The Arm CoreSight ELA-500 provides an effective way to observe low-level signals, by offering a way to zoom into the root cause of data corruption. You can program the ELA-500 to trigger signal capture in response to a particular event, in addition to causing triggers elsewhere in the SoC to further help with the debug process.

一、coresight coresight是ARM公司提出的，用于对复杂的SOC，实现debug和trace的架构。 该架构，包含了多个coresight组件。 众多的coresight组件，构成了一个coresight系统。

Arm next generation ELA with extended AMBA Trace Bus interface for streaming trace data, accelerates high precision debug. ELA-600 shortens system debug cycle by providing larger window for SoC signals observation.

The ELA is a component of CoreSight™ which provides low-level signal visibility into Arm IP and third party IP. The ELA allows you to monitor any signal that is part of an implementation-defined Signal Group. This can include loads, stores, speculative fetches, cache activity, and transaction life …

Arm Flexible Access gives you quick and easy access to this IP, relevant tools and models, and valuable support. You can evaluate and design solutions before committing to production, and only pay when you are ready to manufacture.

Arm CoreSight ELA-500 提供觀察低階訊號的有效方法，即提供方式以聚焦檢視資料毀損的根本原因。 您可以編程 ELA-500 來觸發訊號擷取以因應特定事件，另外也可以觸發 SoC 中的其他區域來進一步協助除錯過程。

CoreSight ELA-600 improves data tracing efficiency with optimized signal monitoring, customizable triggers, and options for trace data storage.
