Abstract: A device comprises a central processing unit (CPU), a display controller configured for controlling a digital display and a memory configured for storing data corresponding to the digital display. The device includes a direct memory access (DMA) controller configured for autonomously transferring the data from the memory directly to the display controller without CPU intervention.

Abstract: Implementations are disclosed for a centralized peripheral access controller (PAC) that is configured to protect one or more peripheral components in a system. In some implementations, the PAC stores data that can be set or cleared by software. The data corresponds to an output signal of the PAC that is routed to a corresponding peripheral component. When the data indicates that the peripheral is “unlocked” the PAC will allow write transfers to registers in the peripheral component. When the data indicates that the peripheral component is “locked” the PAC will refuse write transfers to registers in the peripheral component and terminate with an error.

Abstract translation: 公开了针对被配置为保护系统中的一个或多个外围组件的中央外围设备访问控制器（PAC）的实现。 在一些实现中，PAC存储可以由软件设置或清除的数据。 该数据对应于被路由到对应的外围组件的PAC的输出信号。 当数据指示外设“未锁定”时，PAC将允许写入传输到外设组件中的寄存器。 当数据指示外设组件“锁定”时，PAC将拒绝对外设组件中的寄存器进行写入传输，并以错误结束。
