Abstract
A data transmission circuit for a digital signal processor chip having a plurality of function blocks, a plurality of global buses which may be selectively connected to each other, and a plurality of local buses which may be selectively connected to an associated global bus and an associated function block. The circuit includes a plurality of first switches for selectively connecting the plurality of local buses to both the plurality of function blocks and the plurality of global buses, and a plurality of second switches means for selectively connecting the plurality of global buses. In a data transmission method for a digital signal processor chip, only those local buses and global buses necessary for data transmission are connected when data is transmitted between the plurality of function blocks. Therefore, movement of data through buses irrelevant to the desired operation is eliminated, and electrical consumption is reduced.
