2. PRODUCT OVERVIEW

This chapter contains a general overview of APIS.

2.1. INTRODUCTION

AcQ produces and supports a large number of standard M-modules varying from networking and

process I/O to motion control applications. Physically, the M-modules are supported by a large

number of hardware platforms: VMEbus, PCI, CompactPCI as well as a wide variety of operating

systems: OS-9, Windows NT, Linux etc.

APIS offers a way to program platform independent applications, example- and test software for

controlling hardware. Application software written for APIS only needs re-compiling for a particular

platform and is operational with little effort (provided that the application is operating system

independent).

Although APIS is described as a software interface for M-modules it is applicable in a wide variety of

implementations, whenever hardware has to be controlled by software. For example PCI cards, IP

modules or an integrated device on a processor board.
