New App Note AN010 (Snorkel)

App Note AN010, The Snorkel Mark 1: A Programmable DMA Channel, has been newly issued. This application note describes a simple SRAM master that moves arbitrary sequences of 18-bit or 16-bit data between one of its COM ports and specified areas of the external SRAM. This is done by a simple, software-defined special purpose processor that executes a stored program from SRAM to define the sequence of transfers. The Snorkel is used by the polyFORTH system.
