SPOX-DBUG 
for TMS320C3x, TMS320C4x, TMS320C5x, TMS320C8x
by Spectron Microsystems

Software Overview

SPOX-DBUG is one of several portable components of the SPOX family of products that provide a 
complete development environment for DSP application developers.  SPOX-DBUG extends the 
capabilities of the Texas Instruments powerful C Source debuggers, db30, emu40, db50, and mpemu. 
SPOX-DBUG enhances the TI debuggers and makes them SPOX-aware with features that simplify the 
development and debugging of real-time multi-tasking SPOX applications. By integrating with the 
Texas Instruments C Source debuggers, the developer can debug SPOX applications in a familiar 
environment with TI's embedded emulation tools. See also, SPOX-KNL, SPOX-MP, SPOX-MATH, and 
SPOX-LINK for information on related tools for DSP software development.

Features and Benefits

•	Supports interactive inspection and modification of any SPOX object (tasks, semaphores, streams, 
arrays)
•	Interactive invocation of SPOX-KNL system calls enables a developer to dynamically change the 
flow of  execution of their application
•	Provides both task-specific and application-wide breakpoint setting
•	TI's debugger provides a complete set of powerful non-intrusive debug capabilities
•	Complements the instruction cycle of the TI debuggers by providing overall system performance 
measurements 

Processor and System Requirements

SPOX application programs are generated on a host computer system using version 4.6 of the C 
compiler, assembler, and linker available from Texas Instruments.  Some facility must be provided 
for loading executable program images from your host computer on to your target hardware. Minimum 
host system configurations are as follows:

•	SPOX-KNL for PC-based systems:
		386-compatible processor (or higher)
		DOS version 5.0 (or higher)
		4-MB memory

Company Background

Spectron Microsystems, founded in 1987, is the leading provider of DSP system software and DSP 
integration services to multimedia, commercial embedded and military embedded customers.  Based in 
Santa Barbara, California, the company was the first independent software vendor to manufacture and 
sell products for programmable 32- and 16-bit Digital Signal Processing chips.  From the 
introduction of SPOX in 1988 to the present, Spectron has maintained its leadership through 
on-going R&D efforts in support of the latest DSP silicon, DSP hardware and DSP applications. In 
1995, Spectron Microsystems became a wholly owned business unit of Dialogic Corporation, 
Parsipanny, New Jersey.
