High-Speed Simultaneous

Transfer

High-Speed Simultaneous Transfer (HSST) facilitates data transfer between low-level

targets (hardware or simulator) and host-side client applications. The data transfer

occurs without stopping the core.

The host-side client must be an IDE plug-in or a script run through the command-line

debugger.

When the customer links their application to the target side hsst lib, the debugger

detects that the customer wants to use hsst and automatically enables hsst

communications.

NOTE

To use HSST, you must launch the target side application through the

debugger.

Host-Side Client Interface

This section describes the API calls for using High-Speed Simultaneous Transfer

(HSST) from your host-side client application.

At the end of this section, an example of a HSST host-side program is given (Listing

9.1).

hsst_open

A host-side client application uses this function to open a communication channel with

the low-level target. Opening a channel that has already been opened will result in the

same channel ID being returned.
