(1) Debugger

The debugger is a software support tool designed to realize virtual D2SP functional circuits. In this virtually

emulated D2SP environment, user application programs can be evaluated as if they were executed on the real chip.

The debugger is used mainly for logics analysis and detailed data analysis.

Major functions of the debugger are listed in the table below, with brief explanation for each.

· Display and Edit instructions

These instructions can be used to display the contents of memory and registers on a screen and to update them.

· Memory Fill instruction

This instruction is used to fill a specified memory address range with a desired value.

· Move instruction

This instruction is used to transfer the data in a specified memory address range to another range.

· Memory Load and Save instructions

These instructions are used to transfer data between memory and disk. The memory load instruction enables the

data transfer from a disk file to memory while the memory save instruction allows the data transfer from memory

to a disk file.

· Assemble and Unassemble instructions

The assemble instruction is used to convert mnemonics into machine codes.

The unassemble instruction is used to convert memory data back to mnemonics.

· Emulation instruction control instruction and Break point instruction

These instructions are used to execute the D2SP program and trace its operations. The break point instruction is

used to set a point where the program execution stops.
