| Number | Title | Issue Date |
| 5386562 | Circular scheduling method and apparatus for executing computer programs by moving independent instructions out of a loop A procedure which is a particular type of software pipelining is provided which increases the efficiency with which code is executed by reducing or eliminating stalls such as by filling delay slots. The process includes moving instructions in a loop from ... | 01/31/1995 |
| 5301153 | Redundant element substitution apparatus A redundant array element or signal line is selectively added and an defective array element or signal line is eliminated by the method and apparatus of the present invention. A multiplexor receives an input signal and a neighboring input signal and outpu... | 04/05/1994 |
| 5285116 | Low-noise high-speed output buffer and method for controlling same A low-noise high-speed output buffer receives digital control signals for varying the switching delay and di/dt of the buffer. For a plurality of output buffers, one buffer is used to determine the digital control signal values for the rest. The switching... | 02/08/1994 |
| 5179670 | Slot determination mechanism using pulse counting A slot determination mechanism wherein a number of bus units establish their positions along the bus and the total number of units on the bus. The units are connected in a bidirectional daisy chain. A one-cycle reset pulse is sent downstream to unit 1 (th... | 01/12/1993 |
| 5101117 | Variable delay line phase-locked loop circuit synchronization system A system for synchronizing the operation of a CPU and coprocessor operating from a common clock signal includes a first voltage controlled delay line connected to receive the clock signal and delay it by a fixed time interval before supplying it to one of... | 03/31/1992 |
| 5056110 | Differential bus with specified default value A solution to the problem in differential buses that the bus state for a given line pair is undefined when no unit is driving either of the bus lines in the pair. The lines in the bus pair are terminated to different voltage levels, thereby establishing a... | 10/08/1991 |
| 4879676 | Method and apparatus for precise floating point exceptions In data processing systems of the type operable to perform floating point computations there is provided a method, and apparatus implementing that method, for predicting, in advance of the floating point computation, whether or not the computation will pr... | 11/07/1989 |
| 4805098 | Write buffer Apparatus is disclosed for buffering writes from a CPU to main memory, in which sequential write requests to the same address are gathered and combined into a single write request. The embodiment described does not permit gathering with the write request ... | 02/14/1989 |
