U ky .ed U ,and rew-ta n7@ hotmai I .com Abstract Critical to run-time processor resource allocation, reconfiguration, and control of a reconfigurable heterogeneous single-chip multiprocessor architecture is a defined multifunctional queue required by each processor of the architecture. The multifunctional queue implements six functions required for control, resource allocation, and reconfiguration within the architecture.
In addition to normal queue functionality of First In First Out (FIFO) operation and empty,@ll indicator, the multifunctional queue implements the additional non-common functions of indicating when queue depth has reached a programmable threshold level, it indicates queue occupancy level at all times, it continually indicates queue input rate over a programmable time interval, it continually indicates queue input rate change over a programmable time interval and it can implement a pseudo-RAM function.An analytic functional model of the queue is first presented then an organization, architecture and design is developed followed by the development of appropriate analytic real-time performance metrics for the queue.Both virtual and Field Programmable Gate Array (FPGA) based prototypes of the queue are then developed and used for functional, maximum frequency, and/or performance model testing resulting in verification of desired queue functionality and performance. A contribution of the queue is its functional versatility which would allow its use in computer architectures or processors other than the described target architecture.
The focus of this paper is on the broad extension of multi-spectral color to both scientist and consumer by creating camera/projector arrays composed of commodity hardware. In contrast to expensive, high-maintainance systems which rely on the physical registration of device spaces, we rely on the virtual alignment of viewing spaces in software where real-time alignment is achieved using the processing capacity of the graphical processing units of consumer PC video cards. Specifically, this paper focuses on the inclusion of real-time, composite pattern, structured light illumination (SLI) as a means of recording the 3D shape of objects, which will then be used for the registration of single-color images taken from multiple view points simultaneously. As such, the described system is able to achieve a cost per unit that scales linearly with the number of color primaries.
