Abstract: A system and method for compensating switched mode amplifiers. The amplifier system includes an adaptive filter coupled to the output of circuitry that recovers the analog signal from the output of the switching amplifier circuitry. The adaptive filter derives an inverse transfer function of the forward path through the system. The derived inverse transfer function is used to generate a coefficient map which a compensation filter responsively compensates for from variations in the output load of the amplifier system. In the disclosed method, the deriving the inverse transfer function may further include calibrating the adaptive filter continuously, at system startup or in response to user demand.

Abstract: A method and a circuit of performing an analog to digital conversion in a charge redistribution circuit including a capacitor array of weighted capacitors and a transistor track switch for sampling an input signal into the capacitor array. A common mode voltage is stepped to a voltage sufficient to turn on the transistor track switch during a sampling phase. During the sampling phase, a top plate of each of the capacitors is coupled to the common mode voltage through the track switch while the bottom plate of each of the capacitors is coupled to an input to sample an input signal. During a conversion phase, the top plate of each of the capacitors is decoupled from the common mode voltage and the bottom plates of a selected one of the weighted capacitors is coupled to a first reference voltage, a weight of the selected one of the weighted capacitors proportional to the step in the common mode voltage.

Abstract: A method of operating a cache memory includes the step of storing a set of data in a first space in a cache memory, a set of data associated with a set of tags. A subset of the set of data is stored in a second space in the cache memory, the subset of the set of data associated with a tag of a subset of the set of tags. The tag portion of an address is compared with the subset of data in the second space in the cache memory in that said subset of data is read when the tag portion of the address and the tag associated with the subset of data match. The tag portion of the address is compared with the set of tags associated with the set of data in the first space in cache memory and the set of data in the first space is read when the tag portion of the address matches one of the sets of tags associated with the set of data in the first space and the tag portion of the address and the tag associated with the subset of data in the second space do not match.

Abstract: A computer system includes a register file and an arithmetic logic unit (ALU) for reading data from the register file. The ALU is configured to conduct data processing of the data which was and to store the results of the data processing in the register file. The computer system further includes a condition code stack configured to hold data indicative of the context results of the data processing by the ALU. The ALU is further configured to query the condition code stack for predetermined bit values to determine operations controlled by the ALU. In particular, value of a specified data item in a condition code stack is queried, and the queried value of the data item is used to implement transfer control.

Abstract: Data is transmitted over a computer network from a source network component to one or more destination network components. Thereafter, one or more acknowledgements are transmitted from one of the destination network components to the source network component; and different data, which may include retransmissions, from the previously transmitted data is transmitted from the source network component to the one or more destination network components. A negative acknowledgement message from the destination network component may be transmitted to the source network component upon a failure to receive one or more of the transmitted data packets, the negative acknowledgment including packet identifications of said one or more data packets. Then data packets identified by the identifications received in a negative acknowledgement may be retransmitted before transmitting other packets. The negative acknowledgements thus indicate failed receipt of data. Positive acknowledgements indicate successful receipt of data.
