This application report describes differences between the Texas Instruments TMS320x2833x/2823x and the TMS320x2834x Delfino devices to assist in application migration. While the main focus of this document is migration from TMS320x2833x/2823x to TMS320x2834x, you will also find this document useful if you are considering migrating in the reverse direction. Functions that are identical in both devices are not necessarily included. All efforts have been made to provide a comprehensive list of the differences between the two device groups in the 28x generation; however, the descriptions are explained only to the extent of highlighting areas that require attention when moving an application from one device to another.
