TMS 109A Socket 7 Microprocessor Support
The Socket 7 support has six additional fields: Code Segment Size, Interrupt
Table, Interrupt Table Address, Interrupt Table Size, Trace Processor, and Other
Processor. These fields appear in the area indicated in the information on basic
operations.
Code Segment Size. You can select the default code size: 32-bit or 16-bit. The
default code size is 16 bit.
Interrupt Table. You can specify if the interrupt table is Real, Virtual, or Protected.
(Selecting Virtual is equivalent to selecting Protected.) The default is Real.
Interrupt Table Address.
You can specify the starting address of the interrupt table
in hexadecimal. The default starting address is 0x00000000.
Interrupt Table Size.
You can specify the size of the interrupt table in hexadecimal.
The default size is 0x400.
Trace Processor.
You can select to disassemble data from the Primary or Dual
microprocessor. The default is Primary.
Processor.
You can specify either Intel or AMD depending on the socket7
processor that is under test. The
TMS 109A Socket 7
support has been tested with
both these microprocessor venders.
Other Processor.
The “other” microprocessor is the one not being traced (not
selected in the Trace Processor field). You can select to display or to suppress its
bus cycles.
When acquiring data from a system under test with two microprocessors, the
disassembler can trace the execution flow of one microprocessor and display the
hardware cycle types of the microprocessor not being traced. This means that the
software disassembles only the instructions executed from the microprocessor
being traced.
You can trace instructions from either the Primary microprocessor or the Dual
microprocessor. You can also choose to display or not display (suppress) data
from the microprocessor not selected in the Trace Processor field of the
Disassembly property page (Disassembly Format Definition overlay).
To set up the mode of tracing, you need to set the Trace Processor and Other
Processor fields in the Disassembly property page. Table 2–4 shows the
combinations of Trace Processor and Other Processor field selections and their
effects.
