ASICs, processors, and configurable computing

Summary form only given. It is often suggested that configurable computing represents a new computational middle ground that fills the existing void between conventional microprocessors and ASICs. This point of view is based upon the observation that FPGAs share some similarities with both processors and ASICs. FPGAs are seen as similar to processors because they are customized in the field by the end user by downloading configuration data into the device. They can also be seen as similar to ASICs because they can implement high performance, application specific circuits. It is hoped that if configurable computing can be shown to be similar to conventional processors, it will be possible to borrow microprocessor architecture and compilation techniques for use in the configurable computing community
