    Abstract: The gate of a P-channel pull-up transistor (MP1) connected between an input node (A) and a supply voltage (VDD) in a buffer circuit (21) is coupled to a test node (22). An N-channel pull-down transistor (MNpd) is connected between the input node (A) and ground and has a gate connected to the test node (22). A logic low signal provided to the test node (22) allows the circuit (21) to operate normally. During test mode, a logic high signal is provided to the test node (22) to turn off the P-channel pull-up transistor (MP1) and thus prevent DC current flow in the circuit via the pull-up transistor (MP1). This logic high signal also turns on the pull-down transistor (MNpd) and, by shorting the input node (A) to ground potential, prevents any other DC crossover currents from flowing in the circuit (21).

    Abstract: A switch system and method transfer a data packet from a source data port to one or more destination data ports through a switch. The system comprises a source input buffer, a first and a second source input path, a first and a second output path and at least one crosspoint circuit. The source input buffer includes a first and a second data section. The first and the second data sections are coupled to the first and the second input paths respectively. The first and the second input paths couple through the crosspoint circuits at each intersection with the first and the second output paths. The method includes loading the data packets into data sections of an input buffer, transferring each data packet across an input path dedicated for each data section, transmitting each data packet over its input path, and switching the data from the input path to the output path based on a voltage differential. A crosspoint circuit in the switch system includes a first and a second reduced voltage swing line, a first and a second transistor circuit for each data input path and a sense amplifier for a data port. The first reduced voltage swing line is coupled to the first transistor circuit, the second reduced voltage swing line is coupled to the second transistor circuit and both reduced voltage swing lines are connected to the sense amplifier. The method of the unit comprises the steps of charging a first and a second reduced voltage swing line to a predetermined voltage, discharging the voltage from the first reduced voltage swing line, maintaining the voltage in the second voltage line, receiving a clock signal at the sense amplifier, and generating an output signal based on a voltage differential between the voltage lines.

    Abstract: In a microprocessor, apparatus and method coordinate the fetch and issue of instructions by rotating multiple, fetched instructions into an issue order prior to issuance and dispatching selected of the issue ordered instructions. The rotate and dispatch block including a mixer for mixing newly fetched instructions with previously fetched and unissued instructions in physical memory order, a mix and rotate device for rotating the mixed instructions into issue order, an instruction latch for holding the issue ordered instructions prior to dispatch, and an unrotate device for rotating non-issued instructions from issue order to physical memory order prior to mixing with newly fetched instructions. During the fetch cycle, multiple instructions are simultaneously fetched from storage in physical memory order and rotated into a PC-related issue order within the rotate and dispatch block. During the next clock cycle, selected ones of the previously fetched and rotated instructions enter the issue cycle, a new set of instructions are fetched in physical memory order, the previously fetched and rotated instructions which were not issued are rearranged into physical memory order and mixed in physical memory order with the newly fetched instructions, together all fetched and non-issued instructions are rotated into issue order prior to the next issue cycle, and so forth until all instructions have passed through the pipeline.

    Abstract: A basic unit for obtaining an output is constituted by multiplying a number of inputs by weights, totaling the results of multiplications to obtain a product sum and obtaining the output from this product sum by use of a threshold function. A hierarchical network consisting of an input layer, an intermediate layer and an output layer is constituted by use of such a basic unit. The hierarachical network conducts learning by determining the updating quantity of the weights from errors between the output signals obtained from the output layer for a number of inputs and teacher's signals representing the values which the output signals should take on, in accordance with a back-propagation method in order to obtain the weight value which keeps the sum of error values within a predetermined allowance range. In learning of such a hierarachical network, the updating quantity of the weight to be obtained at the time of the current weight updating cycle is determined in consideration of the updating quantity of the weight obtained at the time of ne cycle earlier updating cycle than the last updating cycle in addition to the updating quantity of the weight determined at the time of the last weight updating cycle.
