7.8 Streaming Data Between Target and Host
You can configure host channel objects (HST objects), which allow an
application to stream data between the target and files on the host. In
DSP/BIOS analysis tools, you bind these channels to host files and start
them.
DSP/BIOS includes a host I/O module (HST) that makes it easy to transfer
data between the host computer and target program. Each host channel is
internally implemented using an SIO stream object. To use a host channel,
the program calls HST_getstream to get the corresponding stream handle,
and then transfers the data using SIO calls on the stream.
You configure host channels, or HST objects, for input or output. Input
channels transfer data from the host to the target, and output channels
transfer data from the target to the host.
