Conceptual design of a hardwired main storage management unit
Klaus Berkling · The Computer Journal · 1975
This paper is to present the basic concept of a hardwired storage management system. Information about the status of the storage cells is held in two separate bit-planes whose contents are interrogated and updated by a special processor. The system processes requests for the releases of memory space, returning and receiving base addresses, respectively. It operates concurrently to the CPU, thereby relieving the latter of a considerable workload. The hardware of the processor is designed to accommodate a fast string search algorithm that employs ‘don't care’ states for blockwise addressing of the bit-planes.
