Vector processor using buffer for preparing vector data

Abstract From the Canadian patent

In a vector processor a decoder generates a load request signal if an instruction stored in an instruction register is a vector load instruction and causes the instruction to be transferred to a stack. A resource manager has a plurality of flags associated respectively with vector registers provided in a calculation circuit and constantly updates the flags in accordance with contents of the associated vector registers. A contention detector is responsive to a vector load instruction being loaded into the stack for generating a proceed-to-transfer signal if no contention is detected between the vector load instruction and a corresponding flag in the resource manager. A buffer is provided in …
