Claim 15

Dependent Claim 31 words

The tool of claim 7 , wherein the graphical data analysis system is operable to selectively display a graph of created data as a constellation diagram or as an eye diagram.

Claim 16

Dependent Claim 47 words

The tool of claim 7 , wherein the graphical data analysis system is operable to continuously update a graph of created data buffer in response to a probe point associated with a selected program statement in the program being developed, such that a waterfall graph is formed.

Claim 17

Dependent Claim 80 words

An integrated code development tool for a host processor operable to develop a program executing on a target processor, comprising: an editor, a build system, a debugger, and wherein said editor is operable to provide a source code view which is simultaneously capable of integrating with said debugger to provide for stepping through code and setting breakpoints, and integrating with the output of said build system to display source code interleaved with corresponding assembler code created by said build system.

Claim 18

Dependent Claim 80 words

An integrated code development tool for a host processor operable to develop a program executing on a target processor, comprising: an editor, a build system, a debugger, and wherein said editor is operable to provide a source code view which is simultaneously capable of integrating with said debugger to provide for stepping through code and setting breakpoints, and integrating with the output of said build system to display source code interleaved with corresponding assembler code created by said build system.

Claim 19

Independent Claim 140 words

A method for developing a program for execution on a target processor using an integrated code development tool having a graphical user interface (GUI) operating on a host processor, comprising the steps of: writing the program using an editor contained within the tool; displaying source code of the program via the GUI interleaved with corresponding assembler code of the program created by a build system portion of the tool; placing a probe point in the program by selecting a line of the source code or a line of the assembler code via the GUI; executing the program to create a set of created data in response to a command from the tool; and displaying a graph of the created data on the GUI using a data analysis portion of the tool while the target processor continues to run the program.

Claim 20

Independent Claim 140 words

A method for developing a program for execution on a target processor using an integrated code development tool having a graphical user interface (GUI) operating on a host processor, comprising the steps of: writing the program using an editor contained within the tool; displaying source code of the program via the GUI interleaved with corresponding assembler code of the program created by a build system portion of the tool; placing a probe point in the program by selecting a line of the source code or a line of the assembler code via the GUI; executing the program to create a set of created data in response to a command from the tool; and displaying a graph of the created data on the GUI using a data analysis portion of the tool while the target processor continues to run the program.
