摘要:
An integrated circuit (IC) bus architecture is disclosed. The bus architecture includes a receiver for fast on-chip signal transmission. The receiver includes a first gate device having one terminal connected to a voltage source and a gate terminal connectable to receive a sense signal. A second gate device includes one terminal connected to another terminal of the first gate device, a gate terminal connectable to receive the sense signal and another terminal serving as an input terminal of the receiver and connectable to an interconnect bus to receive input signals from other components on the IC chip. The receiver also includes a third gate device having one terminal connected to a voltage source and another terminal serving as an output terminal of the receiver and connected to the other terminal of the first gate device. The receiver further includes an inverter having an input terminal connected to the output of the receiver and having an output terminal connected to a gate terminal of the third gate device. The input of the receiver is capable of being pre-discharged to a low signal and the output of the receiver is capable of being pre-charged to a high signal for substantially instantaneous transmission of input signals received by the receiver.

A high performance interconnect that utilizes dynamic driver technology is capable of reduced power operation during periods of low data switching activity. Circuitry is provided that limits the performance of an evaluation operation in the dynamic driver circuitry to clock cycles during which a present input bit of the interconnect differs from a previous input bit. Thus, the evaluation operation and subsequent precharge of the driver output is performed sparingly during periods of low data switching activity. An output circuit is also provided for decoding the data stream flowing through the interconnect at the receiver end thereof. Using the principles of the present invention, it is possible to achieve the performance advantages of dynamic drivers with the switching activity of interconnects that use static CMOS technology.

A dual-rail static logic gate with a self cut-off mechanism is disclosed. In an embodiment, the output of the first rail is coupled to the input of the pull-up device of the second rail and vice versa. The cross-coupling allows the self cut-off mechanism of the static gate to function properly and provides for components which have lower capacitance than conventional static gates. The lower capacitance results in a faster static gate.

A dynamic circuit with a conditional keeper for burn-in. In the described embodiments, a conditional keeper is provided which is active only during the burn-in test, where the conditional keeper is sized larger than the standard keepers so as to compensate for additional leakage currents in the dynamic circuit.

In one embodiment, a processor includes a multiply-accumulate (MAC) unit having a first path to handle execution of an instruction if a difference between at least a portion of first and second operands and a third operand is less than a threshold value, and a second path to handle the instruction execution if the difference is greater than the threshold value. Based on the difference, at least part of the third operand is to be provided to a multiplier of the MAC unit or to a compressor of the second path. Other embodiments are described and claimed.
摘要:
A method includes: delaying an excursion of at least one signal a first number of clock phases when the excursion departs from a value in a first direction; and delaying the excursion of the at least one signal a second number of the clock phases when the excursion departs toward the value in a second direction. The first number of clock phases is different from the second number of clock phases. The at least one signal effects a plurality of succeeding excursions in substantial synchrony with a clocked signal presenting succeeding clock cycles having a plurality of the clock phases in each respective clock cycle.
