Method and apparatus for debugging a data processing system
A data processing system ( 10 ) includes a CPU ( 12 ) and debug circuitry ( 16 ). CPU ( 12 ) can execute instructions which provide direct input to one or more of trigger circuitry ( 32 ), multi-function debug counters ( 34 ), combining logic ( 36 ), and action select and control logic ( 38 ). Break...

| description | A data processing system (
10
) includes a CPU (
12
) and debug circuitry (
16
). CPU (
12
) can execute instructions which provide direct input to one or more of trigger circuitry (
32
), multi-function debug counters (
34
), combining logic (
36
), and action select and control logic (
38
). Breakpoints can be cascaded, and separate breakpoint sequences can be triggered from a same trigger. A selected trigger (
117
) can produce a resulting action or trigger (
119
) but only if it occurs in a predetermined order compared to one or more other triggers (
117
). Multi-function debug counters (
34
) can perform a wide variety of programmable functions, can be started and stopped using the same or separate triggers, and can be optionally concatenated with each other. |
