摘要： An SOC implements a security enclave processor (SEP). The SEP may include a processor and one or more security peripherals. The SEP may be isolated from the rest of the SOC (e.g. one or more central processing units (CPUs) in the SOC, or application processors (APs) in the SOC). Access to the SEP may be strictly controlled by hardware. For example, a mechanism in which the CPUs/APs can only access a mailbox location in the SEP is described. The CPU/AP may write a message to the mailbox, which the SEP may read and respond to. The SEP may include one or more of the following in some embodiments: secure key management using wrapping keys, SEP control of boot and/or power management, and separate trust zones in memory.

摘要： An integrated circuit (IC) implements an industry standard-defined peripheral interconnect to connect to another integrated circuit or component in a system. The industry standard specification includes a software interface that is well-defined and implemented by various software in the system, and thus is desirable to retain. However, the physical interconnect in the systems employing the integrated circuit may be short, and thus the elaborate physical layer definition may consume more integrated circuit area and power than is otherwise desirable in the IC. The IC may implement a simpler and more power-efficient physical layer, reducing both power consumption and semiconductor substrate area consumption, in some embodiments.

摘要翻译：集成电路（IC）实现工业标准定义的外围互连以连接到系统中的另一集成电路或组件。行业标准规范包括由系统中的各种软件明确定义和实现的软件接口，因此是可取的。然而，采用集成电路的系统中的物理互连可能很短，因此精细的物理层定义可能消耗比IC中其它方面所需要的更集成的电路面积和功率。在一些实施例中，IC可以实现更简单和更节能的物理层，从而降低功耗和半导体衬底面积消耗。
