Patent EP-0404445-A2 (EP)
Inventor: DIGHE RAJIV S
IPC: H04L12/56
Filed: 1990-06-14
Abstract: Improved throughput is realized in a packet cross connect switch by including an addressable memory unit in each of a plurality of input ports for storing packets and by allowing each of a plurality of output ports to address directly any one of the input ports to obtain a particular packet stored therein, which is destined for the output port. To this end, the input ports supply the packet destination and starting address of the packet stored in their memory to a scheduler. The scheduler controllably selects an output port assigned to the packet destination and supplies packet output information to the selected output port including the packet starting and the identity of the input port storing the packet. When a particular output port is ready to obtain a particular packet, it addresses the memory unit in the particular input port to read the first packet word. The addressed packet word is supplied via a data bus to the requesting output port. Thereafter, the packet address is incremented by one packet word at a time and the corresponding packet words are read out of the input port memory units until the entire packet has been supplied to the requesting output port.

Abstract: Between counter-propagating lignt beams in a fiber optic gyro are provided phase differences± π/2 rad alternatively at intervals of multiples of the propagation time τ in accordance with a biasing signal. Interference fringes are converted to electric signals corresponding to the intensity thereof. A step value signal for phase negative feedback is derived from a synchronous detector (22) and the step value is accumulated by an accumulator (33). When the accumulated output exceeds a threshold value corresponding to 2Mπ , the accumulator outputs the overflow value, an overflow signal (OVF) and its polarity (OSS). The accumulated output is D/A converted to drive an optical phase modulator (18). A control signal generator (36) outputs SGN(OVF) being one of (-1,0,+1). This output is applied to a multiplier (41). The level difference between the outputs of the synchronous detector before and after the biasing signal is changed over at the kτ time intervals is detected by a conversion error detector (37). The detected output is multiplied by the control signal, and the result is integrated by an integrator (42), the output of which is used to control the conversion gain of the D/A converter by a negative feedback, thereby compensating for a change in the conversion gain of the optical phase modulator.

Abstract: 5 n7 This invention relates to electronic equipment comprising microprocessors, and more specifically microprocessors employed within radio receiver circuits, incorporating on-chip memory (301, 302, 303) and which have the ability to operate in either a single chip or expanded mode. The single chip mode restricts microprocessor (300) operation to internal operation and thereby inhibits external addressing and locally generated noise whereas the expanded mode allows external addressing. A software program, comprised from modules of program code, is categorised into a first and a second category of routines. First category routines are related to equipment functions which are affected by generated noise to a higher degree and, when in operation, are stored in the internal memory (301, 302, 303). Second category routines are stored in a memory external to the microprocessor (201, 202) and are related to equipment functions which are affected by generated noise to a lesser degree. The first and second category routines are executed in the microprocessor's single chip and expanded modes respectively.
