• Optimized power management circuitry (instruction-dependent, peripheral-dependent, and mode-

dependent).

Packaging

Feature

Description

Real-Time

Operating System

(RTOS)

The real-time operating system (RTOS) fully supports device architecture (multi-core, memory hierarchy,

ICache, timers, DMA, interrupts, peripherals), as follows:

• High-performance and deterministic, delivering predictive response time.

• Optimized to provide low interrupt latency with high data throughput.

• Preemptive and priority-based multitasking.

• Fully interrupt/event driven.

• Small memory footprint.

• Comprehensive set of APIs.

• Fully supports DMA controller, interrupts, and timer schemes.

Multi-Core Support

• Enables use of one instance of kernel code all four SC140 cores.

• Dynamic and static memory allocation from local memory (M1) and shared memory (M2).

Distributed System

Support

Enables transparent inter-task communications between tasks running inside the SC140 cores and the

other tasks running in on-board devices or remote network devices:

• Messaging mechanism between tasks using mailboxes and semaphores.

• Networking support; data transfer between tasks running inside and outside the device using networking

protocols.

• Includes integrated device drivers for such peripherals as TDM, UART, and external buses.

Software Support

• Incorporates task debugging utilities integrated with compilers and vendors.

• Board support package (BSP) for the application development system (ADS).

• Integrated Development Environment (IDE):

• C/C++ compiler with in-line assembly. Enables the developer to generate highly optimized

DSP code. It translates code written in C/C++ into parallel fetch sets and maintains high

code density.

• Librarian. Enables the user to create libraries for modularity.

• C libraries. A collection of C/C++ functions for the developer’s use.

• Linker. Highly efficient linker to produce executables from object code.

• Debugger. Seamlessly integrated real-time, non-intrusive multi-mode debugger that

enables debugging of highly optimized DSP algorithms. The developer can choose to

debug in source code, assembly code, or mixed mode.

• Simulator. Device simulation models, enables design and simulation before the hardware

arrival.

• Profiler. An analysis tool using a patented Binary Code Instrumentation (BCI) technique that

enables the developer to identify program design inefficiencies.

• Version control. CodeWarrior® includes plug-ins for ClearCase, Visual SourceSafe, and

CVS.

Boot Options

• External memory.

• External host.

•UART.

•TDM.
