Linking scalar results directly to scalar operation inputs on a bidirectional databus in a computer which superpositions vector and scalar operations |
摘要 |
In a computer which superpositions vector and scalar operations and in which operation results and operands are conducted between buffer registers and functional units on a bidirectional databus system, the result of one or more currently-executing scalar operations can be routed directly to the input of one or more functional units, bypassing the buffer registers and saving computer operational time. A scalar result is routed through a linking apparatus which directly connects a bidirectional databus path on which the scalar result is being conducted to a databus path on which a scalar operand is to be conducted. The routing is conditioned upon identity between the scalar result and operand and upon availability of a databus path to support the scalar operation. If the conditions are not met, the scalar result is conducted to the buffer registers, where it is held until needed or until a databus path is available. |
