Abstract
Three-dimensional (3-D) processor devices are provided, which are constructed by connecting processors in a stacked configuration. For instance, a processor system includes a first processor chip comprising a first processor and a second processor chip comprising a second processor. The first and second processor chips are connected in a stacked configuration with the first and second processors connected through vertical connections between the first and second processor chips. The processor system further includes a mode control circuit to selectively operate the processor system in one of a plurality of operating modes. For example, in a one mode of operation, the first and second processors are configured to implement a run-ahead function, wherein the first processor operates a primary thread of execution and the second processor operates a run-ahead thread of execution.
