Abstract: A conversion unit converts operands from a conventional number system that represents each binary number in the operands as one bit to redundant number system (RNS) operands that represent each binary number as a plurality of bits. An arithmetic logic unit performs an arithmetic operation on the RNS operands in a direction from a most significant bit (MSB) to a least significant bit (LSB). The arithmetic logic unit stops performing the arithmetic operation prior to performing the arithmetic operation on a target binary number indicated by a dynamic precision associated with the RNS operands. In some cases, a power supply provides power to bit slices in the arithmetic logic unit and a clock signal generator provides clock signals to the bit slices. Gate logic is configured to gate the power or the clock signals provided to a subset of the bit slices.

The controller is further configured to provide the determined lagging task to a second processor to be executed by the second processor to accelerate execution of the lagging task.

The one of the metallization layers has conductor traces. The one of the polymer layers has an upper surface that is substantially planar at least where the conductor traces are positioned.

Abstract: Techniques for improving branch target buffer (“BTB”) operation. A compressed BTB is included within a branch prediction unit along with an uncompressed BTB. To support prediction of up to two branch instructions per cycle, the uncompressed BTB includes entries that each store data for up to two branch predictions. The compressed BTB includes entries that store data for only a single branch instruction for situations where storing that single branch instruction in the uncompressed BTB would waste space in that buffer. Space would be wasted in the uncompressed BTB due to the fact that, in order to support two branch lookups per cycle, prediction data for two branches must have certain features in common (such as cache line address) in order to be stored together in a single entry.

Abstract: Various multi-die arrangements and methods of manufacturing the same are disclosed. In one aspect, a method of manufacturing a semiconductor chip device is provided. A redistribution layer (RDL) structure is fabricated with a first side and second side opposite to the first side. An interconnect chip is mounted on the first side of the RDL structure. A first semiconductor chip and a second semiconductor chip are mounted on the second side of the RDL structure after mounting the interconnect chip. The RDL structure and the interconnect chip electrically connect the first semiconductor chip to the second semiconductor chip.

Abstract: A processor applies offset values to read and write pointers to a first-in-first-out buffer (FIFO) for data being transferred between clock domains. The pointer offsets are based on a frequency ratio between the clock domains, and reduce latency while ensuring that data is not read by the receiving clock domain from an entry of the FIFO until after the data has been written to the entry, thereby reducing data transfer errors. The processor resets the pointer offset values in response to a change in clock frequency at one or both of the clock domains, allowing the processor to continue to accurately transfer data in response to clock frequency changes.

Abstract: Techniques for executing an atomic command in a distributed computing network are provided. A core cluster, including a plurality of processing cores that do not natively issue atomic commands to the distributed computing network, is coupled to a translation unit. To issue an atomic command, a core requests a location in the translation unit to write an opcode and operands for the atomic command. The translation unit identifies a location (a “window”) that is not in use by another atomic command and indicates the location to the processing core. The processing core writes the opcode and operands into the window and indicates to the translation unit that the atomic command is ready. The translation generates an atomic command and issues the command to the distributed computing network for execution. After execution, the distributed computing network provides a response to the translation unit, which provides that response to the core.

Abstract: Methods, systems, and devices for near-memory data-dependent gathering and packing of data stored in a memory. A processing device extracts a function, a memory source address, and a memory destination address from a near-memory data-dependent gathering and packing primitive. A signal to perform gathering and packing operations based on the primitive is sent to near-memory processing circuitry of a memory device. The near-memory processing circuitry receives the signal, gathers data from the memory device based on the function and the memory source address, and packs the gathered data into the memory device based on the memory destination address.

The second kernel performs memory operations that are based upon at least a subset of memory operations in the first kernel.

Abstract: Driver and pre-driver circuitry operate in an integrated circuit with two supply voltages. In one form, a reference voltage generation circuit is operable to respond to varying voltage supply conditions in which a driver may be subject to over voltage effects by generating a reference voltage based the first supply voltage when the second supply voltage is not available, and based on the second supply voltage when the first supply voltage is not available. A first drive signal generation circuit drives a pull-up transistor gate based on a data signal, varying the gate voltage between the second supply voltage and the reference voltage. A second drive signal generation circuit drives a pull-down transistor gate with a signal varying between the second supply voltage minus the reference voltage, and zero volts. In one form, certain gate-source voltages in the driver are maintained to be equal.
