Arm DSTREAM高性能调试和跟踪单元可在任何基于Arm处理器的硬件目标上实现强大的软件调试和优化。
借助用于许多开发平台的加速硬件启动和用于第三方工具的开放式调试接口等功能,DSTREAM调试器在与Arm Development Studio配合使用时为复杂SoC的开发和调试提供了全面的解决方案。

Support for Armv8

Support for Armv8

Arm构建的调试和跟踪直到Armv8。 无论是经典还是最新产品,DSTREAM都涵盖了它。

 

lightning Fast Trace

Lightning Fast Trace

使用HSSTP跟踪探针进行高达19.2 Gbps的并行跟踪或高达20 Gbps的串行跟踪。

 

lightning Fast Trace

Extended Trace Buffer

即使在最快的目标上捕获扩展跟踪,也可以获得软件执行的详细信息。

DSTREAM DSTREAM-ST DSTREAM-PT
Debug connectivity JTAG and Serial-Wire Debug
Arm processor support

Any Arm processor based hardware target up to Armv8 with CoreSight trace supported

Functionality Debug, parallel trace Debug, streamed trace Debug, parallel trace
On target trace Yes Yes  Yes
External parallel trace 9.6 Gbps (up to 16 pins) 2.4Gbps (up to 4 pins) 19.2Gbps (up to 32pins)
External serial trace Trace can either be collected using the default parallel trace probe supplied with DSTREAM or alternatively, using the High-Speed Serial Trace Probe (HSSTP), available separately. This allows for high bandwidth serial trace capture of up to 20 Gbps from Arm HSSTP or Marvell® SETM. - -
