Many real-time applications require a high-resolution time tick in order to work properly. However, supporting a high-resolution time tick imposes a very high overhead on the system. In addition, such systems may need to change scheduling discipline from time to time to satisfy some user requirements such as Quality of Service (QoS). The dynamic changing of(More)
In this paper, we present a mechanism for runtime updating of all kernel modules of a highly modular dynamic real-time operating system. Our approach can help solve the lack of adaptability, extensibility, and flexibility of existing real-time operating systems. The dynamic real-time operating system will efficiently support a wide range of applications(More)
Previous work has shown that a system-on-a-chip lock cache (SoCLC) reduces on-chip memory traffic, provides a fair and fast lock hand-off, simplifies software, increases the real-time predictability of the system and improves performance. In this research work, we extend the SoCLC mechanism with a priority inheritance support implemented in hardware.(More)
In this paper, a software debugging mechanism for embedded systems is presented. The debugger is a dynamically loadable and linkable module of the operating system. The methodology presented in this paper provides automatic error detection, classification and location capabilities for a set of algorithmic errors. An example implementation of our approach is(More)
Software streaming allows the execution of stream-enabled software on a device even while the transmission/streaming may still be in progress. Thus, the software can be executed while it is being streamed instead of causing the user to wait for the completion of download, decompression, installation and reconfiguration. Our streaming method can reduce(More)
Wireless and embedded portable devices, such as cell phones and PDAs, place a premium on storage and communications bandwidth. The communications channel itself is prone to outages as well. However, users are expecting much more capability from these devices, including the ability to run business applications (e.g., Oracle), play video games, and also to(More)
