Abstract: Methods and systems for register mapping in emulation of a target system on a host system are disclosed. Statistics for use of a set of registers of a target system processor are determined. Based on the statistics a first subset of the target system registers, including one or more most commonly used registers is determined. The registers in the first subset are directly mapped to a first group of registers of a host system processor. A second subset of the set of target system registers is dynamically mapped to a second group of registers of the host system processor.

Abstract: Simulation of the operation of a data processing apparatus having a number of master logic units and slave logic units coupled via a bus is provided. The data processing apparatus performs data transfers between the master logic units and the slave logic units over the bus. Anticipated timing information for each successive data transfer over the bus is generated by assuming that each successive data transfer can occur with exclusive access to the bus, determining whether the anticipated timing information indicates that two or more concurrent data transfers would occur on the bus, and in the event that the anticipated timing information indicates that two or more concurrent data transfers would occur on the bus, generating revised timing information for those data transfers, the revised timing information being generated using bus status information until those data transfers have been completed.

Abstract: In a computerized method for adherence to physical restrictions in the construction of an ITE hearing aid, each component to be placed in the shell of the hearing aid has a collision plot associated therewith. The collision plot is generated as a scatter plot by measurement and simulation, and represents the physical extent of the influence of a particular property of the component on other components. When virtual representations of the respective components are moved relative to another in the e-detailing software for determining the physical positions of the components in the ITE hearing aid, the collision plot for a given component is visually displayed, so that it can easily be seen when another component invades that collision plot, thereby representing an unacceptably close relative position of the two components.

Abstract: A pin-based memory power modeling method using arc-based characterization includes steps as follows. All power arcs of a memory model are identified and characterized. A power arc is selected from the identified and characterized power arcs. Output bus switching power is computed by removing overlapping power using the selected power arc, and a temporary value for various input ramp times and output loads is derived. Output pin power for the selected power arc is calculated using the temporary value and a ratio of a number of output bits switching over an entire bus width. Switching power for the selected power arc is calculated by a power estimation tool based on port activity and an input intrinsic power value.
