Hello every1, Can any one tell me as percentage of total area a very simple DMA unit might take on an embedded system. Some examples of such chips I believe are ARM 9, Motorola Mcore , IBM Cell. Any rough estimate or a reference would be highly appreciated.
thanks Sumesh
Your professor says to do your own homework (:
Stop and think about what a DMA controller needs:
A source address register A destination address register A transfer count register A status/command register
Random logic to gain control of the bus, do the transfer, stop the tranfer when the tranfer count register goes to zero and generate an interrupt.
