Comparison of Third Generation DSP Platforms (3GDSP)

This project is conducted in cooperation with local industry (ETI, DigiAnswer and NOKIA). The term 3G DSP is used in the sense of the state-of-the-art processors well suited for modern DSP applications. This may include processors typically referred to as digital signal processors as well as modern controllers featuring DSP possibilities, and general-purpose micro-processors. For that purpose, 3 platforms have been selected ("plat-form" is defined as processor and compiler) and analysed (TMS320C55x,TigerSHARC, ARM9E-S). Some case studies have been defined for analysis of the platforms (GSM EFR, Matrix Functions, Dhrystone, CVSD, Viterbi). Results clearly indicate that General Purpose Processors with DSP-extensions (such as ARM) are a viable alternative to dedicated DSP-processors (such as TI C55x) under the constraints considered in this project. See CPK Annual Report 2001 - Figure 4.2.2.1 (Cycle count and code size (bytes) for different coding style optimisations for the FIR filter kernel for the TMS320C55x platform).
