....accesses, the necessary support consisted mainly of the ability to suspend the FPGA clock and to read write all of the data state from outside the chip. Haug and Rosenstiel have reported on a system using the 6200 as an external accelerator that is time shared along with the rest of the system [33, 34]. 4.3 Implementation study As the Garp architecture has never been implemented and tested physically, it is necessary to question how e#ectively it could be realized in standard VLSI. Our main interest is to assign estimates for chip area, speed, and power consumption, so that the Garp ....

....as well as an operating systems perspective. Many FPGA devices support multiple contexts by providing on chip memory for storing inactive configurations and state (see, for example, 3] but time sharing can also be managed in software by swapping contexts off chip (see, for example, [10]) When multiple contexts are supported in hardware, the active context is usually selected by a globally broadcast context instruction. Overheads are small with this method, and the potential exists to pass data in place between the configurations. Pre loading configurations into the area ....
