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

Software Overview

SPOX is a highly-modular and configurable operating system environment that can be tailored for a 
variety of different hardware platforms. An important benefit of SPOX is reusibilty, meaning that a 
tested and documented body of off-the-shelf software can be embedded in a wide range of systems and 
need not be redundantly developed with each new application.
SPOX-KNL, the core of the SPOX family of DSP products, is a deterministic real-time multi-tasking 
kernel designed to meet the demanding time and space requirements of DSP applications. SPOX-KNL 
consists of a collection of modules which can be used individually or together as building blocks 
in the development of DSP applications.
SPOX-KNL documentation includes sample programs and examples as well as a configuration guide and 
tools supporting memory, system and device configuration.  See also SPOX-MP, SPOX-DBUG, SPOX-LINK, 
and SPOX-MATH for more information on related tools for DSP development from Spectron.

Features and Benefits

•	Compact—as little as 1.5 kwords of code space
•	Interprocess communications
•	Priority-based, preemptive scheduling
•	Device-independent I/O; enhanced streaming I/O
•	Software interrupts: time slicing and custom schedulers

Processor and System Specifications

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
		1.2-MB floppy drive
•	SPOX-KNL for Sun-4 workstations
		SunOS version 4.1 (or higher)
		3.5-inch floppy drive
•	Platforms supported
		PC, Sun
•	Devices supported
		TMS320C3x, TMS320C4x, TMS320C5x, TMS320C8x

Company Background and Contact Information

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.
