If too much interconnect is provided this requires more transistors than necessary and thus more silicon area, longer wires and more power consumption. One of the key challenges for reconfigurable computing is to enable higher design productivity and a more easy way to use reconfigurable computing systems for users that are unfamiliar with the underlying concepts.
One way of doing this is to provide standardization and abstraction, usually supported and enforced by an operating system. One of the major tasks of an operating system is to hide the hardware and present programs and their programmers with nice, clean, elegant, and consistent abstractions to work with instead. In other words, the two main tasks of an operating system are abstraction and resource management.
Abstraction is a powerful mechanism to handle complex and different hardware tasks in a well-defined and common manner.
One of the most elementary OS abstractions is a process. A process is a running application that has the perception provided by the OS that it is running on its own on the underlying virtual hardware. This can be relaxed by the concept of threads, allowing different tasks to run concurrently on this virtual hardware to exploit task level parallelism.
To allow different processes and threads to coordinate their work, communication and synchronization methods have to be provided by the OS.

Reconfigurable Computers offer the spatial parallelism and fine-grained customizability of application-specific circuits with the postfabrication programmability of software. Document, Internet resource Document Type: Partial re-configuration allows smaller reconfigurable bit streams thus not wasting energy on transmitting redundant information in the bit stream.

Some of the most intuitive designs use a peripheral bus to provide a coprocessor like arrangement for the reconfigurable array.
In addition to abstraction, resource management of the underlying hardware components is necessary because the virtual computers provided to the processes and threads by the operating system need to share available physical resources processors, memory, and devices spatially and temporarily.
