of "CG multiplication" that directly multiplies a pixel data by a FP data. The process technology is 0.5-μm CMOS with triple metal. The active area size is 4.2×5.1mm^2. The operating frequency is 286MHz at the supply voltage of 3.3V. Implementation of CG multiplication increases the transistor count only 4%. Also, it has no effect on the delay in the critical path. |
