Datapath

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A datapath is a collection of functional units such as arithmetic logic units or multipliers, that perform data processing operations, registers, and buses.[1] Along with the control unit it composes the central processing unit (CPU).[1]

During the late 1990s, there was growing research in the area of reconfigurable datapaths—datapaths that may be re-purposed at run-time using programmable fabric—as such designs may allow for more efficient processing as well as substantial power savings.[2]

The first is the datapath, which is a network of storage units (registers) and arithmetic and logic units... connected by buses... where the timing is controlled by clocks."
