A well-known example of an I/O co-processor is the Raspberry Pi’s PIO. It consists of a set of four “processors”, each with nine instructions, with an instruction memory of 32 locations, highly tuned to provide great flexibility with easy cycle-accurate manipulation of GPIOs. For example, an SPI implementation with clock, in, and out consists of a configuration modifier plus just two instructions that are executed in an “effective loop,” due to configurable side-effects available in the PIO configuration, such as automatic code wrap-around and FIFO management:
幸运的是，随机熵的本质允许我们将多个来源混合使用，从而使得最终结果的质量等同于最佳输入源的质量。因此，即使某个源不佳，也只有在所有源都出问题时才会导致麻烦。我们还有两个有利条件：(a)我们仅需要唯一性，而非密码学级别的安全性，这降低了对熵源进行额外严格审查的需要，并允许我们采用准随机方法；(b)准随机方法极大减少了对熵总量的需求，因此获取每单位熵的性能开销几乎可以忽略不计。基于此，我整合了以下几种熵源：
