There is an increasing interest in using reconngurable hardware for performing computational tasks. Yet despite this interest, there are no suitable metrics for comparing the performance of reconngurable systems. We propose that the core encryption of the International Data Encryption Algorithm (IDEA), a popular 128-bit block cipher, be used for this purpose. We implemented the IDEA algorithm o...
