Methods, apparatus, systems, and articles of manufacture are disclosed to debug a hardware accelerator such as a neural network accelerator for executing Artificial Intelligence computational workloads. An example apparatus includes a core with a core input and a core output to execute executable code based on a machine-learning model to generate a data output based on a data input, and debug circuitry coupled to the core. The debug circuitry is configured to detect a breakpoint associated with the machine-learning model, compile executable code based on at least one of the machine-learning model or the breakpoint. In response to the triggering of the breakpoint, the debug circuitry is to stop the execution of the executable code and output data such as the data input, data output and the breakpoint for debugging the hardware accelerator.

Systems, apparatus, and methods to debug accelerator hardware

Methods, apparatus, systems and articles of manufacture are disclosed for sparse tensor storage for neural network accelerators. An example apparatus includes sparsity map generating circuitry to generate a sparsity map corresponding to a tensor, the sparsity map to indicate whether a data point of the tensor is zero, static storage controlling circuitry to divide the tensor into one or more storage elements, and a compressor to perform a first compression of the one or more storage elements to generate one or more compressed storage elements, the first compression to remove zero points of the one or more storage elements based on the sparsity map and perform a second compression of the one or more compressed storage elements, the second compression to store the one or more compressed storage elements contiguously in memory.

Methods, apparatus, systems and articles of manufacture are disclosed to perform machine-learning model operations on sparse accelerators. An example apparatus includes first circuitry, second circuitry to generate sparsity data based on an acceleration operation, and third circuitry to instruct one or more data buffers to provide at least one of activation data or weight data based on the sparsity data to the first circuitry, the first circuitry to execute the acceleration operation based on the at least one of the activation data or the weight data.

Methods, apparatus, systems, and articles of manufacture are disclosed that increase data reuse for multiply and accumulate (MAC) operations. An example apparatus includes a MAC circuit to process a first context of a set of a first type of contexts stored in a first buffer and a first context of a set of a second type of contexts stored in a second buffer. The example apparatus also includes control logic circuitry to, in response to determining that there is an additional context of the second type to be processed in the set of the second type of contexts, maintain the first context of the first type in the first buffer. The control logic circuitry is also to, in response to determining that there is an additional context of the first type to be processed in the set of the first type of contexts maintain the first context of the second type in the second buffer and iterate a pointer of the second buffer from a first position to a next position in the second buffer.

Herein is disclosed a slack distribution system comprising one or more sensors, configured to deliver sensor data to one or more processors in a first vehicle; a wireless communication circuit, configured to wirelessly transmit to a second vehicle; one or more processors, configured to determine from at least the sensor data, during first vehicle deceleration, a slack distance between the first vehicle and the second vehicle; and when the slack distance is less than a predetermined threshold, to cause the wireless communication circuit to transmit to the second vehicle a slack request message, wherein the slack request message is a request to change the slack distance.

Vehicle slack distribution

Various systems and methods for implementing an anti-collision mechanism are described herein. A system for a lead vehicle to provide a visible light communication (VLC) message to a trailing vehicle behind the lead vehicle includes a vehicle controller subsystem of the lead vehicle, to: receive from a sensor array interface, sensor data from a forward-facing sensor incorporated into the lead vehicle; determine, using a processor, from the sensor data that a hazard exists; initiate the application of brakes with a braking force; and initiate, via a light controller, a VLC message to the trailing vehicle, the VLC message including the braking force.

Vehicle-to-vehicle communication

Apparatuses, methods and storage media associated with controlling a pedestrian crossing or traffic light are disclosed herein. In embodiments, an apparatus may include a control unit to extend a duration of a pedestrian crossing state of the pedestrian crossing or traffic light in response to receipt of sensor data that convey detection of at least one commence crossing event of the pedestrian, while the pedestrian crossing or traffic light is in a pedestrian crossing state, but yet to receive sensor data that convey detection of all corresponding end of crossing event or events of the one or more pedestrians, prior to expiration of the duration of the pedestrian crossing state. The controller may extend the duration of the pedestrian crossing state until receipt of sensor data that convey receipt of all corresponding end of crossing event/events of the one or more pedestrians, or until a timeout threshold is reached.
