In a recent undertaking, the aim was to connect a microcontroller with a specialized DSP chip for our processing needs. The microcontroller was assigned the responsibility of collecting data from data-gathering sensors, and the DSP incorporated almost all operational instantaneous calculations meant for processing and interpreting such data. The main criteria were communication protocols, power loads, and bandwidth of data interchange. Since the successful coordination of both chips' communication was imperative, we chose a sensible option in which both chips could interface - SPI (Serial Peripheral Interface). Power management was also a critical aspect; we had to consider the power levels of each chip in order not to have overheating problems, and that required regulated voltages. Last but not least, since the data transfer rate had to be equivalent to the processing capability of the DSP, adjustments to clock rates and data buffering had to be made in order to eliminate the possibility of delays or data loss. Such a configuration meant that there was a need to maintain a suitable combination of compatibility, power levels and timing in order to achieve efficient and reliable data processing that operates on high speeds.
