User Interface

The TMS320C10 emulator unit was designed to work with IBM PC compatible computers. Its Windows user interface includes: a pop-up Status window for internal Registers; windows for Internal and External Memory; source code window with single stepping, breakpoints, fast calls and skip; full screen edit; user defined, movable windows; nine user defined setups hold Breakpoint, Trace and Event information for easy recall from disk.

Complex Events

Complex Event is a set of conditions that control the operation of complex program breakpoints and trace start/stop logic in real time. There are three TMS320C10 events available, each consisting of the combination of the following:

• 8K address breakpoints or ranges (64K on USP-16);
• Data pattern with less than, greater than, equal, not equal, and don't care combinations;
• RD, WR, I/O, and Instruction Fetch as qualifiers;
• External input with programmable polarity and gate.

In addition, Events can be counted/delayed by the use of two 16 bit Pass Counters. On the on the TMS320C1 emulator, an eight level hardware sequencer is available to sequentially trigger from/to any Event or Pass Counter.

Breakpoints

TMS320C1 emulator breakpoints are set to stop user program execution preserving the current program status. They can be triggered from a combination of:

• Simple address match or address range;
• Three Complex Events;
• External input;
• Two Pass Counters;
• Sequencer;
• Watchdog timer;
• Trace full condition;
• Trace buffer.

Trace Buffer

Trace buffer is a high speed RAM used to capture in real time all activity on the microprocessor internal bus and pins. A dedicated start/stop logic allows for filtering unwanted information from the TMS320C10 trace buffer. Buffer will remember the selected 32K samples comprised of the following:

• Internal Address Bus (12 + 4 external bits);
• Internal Data Bus (16 bits);
• BIO, INT, DEN, WE pins;
• Real Time Clock Stamp;
• User logic inputs (8 bits).

Trace can be started/stopped by the combination of:

• GO command;
• Any Event;
• Any Pass Counter;
• Sequencer;
• Trace Full condition.

Additionally, the TMS320C10 trace buffer is equipped with a special internal counter to allow tracing to stop after a specified number of instructions or cycles. This feature allows Trace to catch as much as 8K/32K of small fragments (snapshots) of executed program at full running speed. The Trace contents can also be examined during the execution without slowing down the microcontroller.
