Abstract

In a data processing system, a method for performing a series of operation sequence results and providing such results including the steps of (1) computing the results for each sequence of operations consecutively and (2) reading the results for the proceeding computations during the computation of a current operation result. This method further includes the use of registers for the temporary storage of the sequence results. During the computation of the operation sequence results, other registers are used in performing the sequence operations. The operations store parameters in a progressive fashion. In other words, the initial operations are performed in one set of registers while the final result from the sequence operation is stored in a different register. The result of a previous operation sequence computation is read from a register that is not being used during the computation of the current sequence operation. Also, included is an interlock capability to prevent the storing of sequence in registers that are concurrently being read.
