683xx: Definition and Recommended Links

Our favorite links for this topic area. Enjoy, fellow researchers! Questions, comments, new links? Email eewindow@aol.com!.

The Freescale 683XX (formerly Motorola 683XX) is a family of compatible microcontrollers that use a Freescale 68000-based CPU core. The family was designed using a Hardware Description Language, making the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.

There are two CPU cores used in the 683XX family: the 68EC000 and the CPU32. The instruction set of the CPU32 core is similar to the 68020 without bitfield instructions, and with a few instructions unique to the CPU32 core, such as table lookup and interpolate instructions, and a low-power stop mode.

The modules of the microcontroller were designed independently and released as new CPUs could be tested. This process let the architects perform 'design-ahead' so that when silicon technlogies were available, Motorola had designs ready to implement and go to market. Many of these submodules have been carried forward into the Coldfire line of processors.

      RTXC Quadros RTOS -- flexible, adaptable, configurable

      The RTXC Quadros RTOS family is four highly scalable real-time operating systems with distinct advantages for each of the major processing models. RTXC/ss utilizes a lightweight executive for signal processing. RTXC/ms is optimized for control processing with an event-driven, prioritized scheduler. RTXC/dm (dual mode) is ideal for convergent processing which combines DSP/dataflow and RISC/control processing in a single-core. RTXC/ms and RTXC/dm are brought together in RTXC/mp to support multicore/multiprocessor.

      RTOS UH: Real-Time Operating System for Process Automation

      Programming system PEARL RTOS-UH was designed for the special requirements found in process automation and automatic control and is based on the processor families MC 68xxx, MC 683xx as well as on the PowerPC. RTOS-UH offers the same programming and real-time environment regardless which hardware is used - from the smallest single board MC 68008 up to the high-end PowerPC 604 VME-bus system.
