Dynamically reconfigurable FPGAs are well known to combine the flexibility of software with the performance of application specific hardware. As such they can be used as powerful but still flexible coprocessors in embedded processor systems. In this paper we analyze different variants for interfacing reconfigurable hardware from an embedded processor. We describe three different on-chip busses and evaluate their usability for dynamically reconfigurable systems. In addition, we analyze the communication latencies and the speed-up factor of a hardware accelerator for floating point operations for a total of eight different coupling variants.
