  2. Essence (1) • What applications are potentially migratable to Maxeler? • Extra long execution time. • Most of the execution time is in loops. • What loops to migrate? • High data reusability, once the data is moved to the accelerator. • High tolerance to long latencies, by the application. • What acceleration to expect? • If below the hardware limits,the more data,the higher the expected acceleration (good for Big Data) • The less sophisticated the data dependencies of different loop iterations, the higher the expected acceleration.
