However, such embedded execution units cause a increase of cost, because all consumers doesn't need such units for their applications, and these units are useless for them. This paper shows a new method of interface between microcontroller and high-performance and high-function execution unit, which can realize to easily connect and separate these units corresponding to every applications. And the evaluation by using some multimedia applications also are indicated.}, title = {組み込み用途マイコンに関する高速演算器接続方式}, year = {1996} }
