Precise/MQX+m
by Precise Software Technologies Inc.

Software Overview

Precise/MQX+m is a portable, royalty-free, distributed processor real-time executive designed for 
embedded-DSP applications. Precise/MQX+m contains all of the features of the single-processor 
real-time executive Precise/MQX. Any application that runs on MQX will automatically run on MQX+m 
simply by relinking the application. MQX+m supports any configuration of processors and includes 
drivers for inter-processor connection via comm ports, VMEbus chips, and FIFOs. If the 
inter-processor drivers can not be used, then a developer can easily implement a proprietary 
driver. MQX+m is supported with tools that provide performance measurement, and multiprocessor 
task-level debugging and applications can use the Precise Embedded I/O Components.
