Energy Consumption of an Internal CRC Module in a Microcontroller

Abstract

In the current scenario with the Internet of Things looming on every aspect and activity of daily life, the need for the interconnection with information grids is inevitable. Information from one device to another, to others, is always happening and thus, are prone to transmission errors. To mitigate these errors, CRC can be used. The added error checking feat is also an issue since the device will need to code and decode the checksum. This research presents the energy consumption of a microcontroller with an internal Cyclic Redundancy Check module. Such microcontroller is the PIC24FV32KA302 from Microchip. An energy profile was used to determine the behavior of microcontroller using a CRC-16 configuration.
