Description Embedded systems require the development and debug of software. The process to debug the embedded software is a complex and time-consuming issue. The real-time nature of the applications causes issues that continue to make the debug process more complex. This complexity occurs when the user does not have access to the internal operation of the microprocessor. External measurements are available. As cache is added to the microprocessor, the ability to obtain instruction and data information from the external bus is minimized. This proposal is for a non-intrusive method of embedded system debug using hardware and measurement information about the system. Hardware architecture information includes the hardware architecture of the microprocessor used and the software under test. Additionally, measurement data is added from external measurements. The premise for the non-intrusive method of debug combines the known information with measurements made from the system under test. Applications include multi-tasking and parallel processing. This proposal is a continuation of a previous initial case study. The initial study utilized a Motorola 68020 performing a variety of functions including: simple subroutines, interrupts, and a form of multi-tasking. Several simplifications were made to accomplish the initial study. This included not using a high level language like C, but coding specific routines in assembly to accomplish the tasks required. The 68020 was selected since it had instruction cache and a pipelined architecture as well as being representative of a "high performance processor". The continuation would include more detailed software applications, as well as more structured coding methods and higher language development. |

Description AgentSheets Inc. is engaged in the commercialization of AgentSheets software, an advanced simulation development environment developed at and licensed from the University of Colorado. We believe that AgentSheets simulations and models represent a new and unusually effective learning tool for corporate training, education, and lifelong learning. AgentSheets software has won numerous national and international awards and represents a decade-long research effort. Various government agencies and private firms have invested over $3 million in the development of AgentSheets software and tools. AgentSheets commercialization has focused on the K-12 education market. We want to move into the corporate training market, and we are actively seeking corporate partners. We want to collaborate with private industry on using AgentSheets technology to solve their most challenging corporate training problems. We are interested in precisely defining the "AgentSheets advantage" in corporate training, and we need concrete and quantitative examples that show AgentSheets software addressing corporate needs. We will present the features of AgentSheets software, along with its advantages for corporate training, in the context of a collaborative corporate training project. Specifically, we will present a project in which we develop AgentSheets simulations, models, and tools that solve corporate training problems defined by our corporate partner. Our partner utilizes our training tools and quantitatively evaluates their performance. This will give us corporate training marketing materials and credibility. We hope that our CASI presentation will help us locate partners. |

Description Haptic Courtyard is a virtual environment facilitating the study of cognitive maps, wayfinding and navigation for the blind. Our goal is to allow the visually impaired to navigate the real world with comfort and ease. This research is an outgrowth of our earlier experiments for shape learning in a virtual environment using sound cues.

Description Big projects experience cost overruns and schedule slips so routinely we accept such events with knowing cynicism. Truth is, honest attempts to accurately predict costs and completion dates are far more likely to fall short than we realize. This research explains some under-appreciated forces that drive projects and the resulting effects on project performance. |
