Real-Time Multi-Tasking Operating System

CMX CompanyTX for DSP Group's Teak DSP Core is a real-time multi-tasking operating system for Microprocessors, Microcomputers and DSPs that incorporates many features with a very small code size.

The RTOS provides application developers with more than 70 kernel services within a single API. It features the CMX Function library, which gives users the ability to control tasks, events, messages, resources, cyclic timers, semaphores, queues, and fixed memory blocks. The RTOS allows developers to schedule runable higher priority tasks, to preempt lower priority tasks and to use both cooperative and time-slice scheduling. The RTOS also lets interrupts call CMX functions. The scheduler and interrupt handler are written in assembly code, delivering speed and performance optimization.

The Teak DSP Core is a member of the TeakDSPCore family. Teak is a dual MAC 16-bit fixed-point licensable DSP with code compactness. It provides a solution for low-power, speech and audio processing, wireless communication, modems, advanced telecommunication systems, disk drive controllers and various embedded control applications. The Teak DSP Core is binary backward code -compatible with the industry standard OakDSPCore from DSP Group. The core is designed as a soft core and in a single- edge clocking system, which allows the use of full or partial scan-testing methodologies. The core supports emulation, debugging and testing via JTAG.
