摘要： A bi-directional databusing system is used in a computer that superposes vector and scalar operations. The computer consists of a main memory, a plurality of pipelined functional units, and a buffer for staging scalar and vector data objects between the main memory and the functional units. The busing system supports two-way data transfer during each of a succession of bus transfer cycles in which data is transferred to the buffer during one phase of a cycle, and from the buffer during a second cycle phase. The busing system includes three sets of bi-directional memory databuses, one for transferring scalar data objects between the main memory and buffer unit, and the other two for transferring vector data objects between the main memory and the buffer. The bus system also includes a set of bi-directional function buses, each for transferring scalar and vector data objects between the buffer and the functional units, with the ratio of the number of data objects transferred to the functional units during a transfer cycle to the number of data objects transferred to the buffer during the same cycle corresponding to a predetermined parametric value.
