8051 & 68000 IP Core debug systemEASE Application Debugging Support for 8051 Microcontroller and 68000 Microprocessor Cores

Debug your software applications running on our 8051 MCU and 68000 µP cores with EASE (the Evatronix Application-Debugging Support Environment).

The EASE package combines hardware and software to provide complete, in-system control and debug of the core while an application executes. EASE is simple to connect and configure via a standard USB 2.0 interface, and it works with popular tools from Keil and TASKING.

EASE includes:

• A processor-specific block in the core that implements the On-Chip Debug Support (OCDS) controller, which reaches into the processor to control its program execution and read/write memories and registers.
• A processor-specific Debug Interface (EDIk51-3 for 8051s) that runs on a Windows PC and translates debugging requests between popular debugging like those from Keil and Tasking and the core.
• A hardware Debug Pod (EDP). This connects to the PC via USB, and to the processor core on a board via standard four-pin JTAG or optionally for the R8051XC2 single-pin SWORD.
• EDIServer, a PC application that transmits data from the debugger to the EDP unit. It supports TCP/IP, enabling remote debugging over a standard network.

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).
