EASE
Debugging Support for CAST Processor Cores

The Evatronix Aplication-Debugging Support Environment (EASE) gives you a complete solution for debugging embedded software directly in a target system. It includes:

• a processor-specific core implementing the on-chip debug controller (OCDS), which reaches into the processor to control its program execution and read/write memories and registers,
• a software plug-in that translates debugging requests from popular tools like those from Keil and Tasking, and
• a data exchange interface between the debug hardware and your personal computer, using the standard four-pin JTAG connection.

EASE thus gives you considerable control over the system under test through the familiar interface of your favorite debugging tool.

You can easily control execution — start, reset, stop, go and step — and set a variety of hardware and software breakpoints. You have full access to all memories and registers in the system, reading to or writing from each at will. And you benefit from the observability and monitoring features of your PC-based debugger.

The OCDS on-chip controller easily integrates with your processor core and is designed to be very efficient. The R8051XC2 ASIC version, for example, requires just 5,500 extra gates (for two breakpoints).
