摘要： A communication interface device, system, method, and design structure for error correcting code (ECC) protected quasi-static bit communication (SBC) on a high-speed bus are provided. The communication interface device includes high-speed sampling logic to capture high-speed data from the high-speed bus using a high-speed sampling clock and SBC sampling logic to capture SBC samples from the high-speed bus using an SBC sampling clock. The SBC sampling clock is slower than the high-speed sampling clock. The communication interface device also includes an SBC finite state machine (FSM) to detect a received SBC command in response to a static pattern persisting for a predetermined number of the SBC samples and command decoding logic to decode the received SBC command.

A base clock operating at a base clock frequency is derived from the reference oscillator clock. A memory interface clock is derived by multiplying the base clock by a memory multiplier. A controller interface clock is derived by multiplying the base clock by a controller multiplier. The memory interface clock is applied to the memory interface and the controller interface clock is applied to the controller interface.
