About: Debug port

An Entity of Type: settlement, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

A debug port is a chip-level diagnostic interface (akin to a computer port) included in an integrated circuit to aid design, fabrication, development, bootstrapping, configuration, debugging, and post-sale in-system programming. In general terms, a debug port is not necessary for end-use function and is often hidden or disabled in finished products. Due to their high complexity, debug ports are nearly universal in microprocessors (CPUs) and microcontrollers (MCUs). These are discussed below.

Property Value
dbo:abstract
  • A debug port is a chip-level diagnostic interface (akin to a computer port) included in an integrated circuit to aid design, fabrication, development, bootstrapping, configuration, debugging, and post-sale in-system programming. In general terms, a debug port is not necessary for end-use function and is often hidden or disabled in finished products. When constituted in a high availability or safety critical system, a debug port may continue to operate as a system monitor for integrity validation in the finished product. In low-cost or high-volume electronics, debug ports are sometimes left enabled to avoid costs of design changes, and can be used by modders and hackers to gain control of the device and/or access to extra functionality. Due to their high complexity, debug ports are nearly universal in microprocessors (CPUs) and microcontrollers (MCUs). These are discussed below. (en)
  • 除錯埠（Debug port）是電子設備上為了簡化開發及除錯而預留的接口。為了避免而產生的成本，一般而言不會移除除錯埠，而駭客或也常會透過除錯埠而取得設備的額外機能。 例子 * 集成电路上的JTAG埠 * 原始Xbox上的LPC匯流排除錯埠 * 串列除錯（Serial Wire Debug） * * Atmel AVR的程式及除錯介面 * (zh)
