Communication Channels for a Stacked Die Configuration

原文（中文）

Temporary system adjustment for communication channels for a stacked die configuration is described. In accordance with the described techniques, a system includes a first die that has one or more communication channels for transporting data to a destination across the first die, a switch configured to communicably couple to a second die stacked on the first die, and steering logic configured to route the data to the destination via the switch and over one or more communication channels of the second die. If the second die is detected, the steering logic is configured to route data to the destination over the communication channels of the second die and/or over the communication channels of the first die. If the second die is not detected, the steering logic is configured to route data to the destination over the communication channels of the first die.
