Direct Memory Access (DMA) interfaces are a common and important component of Hardware/Software (HW/SW) interfaces between peripheral devices and their device drivers. We present a HW/SW co-validation framework to validate DMA interface implementations of a device and its driver. This framework employs a virtual prototype of the device as a reference model and performs co-validation in two stages:...
High-quality tests for post-silicon validation should be ready before a silicon device becomes available in order to save time spent on preparing, debugging and fixing tests after the device is available. Test coverage is an important metric for evaluating the quality and readiness of post-silicon tests. We propose an online-capture offline-replay approach to coverage evaluation of post-silicon validation...
Virtual prototypes are increasingly used in device/driver co-development and co-validation to enable early driver development and reduce product time-to-market. However, drivers developed over virtual prototypes often do not work readily on silicon devices, since silicon devices often do not conform to virtual prototypes. Therefore, it is important to detect the inconsistences between silicon devices...
This demonstration focuses on seamless video delivery over Wireless Mesh Networks with Dynamic Stream Merging (DSM) capability. The overall setup consists of a prototype with seven nodes forming the mesh network backbone. All these nodes run DSM software with mobility support. DSM is a robust technique that can reduce both gateway load and wireless traffic for video applications. It has the intelligence...
