channel interface是用来使不同coresight组件之间传递event使用。使用两个组件来实现: CTM: cross trigger matrix, 接收CTI的channel信号,然后广播给其他CTI CTI:cross trigger interface, 接收trigger信号,发送trigger信号,接收channel信号,发送channel信号 参考: Arm CoreSight Architecture Specification v3.0 Arm CoreSight System-on-Chip SoC-600 ARM CoreSight Debug and Trace Coresight(一)core...
[导读]摘 要:以ARM Core Sight Architecture Specification规范和ARM Debug Interface Architecture Specification规范为出发点,分析了ARM CoreSight调试与追踪体系在ARM Cortex M3内核中的实现过程。同时,对比分析了新的Serial WireDebug调试技术和经典的JTAG调试技术的异同。 引言 在芯片制造技术飞速发展的今天,高速、高集...
对应Arm的产品线,我们可以认为Coresight架构的实现是Coresight SoC系列IP,而ADI架构的实现则是DP/AP(也被包含在Coresight SoC中)。 也就是图中虚线框起来的部分,都属于Coresight SoC组件的范畴,这个package往往与core一起license给客户——对应地,core是Arm架构的实现。 Arm架构中的debug feature与处理器无论在结构...

下面以一个简化SoC中的debug function框图来表明Arm ARM/Coresight/ADI这三种架构在一个真实系统中的所负责的范围,以及它们之间的关系。 Figure 0-2 Debug architecture in a real system 橙色是AD define 如图注所示,这张示意图中的三种主要颜色分别代表了三种架构定义的实现。
ETM-M23 is compatible with the CoreSight architecture. ETM-M23 implements version 3.5 of the ETM architecture, ETMv3.5. See the Embedded Trace Macrocell Architecture Specification for more information. For more information about architectural compliance, see Architecture and protocol information.This...
The Arm CoreSight System Trace Macrocell (STM) is a trace source that enables real-time software instrumentation with no impact on system behavior or performance. It extends the low-cost real-time visibility of software and hardware execution to all software developers, enabling rich, optimized and...
For more information on TPIU frame synchronization, see the Arm® CoreSight™ Architecture Specification v3.0. It is also possible for a downstream CoreSight™ trace component to control when synchronization packets are generated by the ITM on ATB using the input SYNCREQI signal. Local time...
