7.8 Streaming Data Between Target and Host
Using the Configuration Tool, you can create 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 using the
Configuration Tool. Input channels transfer data from the host to the target,
and output channels transfer data from the target to the host.
