Anni: SAGA DMA Core

Overview

The SAGA Core contains the Anni Core, which is an advanced DMA controller that can perform fast I/O operations independent of the CPU.

Currently, it is used by the on-board Ethernet driver for the Vampire Standalone. In the future, it can be used for other I/O devices, such as IDE storage devices and SD cards, if the appropriate drivers are written.


Features

  • Supports 64-bit reads.
  • Supports full cache coherency. Data transfers automatically update all CPU caches.
