Centralized Timestamp Module for Graphics Engine Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Graphics processing systems with multiple engines face inefficiencies in managing and accounting for timestamps, leading to complex and cumbersome operations for graphic drivers.
Innovation Solution
A centralized timestamp processing system is implemented, where a timestamp module is integrated with multiple engines, allowing the driver to assign tasks, write command packets to memory buffers, and signal completion to the timestamp module, which writes timestamps to a shared memory accessible by the driver.

1Productivity
If each engine maintains its own timestamp for processing task requests, then each engine can independently track task completion, but the driver must maintain and account for every timestamp which becomes complicated and inefficient
Solution Approach 1:
The patent merges the timestamp management function from individual engines into a centralized timestamp module. Each engine still maintains its own timestamp for tracking task completion, but all timestamps are collected and managed by a single centralized module in the driver. This consolidation reduces the driver's complexity by providing a unified interface for timestamp accounting across all engines, eliminating the need for the driver to individually manage and reconcile multiple independent timestamp systems.
2Device complexity
If a centralized timestamp module is introduced to simplify driver operations, then driver complexity is reduced, but additional hardware components and memory buffers are required
Solution Approach 1:
The centralized timestamp module is designed to serve multiple functions within the graphics processing system. It acts as a universal timestamp management interface that handles timestamp collection, accounting, and synchronization for all engines simultaneously. By making the timestamp module multi-functional, the patent reduces the need for separate dedicated timestamp handling mechanisms for each engine, thereby simplifying the overall system architecture despite adding centralized management capability.
Solution Approach 2:
The centralized timestamp module functions as an intermediary between the engines and the driver. It receives timestamps from multiple engines and provides a unified interface for the driver to access and account for all timestamps. This intermediary layer absorbs the complexity of coordinating multiple timestamp sources, allowing the driver to operate with simplified logic while the timestamp module handles the intricate synchronization and accounting details.
3Productivity
If multiple engines operate concurrently with centralized timestamp management, then processing performance increases, but timestamp synchronization and accuracy become more challenging
Solution Approach 1:
The centralized timestamp module implements feedback mechanisms to maintain accuracy under concurrent operations. Each engine signals the timestamp module when tasks are completed, and the module uses this feedback to correctly associate timestamps with their corresponding tasks. The read pointer mechanism provides feedback about which timestamps have been processed, allowing the system to maintain accurate tracking even as multiple engines operate concurrently and submit completion signals at different rates.
Data Source
AI summary
Method and apparatus for centralized timestamp processing is described herein. A graphics processing system includes multiple graphics engines and a timestamp module. For each task, a graphics driver assigns the task to a graphics engine and writes a task command packet to a memory buffer associated with the graphics engine. The graphics driver also writes a timestamp command packet for each task to a timestamp module memory buffer. A command processor associated with the graphics engine signals the timestamp module memory buffer upon completion of the task. If the read pointer is at the appropriate position in the timestamp module memory buffer, the timestamp module/timestamp module memory buffer executes the timestamp command packet and writes the timestamp to a timestamp memory. The timestamp memory is accessible by the graphics driver.
