Abstract

The method of partial reconfiguration of Compositional Microprogram Control Units implemented on FPGAs is proposed. The method is based on the swapping of the content of Control Memory while the rest of the system is not modified. Such approach permits to decrease the size of a bit-stream that is sent to the device. Therefore time needed for device configuration is shorter. Proposed solution is much more safe due to less errors that can occur during reconfiguration of FPGAs. An example of proposed method application is discussed. The researches conducted by authors have shown that proposed method permits to decrease the size of a bit-stream that is sent to the device in comparison with traditional method even up to 95%.
