Low-Latency Bridge to Support Out-of-Order Execution - A simplified explanation of the abstract

This abstract first appeared for US patent application 18577636 titled 'Low-Latency Bridge to Support Out-of-Order Execution

Simplified Explanation

This document discusses systems and techniques for a low-latency bridge that supports out-of-order execution. The bridge allows a memory controller to process transaction requests from clients with minimal latency.

• The bridge can send a first transaction response without storing it in a reorder buffer.
• It can determine if the next transaction response is available to send to the client.
• Introduces latency to the larger system only when a secondary response of in-order transaction responses is received first.

Key Features and Innovation

• Facilitates out-of-order execution by a memory controller.
• Minimizes latency introduced by the bridge.
• Reduces the need for a large reorder buffer.

Original Abstract Submitted

This document describes systems and techniques for a low-latency bridge to support out-of-order execution. The described systems and techniques can facilitate out-of-order execution by a memory controller of in-order transaction requests. When it receives transaction responses associated with in-order transaction requests, the bridge can send a first transaction response without storing it in a reorder buffer. Similarly, the bridge can determine whether a next transaction response is available to send to the respective client. The bridge introduces latency to a larger system (e.g., an SoC) only when a secondary response (e.g., not first) of in-order transaction responses is received first. In this way, the memory controller can process transaction requests from one or more clients with minimal latency introduced by the bridge and a smaller reorder buffer.
