Title: Command stacking apparatus for use in a  memory controller
Inventor: WEBSTER MARVIN K
IPC: G06F15/177
Filed: 1979-03-27
Granted: 1982-09-28
Abstract: ABSTRACT OF THE DISCLOSURE      This relates to a stacking apparatus for use in a data processing system memory controller.  Instructions or commands requesting access to memory are accepted and temporarily stored in the stack if such memory is unavailable.          Each new instruction or command is stored in the lowest unoccupied level of the stack.  Associated with each stack level is a busy flip-flop which is set when a command or instruction is stored in its associated stack level.  The busy flip-flop is reset when the command or instruction is passed on to its destination memory.  The level busy flip-flops are monitored to detect when the stack is full thus indicating that further requests be inhibited.  By monitoring the highest level in the stack that is occupied, a measure of throughput can be achieved in order to determine whether the stack should be enlarged or made smaller,

Abstract: Abstract of the Disclosure A process for preparing calcined gypsum (stucco) which comprises treating a mass of calcined gypsum by adding, with thorough blending, small portions of water (about 1-10% by weight) to the calcined gypsum, allowing it to heal, and grinding the healed stucco to recapture the rate of strength development and the ultimate strength which are adversely affected by the water addition.  The principal advantage provided by the addition of small portions of water is a reduction in water demand which is retained despite the grinding and optional drying of the healed stucco.  If the treated calcined gypsum is not used shortly after the healing procedure, it should be dried to provide storage stability.  The reduced water demand is particularly useful in gypsum board manufacture.

Abstract: Specification Of Edward M. Petryk, Jr. AN APPARATUS AND METHOD FOR REPLACEMENT OF A PARALLEL, COMPUTER-TO-PERIPHERAL WIRE LINK WITH A SERIAL OPTICAL LINK                        ABSTRACT OF THE DISCLOSURE There is disclosed herein an apparatus and method for communication between units in a data processing or communication system utilizing light conducting fiber instead of parallel electrical conductor cable. The serial optical link permits potentially higher speed transfers and longer link lengths and utilizes potentially simpler, cheaper and safer construction than is possible with a parallel electrically conductive cable link. Because of the inherent electrical characteristics of copper cables, parallel links are limited to transfer rates of approximately 5000 bytes per second and 100 feet maximum length. By taking advantage of the greater bandwidth of optical fibers and utilization of Manchester or Bi-phase L coded serial data transfers and time division multiplexing, higher transfer speeds and longer link lengths may be achieved. Higher data transfer rates may also be achieved utilizing electrically conductive cables, however cables of larger and more expensive construction would be necessary to eliminate some of the inherent speed limiting properties in cheaper cables. With optical cables, the large bandwidth allows the use of relatively cheap components and a reduction in the number of lines needed between the CPU and the peripheral. Further, the larger bandwidths allow a potentially higher data transfer rate with some protocols despite the fact that serial format is used. In the preferred embodiment, a trigger generator senses when transfer of a data packet is desired. At that time, a header generator generates a header for the data packet, and a Manchester encoder latches the parallel data into a shift register with the first 3 bits used to generate the header. The header bits are shifted out of the shift register. A header generator modifies the clock signal to a Manchester encoder producing a non-Manchester data header. After the header is out, the data is encoded in Manchester format. A receiver at the opposite end of the optical link recovers the clock from the manchester encoded data, detects the header, and shifts the data into a shift register where it is transferred out in parallel format.
