Answer - The benefits of placing functionality in the device controller are: - System crasher due to the occurrence of a bug is greatly reduced. - By the utilization of dedicated hardware and algorithms that are hard coded the performance can be improved greatly. - Since the algorithms are hard coded the kernel gets simplified. The banes of placing functionality in the controller rather than the kernel are: - Once a bug occurs they are difficult to fix, a new firmware or revision may be required. - For performance improvement of algorithms hardware upgrades are required rather than a device driver update.
