The Chip Support Library (CSL) provides an application programming interface (API) used for configuring and controlling the DSP on-chip peripherals for ease of use, compatibility between various C54xx devices and hardware abstraction. This will shorten development time by providing standardization and portability. The functions listed in the features section are specifically designed for all the C54xx DSPs including C5401, C5402, C5402A, C54CST, C5404, C5407, C5409, C5409A, C5410, C5410A, C5416, C5420, C5421, C5440, C5441 and C5471(dsp side)
