Abstract :
This paper analyzes various fast 2D-DCT algorithms regarding their suitability for VLIW processors. Operations for truncation or rounding which are usually neglected in proposals for fast algorithms have also been taken into consideration. Loeffler´s algorithm with parallel multiplications was found to be most suitable due to its parallel structure
