title: T-head TH1520 Mailbox Controller



description:

  The T-head mailbox controller enables communication and coordination between

  cores within the SoC by passing messages (e.g., data, status, and control)

  through mailbox channels. It also allows one core to signal another processor

  using interrupts via the Interrupt Controller Unit (ICU).
