Abstract :
Media processors, a new class of processor architectures that combine hardware and software to accelerate multimedia functions concurrently, owe their existence to several computational needs and enabling technologies. In this article, the author discusses the reasons for media processors existence, the implementation of the Mpact media processor, and some examples of the relationship between hardware and software on the Mpact chip
