Abstract: A fan module for an aircraft turbomachine includes a fan with a disc carrying fan blades and a rotor of an electric machine. The rotor has an annular shape and is mounted coaxially downstream of the fan. The module further includes an annular support for the rotor with a downstream end fixed to the rotor and with an upstream end fixed to the fan disc. The support is fixed to the disc by shear bolts configured to break when a torque transmitted by the disc to the support exceeds a predetermined threshold.

Abstract: A technique to execute transpose and compute operations may include retrieving a set of machine instructions from an instruction buffer of a data processor. The instruction buffer has multiple entries, and each entry stores one machine instruction. A machine instruction from the set of machine instructions is executed to transpose a submatrix of an input tensor and perform computations on column elements of the submatrix. The machine instruction combines the transpose operation with computational operations into a single machine instruction.

Abstract: An integrated circuit that combines transpose and compute operations may include a transpose circuit coupled to a set of compute channels. Each compute channel may include multiple arithmetic logic unit (ALU) circuits coupled in series. The transpose circuit is operable to receive an input tensor, transpose the input tensor, and output a transposed tensor to the set of compute channels. The set of compute channels is operable to generate outputs in parallel, with each of the outputs being generated from a corresponding vector of the transposed tensor.

Abstract: Techniques to take advantage of the single-instruction-multiple-data (SIMD) capabilities of a processor to process data blocks can include implementing an instruction to fuse the data blocks together. The fuse input instruction can have a first input vector, a second input vector, a select input, a first output vector, and a second output vector. The fuse input instruction selects a portion of the first input vector and a portion of the second input vector based on the select input, sign extends the selected portion of the first input vector and the selected portion of the second input vector, and shuffles data elements of the sign extended portion of the first input vector with data elements of the sign extended portion of the second input vector to generate the first and second output vectors.

Abstract: Systems and methods are provided to perform multiply-accumulate operations of reduced precision numbers in a systolic array. Each row of the systolic array can receive reduced inputs from a respective reducer. The reduced input can include a reduced input data element and/or a reduced weight. The systolic array may lack support for inputs with a first bit-length and the reducers may reduce the bit-length of a given input from the first bit-length to a second shorter bit-length and provide the reduced input to the array. In order to reduce the bit-length, the reducer may reduce the number of trailing bits of the input. Further, the systolic array can receive a reduced and rounded input. The systolic array can propagate the reduced input through the processing elements in the systolic array. Each processing element may include a multiplier and/or an adder to perform arithmetical operations based on the reduced input.

Abstract: To improve utilization of a systolic array, each row of the array is provided with a number of general purpose row input data buses. Each of the general purpose row input data buses can be operable to transfer either feature map (FMAP) input elements or weight values into the processing elements of the corresponding row of the array. By using such general purpose row input data buses, concurrent matrix multiplications as well as faster background weight loading can be achieved in the array.

Abstract: Techniques for compressing a neural network model by mixing compression ratios (sparsity patterns) are described. The weight tensor of a neural network model is divided into weight groups. The pruning cost of compressing the weight values according to a compression ratio is determined for each weight group, and a pruning cost distribution for the compression ratio is generated from the pruning costs of the weight groups. A cost threshold can then be selected from the pruning cost distribution, and weight groups having a pruning cost below the selected cost threshold are compressed according to the compression ratio. The remaining weight groups can be compressed using one or more less aggressive compression ratios. The cost threshold can be adjusted to tune the overall sparsity and accuracy of the compressed neural network.

Abstract: Systems and methods are provided to perform multiply-accumulate operations of reduced precision numbers in a systolic array. Each row of the systolic array can receive reduced inputs from a respective reducer. The reducer can receive a particular input and generate multiple reduced inputs from the input. The reduced inputs can include reduced input data elements and/or a reduced weights.

The systolic array may perform multiply-accumulate operations on each unique combination of the multiple reduced input data elements and the reduced weights to generate multiple partial outputs. The systolic array may sum the partial outputs to generate the output.

Abstract: To take advantage of the architecture of a systolic array tailored to perform sparse matrix multiplications, a weight matrix can be converted into a set of constrained fine-grained sparse weight matrices. The conversion process may include receiving a request to perform a matrix multiplication operation with a weight matrix, and determining that the weight matrix satisfies a sparsity condition to convert the weight matrix into a set of constrained fine-grained sparse weight matrices. The weight matrix can then be converted into a set of constrained fine-grained sparse weight matrices. Computer instructions can then be generated for an integrated circuit device to perform the requested matrix multiplication operation as a set of sparse matrix multiplication operations using the set of constrained fine-grained sparse weight matrices.

Abstract: A retractable pallet fork carriage assembly is provided that enhances the safe operation of a lift vehicle, such as a loader or telehandler. A carriage assembly is coupled to a fork tyne assembly through scissor links that expand and retract the tynes relative to the carriage assembly. When the scissor links are closed, the fork tynes extend through the carriage assembly to receive a payload (e.g., a pallet). When an operator wants to remove the payload, the fork tynes retract while the payload is supported against the carriage assembly. In this way, the load remains in one stationary position while pallet fork tynes are retracted under the payload to release the payload. Various sensors generate and/or send signals to limit the operation of the boom lift, boom, and/or retractable attachment when a distance or load is out of a threshold range.

Abstract: Apparatus and a corresponding method of operating a hub device, and a target device, in a coherent interconnect system are presented. A cache pre-population request of a set of coherency protocol transactions in the system is received from a requesting master device specifying at least one data item and the hub device responds by cause a cache pre-population trigger of the set of coherency protocol transactions specifying the at least one data item to be transmitted to a target device. This trigger can cause the target device to request that the specified at least one data item is retrieved and brought into cache. Since the target device can therefore decide whether to respond to the trigger or not, it does not receive cached data unsolicited, simplifying its configuration, whilst still allowing some data to be pre-cached.

Abstract: A supervisory control and data acquisition (SCADA) system includes an input/output (I/O) management system in communication with a SCADA application and multiple SCADA devices. The I/O management system is configured to receive multiple request messages, and for each of the messages, forward the request message to a device driver associated with the SCADA device, and establish an asynchronous connection for communicating with the SCADA device. The I/O management system then receives request message data associated with the request message from the device driver, and forwards the request message data to the SCADA device through the asynchronous connection. When response message data is received from the SCADA device, the I/O management system forwards the response message data to the device driver for generating a response message. When response message is received from the device driver, the I/O management system forwards the response message to the SCADA application.
