Abstract :
The JPEG architectures in literature do not implement many features defined in the standard, useful in several wireless applications, such as noise protection, components management and the possibility to change a lot of encoder parameters. The addition of these features alters the computational cost of the encoder, and this could lead to problems when the power consumption is a primary concern. In this work we use Powersim to check the influence of these features on the computational cost of a JPEG encoder with some new features and for different implementations of some of its modules.
