Disclosed herein are apparatus, method, and computer-readable storage device embodiments for implementing deconvolution via a set of convolutions. An embodiment includes a convolution processor that includes hardware implementing logic to perform at least one algorithm comprising a convolution algorithm. The at least one convolution processor may be further configured to perform operations including performing a first convolution and outputting a first deconvolution segment as a result of the performing the first convolution. The at least one convolution processor may be further configured to perform a second convolution and output a second deconvolution segment as a result of the performing the second convolution. According to some embodiments, the at least one convolution processor may be further configured to perform at least one further convolution to generate at least one further deconvolution segment, until a number of deconvolution segments output by the convolution processor reaches a deconvolution-size-value.

Deconvolution by convolutions

Executing a simulation of a computer platform, the simulation including simulation models. A dynamic quantum is accessed whose current value specifies a maximum number of units of execution a simulation model is allowed to perform without synchronizing with another simulation model. The dynamic quantum may be received from a user. Respective simulation models are invoked for execution with the current value of the dynamic quantum provided to each of the simulation models. The method also comprises modifying the value of the dynamic quantum based on a simulation event.

Dynamically adjusting speed versus accuracy of computer platform simulation

Simulation control techniques include shutting down peer processes and user code modules, storing an image of a simulation as a checkpoint after the peer processes and user code modules are shutdown, and re-starting user code modules and peer processes after storing an image of the simulation. The resulting checkpoint and processes can be used for restoring from a checkpoint or restarting a new simulation environments having peer processes such as debuggers coupled to the simulation.

Simulation control techniques

Providing a unified view of multiple computer system simulations. A simulation process has a simulation thread that executes a plurality of computer system simulations. The simulation process also has a debug support thread that provides a unified view of the simulations. To provide the unified view, the debug support thread has an external interface, an internal interface to each of the simulations, and an interface converter that converts between the external interface and the internal interfaces. Thus, the external interface provides a unified view of the simulations. The external interface allows a single debugging platform to control and observe the simulations.

Method for dynamically adjusting speed versus accuracy of computer platform simulation

Generating transactional level bus simulation instructions from a bus protocol description is disclosed. A bus protocol description is accessed. From the bus protocol description, a finite state machine is generated. Transactional level bus simulation instructions are generated from the finite state machine. Then, the transaction level bus simulation instructions are stored in computer readable medium.
