ColdFire® DSP Library Reference Manual, Rev 0.4

PublishTime：2022-05-19

■Introduction
●The ColdFire DSP Library contains digital signal processing algorithms optimized for the ColdFire architecture. These algorithms are implemented directly in assembly for computational efficiency and then encapsulated into a simple C interface. In addition, a large number of predefined and pretested filter configurations are provided in order to reduce the need for a user to design digital filters.
●The library is designed to enable embedded sensor applications with basic signal processing functionality, but without the need for a DSP co-processor. By taking advantage of an on-chip multiply-accumulate unit (MAC), a ColdFire microcontroller can efficiently execute DSP algorithms. A typical user may wish to sample an analog sensor (such as an accelerometer) with an analog-to-digital converter (ADC) at a particular rate, filter out unwanted signal components (such as high-frequency noise or other interfering signals), and then use the result in the target application for monitoring, status, data-logging, or control capabilities. The ColdFire DSP Library greatly simplifies the digital filtering part of the process.
