SPOX-MATH
for TMS320C3x, TMS320C4x
by Spectron Microsystems

Software Overview

SPOX-MATH is one of several portable components of the SPOX family of products that provide a 
complete development environment for DSP application developers. SPOX-MATH consists of over 175 
optimized assembly language math functions for managing and manipulation array, vector, matrix, and 
filter objects. SPOX-MATH includes vector and matrix arithmetic, logical, signal processing, and 
digital filtering operations for floating point digital signal processors. Functions are overloaded 
so they work with matrices that contain integer, real, or complex data. SPOX-MATH is extensible, 
allowing developers to apply their own functions to SPOX data objects.
When SPOX-MATH is used in conjunction with SPOX-KNL, systems services are available that provide 
error messaging, debugging, trace buffers, and control over the location and alignment of data for 
maximum access speed. SPOX-KNL also supports I/O multitasking and dynamic memory allocation.
See also SPOX-KNL, SPOX-MP, SPOX-DBUG, and SPOX-LINK for information on related tools for DSP 
development.

Features and Benefits

•	Arithmetic functions perform basic mathematical operations and provide support for complex 
arithmetic and transcendental functions
•	Sophisticated mathematical functions are available to perform standard signal processing 
operations
•	Logical functions perform operations on integer vectors and matrices
•	Filter functions manage both the data and the attributes used to describe a finite impulse 
response or an infinite impulse response

Processor and System Specifications

Each set of functions is packaged as a library of C-callable functions, along with a set of header 
files that must be included by any application software using that component's functions. Programs 
are compiled and linked into executable images using
cross-development tools on a PC compatible or Sun workstation host, and are then moved onto the 
target hardware thorough a system-specific program loader or debug environment. 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
		10-MB hard disk space
            (Texas Instruments tools may impose additional requirements)
•	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

Availability

•	Software
		SPOX-MATH Run-Time Support Library is available for the TMS320C3x and TMS320C4x processors.
•	Documentation
		SPOX-MATH Programming Guide 
•	Warranty
		90-day warranty against defects in manufacturing. Maintenance agreements available separately 
from Spectron.
•	License
		One developer license and one run-time license for PC compatible computer or Sun workstation. 
Additional host license also available.

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.
