The development and implementation of efficient algorithms




The higher the DSP performance, then it can run within a certain period of time greater the number of algorithm cycles, and be able to handle more complex algorithms. Blackfin BF50x outstanding performance and a sufficiently large on-chip memory (4 MB executable flash memory), allowing designers to use more sophisticated algorithms to achieve a more robust system capabilities and more precision.



For example, for solar power inverter applications, the inverters can be a complex algorithm to the fluctuating DC output is converted to "clean" current, as well as residential and urban photovoltaic (PV) cells produce an array into the commercial power grid and / or local grid current to adjust. Maximum Power Point Tracking (MPPT) algorithm can extract the maximum individual and / or series of energy generated by solar panels, designers typically use a variety of MPPT algorithm to adapt to a variety of environmental factors. Blackfin BF50x processor, the excellent signal processing performance adequate to deal with the complexity of the MPPT algorithm, to ensure the realization of ultra-high efficiency power converter applications extract, while the prices are pretty, low-power processors and the MCU is difficult to competence.



For motor control applications, the ability to handle complex algorithms to ensure that the system behavior according to changes in the implementation of real-time dynamic control in order to obtain a more stable operating characteristics and lower power consumption. The use of a sensorless Field Oriented Control (FOC) algorithm, then the permanent magnet synchronous motors can be (PMSM) the implementation of variable speed control, thereby enhancing energy efficiency, and the motor without the need to speed and position sensor (sensorless vector control). Based on the Blackfin BF50x designed to take advantage of advanced modeling algorithms that can accurately determine the rotor position and speed, and without the use of position / speed sensor, so that the system smaller, lower cost, reliability is even higher.
