or from the host by way of DMA transfer. The DSP can supply data to ether the outgoing
data stream or the host by way of DMA transfer.
6 API Supported Physical Devices
6.1 Board Devices
The Sleipnir configuration and status registers are accessible by API calls. The board
devices include the serial to parallel converters and the DMA controller. The application
can read or write the data directly from the Sleipnir buffers, or have the DMA controller
place the data in the host memory and notify the application when data is available.
6.2 T1/E1 Line Interface Device
The Sleipnir Line Interface device fully supported by API calls to configure the interface
for the required functionality. There is full access to all device registers for monitoring or
diagnostics.
6.3 DSP
The optional DSP on the Sleipnir can be used to run Odin provided standard DSP
applications or they can be used to run user developed custom applications. The Sleipnir
telecom configuration is delivered with a number of Odin’s Signal Processing Module
(SPM). These SPMs, or DSP application packages, provides supports for many common
telecom applications; such as tone detection and generation, FSK detection, and HDLC
sending and receiving.
