Arm DSTREAM高性能調試和跟蹤單元可在任何基于Arm處理器的硬件目標上實現強大的軟件調試和優化。
借助用于許多開發平台的加速硬件啓動和用于第三方工具的開放式調試接口等功能,DSTREAM調試器在與Arm Development Studio配合使用時爲複雜SoC的開發和調試提供了全面的解決方案。

Support for Armv8

Support for Armv8

Arm構建的調試和跟蹤直到Armv8。 無論是經典還是最新産品,DSTREAM都涵蓋了它。

 

lightning Fast Trace

Lightning Fast Trace

使用HSSTP跟蹤探針進行高達19.2 Gbps的並行跟蹤或高達20 Gbps的串行跟蹤。

 

lightning Fast Trace

Extended Trace Buffer

即使在最快的目標上捕獲擴展跟蹤,也可以獲得軟件執行的詳細信息。

 

 

lightning Fast Trace

Flexible Debug

適用于JTAG,CoreSight,TI和MIPI的適配器。 與第三方IP和調試器兼容,爲您提供最大的靈活性。

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. - -
