Patent number: 9381364Abstract: Methods for optimizing telemetry in an implantable medical device system are disclosed, with the goal of equating and maximizing the communication distances between devices in the system, such as the external controller and the Implantable Pulse Generator (IPG). The method involves computerized simulation of maximum communication distances in both directions between the two devices while varying at least two parameters of the telemetry circuitry, such as the number of turns in the telemetry coils in the two devices. This results in a simulation output comprising a matrix in which each element comprises the bidirectional distance values. An element is determined for which the distances are equal (or nearly equal) and maximized (or nearly maximized), and the optimal values for the parameters are then chosen on that basis, with the result that the communication distance in one direction equals the communication distance in the other direction, and is maximized.Type: GrantFiled: August 31, 2011Date of Patent: July 5, 2016Assignee: Boston Scientific Neuromodulation CorporationInventors: Md.

Patent number: 9342334Abstract: A system and method for simulating new instructions without compiler support for the new instructions. A simulator detects a given region in code generated by a compiler. The given region may be a candidate for vectorization or may be a region already vectorized. In response to the detection, the simulator suspends execution of a time-based simulation. The simulator then serially executes the region for at least two iterations using a functional-based simulation and using instructions with operands which correspond to P or less lanes of single-instruction-multiple-data (SIMD) execution. The value P is a maximum number of lanes of SIMD exection supported both by the compiler. The simulator stores checkpoint state during the serial execution. In response to determining no inter-iteration memory dependencies exist, the simulator returns to the time-based simulation and resumes execution using N-wide vector instructions.Type: GrantFiled: June 22, 2012Date of Patent: May 17, 2016Assignee: Advanced Micro Devices, Inc.Inventors: Bradford M.
