摘要： An apparatus and method for evaluating a state of an electronic or integrated circuit (IC), each IC including one or more processor elements for controlling operations of IC sub-units, and each the IC supporting multiple frequency clock domains. The method comprises: generating a synchronized set of enable signals in correspondence with one or more IC sub-units for starting operation of one or more IC sub-units according to a determined timing configuration; counting, in response to one signal of the synchronized set of enable signals, a number of main processor IC clock cycles; and, upon attaining a desired clock cycle number, generating a stop signal for each unique frequency clock domain to synchronously stop a functional clock for each respective frequency clock domain; and, upon synchronously stopping all on-chip functional clocks on all frequency clock domains in a deterministic fashion, scanning out data values at a desired IC chip state. The apparatus and methodology enables construction of a cycle-by-cycle view of any part of the state of a running IC chip, using a combination of on-chip circuitry and software.

摘要： A system for encrypting and decrypting data is provided. The system includes a client for receiving a data packet, setting a value of a crypto bit, and transmitting the data packet over a system bus. A crypto module receives the data packet from the system bus and performs a cryptology function on the data packet based on a first value of the crypto bit. A memory controller receives the data packet from the system bus and performs non-cryptology functions on the data packet based on a second value of the crypto bit.
摘要翻译：提供了一种用于加密和解密数据的系统。该系统包括用于接收数据分组的客户端，设置密码比特的值，以及通过系统总线发送数据分组。加密模块从系统总线接收数据分组，并根据加密比特的第一值对数据分组执行密码学功能。存储器控制器从系统总线接收数据包，并且基于密码比特的第二值在数据包上执行非密码学功能。
