In addition to the software and hardware development tools available from Analog Devices, third parties provide a wide range of tools supporting the SHARC processor family. Hard- ware tools include SHARC processor PC plug-in cards. Third party software tools include DSP libraries, real-time operating systems, and block diagram design tools. Designing an Emulator-Compatible DSP Board (Target) The Analog Devices family of emulators are tools that every DSP developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG test access port (TAP) on each JTAG processor. Nonintrusive in- circuit emulation is assured by the use of the processor’s JTAG interface. (The emulator does not affect target system loading or timing.) The emulator uses the TAP to access the internal fea- tures of the processor, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The processor must be halted to send data and com- mands, but once an operation has been completed by the emulator, the DSP system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the DSP’s JTAG port to the emulator. For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod logic, refer to the Analog Devices JTAG Emulation Technical Reference (EE-68) on the Analog Devices website, www.ana- log.com. (Perform a site search on “EE-68.”) This document is updated regularly to keep pace with improvements to emulator support. Evaluation Kit Analog Devices offers a range of EZ-KIT Lite ®† evaluation plat- forms to use as a cost-effective method to learn more about developing or prototyping applications with Analog Devices processors, platforms, and software tools. Each EZ-KIT Lite platform includes an evaluation board along with an evaluation suite of the VisualDSP++ development and debugging environ- ment with the C/C++ compiler, assembler, and linker. Also included are sample application programs, a power supply, and a USB cable. All evaluation versions of the software tools are limited for use only with the EZ-KIT Lite product. The USB controller on the EZ-KIT Lite board connects the board to the USB port of the user’s PC, enabling the VisualDSP++ evaluation suite to emulate the on-board proces- sor in-circuit. This permits the customer to download, execute, and debug programs for the EZ-KIT Lite system. It also allows in-circuit programming of the on-board flash device to store user-specific boot code, enabling the board to run as a stand- alone unit without being connected to the PC. With a full version of VisualDSP++ installed (sold separately), engineers can develop software for the EZ-KIT Lite or any cus- tom defined system. Connecting one of Analog Devices’ JTAG emulators to the EZ-KIT Lite board enables high speed, non- intrusive emulation. ADDITIONAL INFORMATION This data sheet provides a general overview of the processor’s architecture and functionality. For detailed informa- tion on the ADSP-2136x family core architecture and instruction set, refer to the ADSP-2136x SHARC Processor Hardware Reference and the ADSP-2136x SHARC Processor Programming Reference. RELATED SIGNAL CHAINS A signal chain is a series of signal-conditioning electronic com- ponents that receive input (data acquired from sampling either real-time phenomena or from stored data) in tandem, with the output of one portion of the chain supplying input to the next. Signal chains are often used in signal processing applications to gather and process data or to apply system controls based on analysis of real-time phenomena. For more information about this term and related topics, see the “signal chain” entry in the Glossary of EE Terms on the Analog Devices website. Analog Devices eases signal processing system development by providing signal processing components that are designed to work together well. A tool for viewing relationships between specific applications and related components is available on the www.analog.com website. The Circuits from the LabTM site (http://www.analog.com/signalchains) provides: • Graphical circuit block diagram presentation of signal chains for a variety of circuit types and applications • Drill down links for components in each chain to selection guides and application information • Reference designs applying best practice design techniques † EZ-KIT Lite is a registered trademark of Analog Devices, Inc. |
