Today Litronic AG is announcing the immediate availability of the SCIOPTA Real-Time Operating System for the Motorola MCF5282 microcontroller.
SCIOPTA ColdFire is entirely written in assembler which results in a very high performance and a low memory footprint. The code size of 24 kbytes allows to use SCIOPTA ColdFire also in pure single-chip applications.
The pre-emptive multitasking real-time kernel supports the standard SCIOPTA message-based architecture and includes a module concept.
Beside the fast real-time kernel there are IPS (SCIOPTA Internet Protocols, TCP/IP), Web Server, SFFS (SCIOPTA Flash File System) and USB support available.
SCIOPTA ColdFire is royalty free and supports actually the C/C++ compilers and environments from GNU GCC and Metrowerks. A precompiled version of GCC ColdFire is included in the SCIOPTA CD delivery.
The MCF5282 is the first microcontroller based on Freescale Semiconductor’s 32-bit ColdFire core integrated with Ethernet, Flash and CAN. This device offers advanced communications features, a rich peripheral set and a variety of supporting software and development tools.
The MCF5282 is designed to simplify embedded Ethernet-networked microcontroller applications. With its integrated 10/100 Mbps Ethernet MAC and network-ready applications software, the MCF5282 can bring standards-based networking to a variety of traditional MCU applications including food service equipment, security systems, vending machines, exercise equipment and industrial controllers. Applications in all of these areas will benefit from networking functions such as Web-based user interfaces, network time synchronization, and router/gateway functionality for legacy serial protocols.
In 1994, the innovative ColdFire Microprocessor Family was added to Freescale’s Legacy 68K Family tree. This new variable-length RISC 68K Family architecture delivers the aggressive price/performance required by the cost-sensitive embedded market. In striving to meet the needs of the market with this innovative architecture, Freescale evaluated high-level source code from many 68K embedded systems customers. Based on the results of this study, a reduced instruction set and addressing modes were identified which created an efficient environment for processor operation. Like most RISC processors, the majority of ColdFire processor instructions execute in a single cycle.
