Title: Feedforward amplifiers
Inventor: KING NIGEL JONATHAN RICHARD
IPC: H03F1/32
Filed: 1984-11-17
Abstract: A feedforward amplifier has an input (2) connected to a directional coupler (6) which supplies a signal path including, in series, a compensation circuit (10), a main amplification device (8), a delay line (28) and a combiner (26) connected to the circuit output (4). The compensation circuit (10) is controlled by the output of a correlator with one input which receives the delayed circuit input signal and another input connected to the output of a comparator (16) which compares an attenuated portion of the amplified signal with the delayed circuit input signal. The output of the comparator (16) represent a distortion signal which is fed via a further compensation circuit (22) and a further amplifier (24) to the combiner (26) where it cancels out the distortion introduced in the signal path. The compensation circuit (22) is controlled by a correlator (36) which has one input which receives the output of the comparator (16), and another input fed from a comparator (32) which has one input fed from the output of the combiner (26) and another input fed from the circuit input (2) via delay lines (18 and 34) and an amplifier (33) to bring the two inputs to the comparator (32) to approximately the same power level. <IMAGE>

Title: Loading microcode
Inventor: BALDWIN DAVID ROBERT
IPC: G06F9/24
Filed: 1988-03-23
Abstract: A multiprocessor subsystem, wherein each processor is separately microcoded so that the processors can run concurrently and asynchronously. To conserve lines and provide flexibility in specifying the subsystem configuration, a serial loop interface 225 A-E provides data access from a higher-level processor to all of the control stores 470 of the processors. To maximize the net bandwidth of this loop, each separate control store interfaces to it using a bank of serial/ parallel registers 610 which can load the instructions into the control store, or clock the instruction stream incrementally, or simply clock the instruction stream along as fast as possible. Thus, the bandwidth is used efficiently, and only a minimal number of instructions is required to access control storage for a given processor. <IMAGE>
