چکیده

This paper presents MEDIATOR, a feature recognition system which is designed to be maintainable and ex-tensible to families of related manufacturing processes. A problem in many feature recognition systems is that they are diicult to maintain. One of the reasons may be because they depend on use of a library of feature-types which are diicult to update when the manufacturing processes change due to changes in the manufacturing equipment. The approach taken by MEDIATOR is based on the idea that the properties of the manufacturing equipment are what enable manufac-turable shapes to be produced in a part. MEDIATOR's method for identifying features uses a description of the manufacturing equipment to simultaneously identify manufacturable volumes (i.e. features) and methods for manufacturing those volumes. Maintenance of the system is simpliied because only the description of the equipment needs to be updated in order to update the features identiied by the system.

Recon gurable Computing: Architectures, Models and Algorithms

The performance requirements of applications have continuously superseded the computing power of architecture platforms. Increasingly larger number of transistors available on a chip have resulted in complex architectures and integration of various architecture components on the chip. But, the incremental performance gains obtained are lower as the complexity and the integration increase. Recon...

Physical Design for Recon gurable Computing Systems using Firm Templates

The advances in the programmable hardware has lead to new architectures where the hardware can be dynamically adapted to the application to gain better performance. There are still many challenging problems to solve before any practical general-purpose recon gurable system is built. One fundamental problem is the placement of the modules on the recon gurable functional unit (RFU). Here, we are ...

Constant-Time Hough Transform on a 3D Reconfigurable Mesh Using Fewer Processors

The Hough transform has many applications in image processing and computer vision, including line detection, shape recognition and range alignment for moving imaging objects. Many constant-time algorithms for computing the Hough transform have been proposed on recon gurable meshes [1, 5, 6, 7, 9, 10]. Among them, the ones described in [1, 10] are the most e cient. For a problem with an N N imag...
