    • In a host-slave data transfer system, the slave device transmits data regarding its status and buffer conditions to the host using tailers inserted into the data being transferred to the host. The slave device has a plurality of buffers, a buffer management circuit which manages the buffers and obtains buffer condition information (e.g. amount of available buffer space, amount of buffered data to be transferred to the host), a detection circuit which collects interrupt status of the slave, a processing circuit which generates headers or tailers containing the buffer conditions information and interrupt status, and a merging circuit which merges multiple data segments received from the data-source/data-destination device and associated headers and tailers to generate a stream of merged data. The host obtains the buffer condition information from the tailers, and uses it to determine the amount of data to transmit or receive from the slave.
    • 在主从数据传输系统中,从设备使用插入到正在传送给主机的数据中的分机向宿主发送关于其状态和缓冲器条件的数据。 从设备具有多个缓冲器,缓冲器管理电路管理缓冲器并获得缓冲器条件信息(例如可用缓冲器空间量,要传送到主机的缓冲数据量),检测电路,其收集中断状态 从设备,产生包含缓冲器条件信息和中断状态的报头或分机的处理电路,以及合并电路,其合并从数据源/数据 - 目的地设备和相关联的报头和分配器接收的多个数据段,以产生流 合并数据。 主机从尾随机获取缓冲条件信息,并使用它来确定从从站发送或接收的数据量。

    • An embedded system with authentication includes: a system read only memory (ROM), a processing circuit and an authentication circuit. The system ROM is arranged to store a boot code. In addition, the processing circuit is arranged to process at least according to the boot code in order to perform operations of the embedded system. Additionally, the authentication circuit is arranged to perform authentication on a command script in order to determine whether the command script is authenticated, and is arranged to prevent the command script from being executed by the processing circuit when the authentication circuit determines that the command script is not authenticated, wherein the command script is received from outside a chip where the system ROM, the processing circuit and the authentication circuit are positioned.
    • 具有认证的嵌入式系统包括:系统只读存储器(ROM),处理电路和认证电路。 系统ROM被安排为存储引导代码。 此外,处理电路被布置为至少根据引导代码进行处理,以便执行嵌入式系统的操作。 此外,认证电路被配置为对命令脚本执行认证,以便确定命令脚本是否被认证,并且被布置成当认证电路确定命令脚本是否为命令脚本时,防止命令脚本被处理电路执行 未认证,其中从系统ROM,处理电路和认证电路所在的芯片外部接收命令脚本。
