Migrating from TMS320VC5402A to TMS320VC5502

This document describes issues of interest related to migration from the TMS320VC5402A to the TMS320VC5502. The objective of this document is to indicate differences between the two devices. Functions that are identical between the two devices are not included. For detailed information on the specific functions of either device, refer to the following data manuals and reference guides: TMS320VC5402A Fixed-Point Digital Signal Processor Data Manual (SPRS015), the TMS320VC5502 Fixed-Point Digital Signal Processor Data Manual (SPRS166), the TMS320C54x DSP Reference Set, Volume 1 (SPRU131), the TMS320C54x DSP Reference Set, Volume 5 (SPRU302), the TMS320C55x DSP CPU Reference Guide (SPRU371), and the TMS320C55x DSP Peripherals Reference Guide (SPRU317).

Migration issues from the TMS320VC5402A to TMS320VC5502 are indicated with the following symbols:

1. [S]
means software modification is required.
2. [H]
means hardware modification is required.
3. [D]
means the VC5402A and VC5502 are different but no modification is necessary for migration (i.e., different but compatible).
4. [N]
means the VC5502 adds new features that are not available on the VC5402A

These symbols are included at the beginning of each section.
