7 / 52 page AD14160/AD14160L –7– REV. A Ten channels of DMA are available on the SHARCs—two via the link ports, four via the serial ports, and four via the processor’s external port (for either host processor, other SHARCs, memory, or I/O transfers). Four additional link port DMA channels are shared with serial port 1 and the external port. Programs can be downloaded to the SHARCs using DMA transfers. Asynchro- nous off-module peripherals can control two DMA channels using DMA Request/Grant lines ( DMAR1-2, DMAG1-2). Other DMA features include interrupt generation upon comple- tion of DMA transfers and DMA chaining for automatic linked DMA transfers. Development Tools The AD14160/AD14160L is supported with a complete set of software and hardware development tools, including an EZ-LAB ® In-Circuit Emulator, and development software. Analog Devices’ ADSP-21000 Family Development Software includes an easy to use Assembler based on an algebraic syntax, an Assembly Library/Librarian, a Linker, an Instruction-Level Simulator, an ANSI C optimizing Compiler, the CBug™ C Source-Level Debugger, and a C Runtime Library including DSP and mathematical functions. The Optimizing Compiler includes Numerical C extensions based on the work of the ANSI Numerical C Extensions Group. Numerical C provides exten- sions to the C language for array selection, vector math op- erations, complex data types, circular pointers and variably dimensioned arrays. The ADSP-21000 Family Development Software is available for both the PC and Sun platforms. The SHARC EZ-KIT combines the ADSP-21000 Family De- velopment Software for the PC and the EZ-LAB Development Board in one package. The ADSP-2106x EZ-ICE ® Emulator uses the IEEE 1149.1 JTAG test access port of the ADSP-2106x processor to monitor and control the target board processor during emulation. The EZ-ICE provides full-speed emulation, allowing inspection and modification of memory, registers and processor stacks. 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. Further details and ordering information are available in the ADSP-21000 Family Hardware & Software Development Tools data sheet (ADDS-2100xx-TOOLS). This data sheet can be requested from any Analog Devices sales office or distributor, or from the Literature Center. 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 PC plug-in cards, multiprocessor SHARC VME boards, and daughter card modules with multiple SHARCs and additional memory. These modules are based on the SHARCPAC™ module specification. Third party software tools include an Ada compiler, DSP libraries, operating systems and block diagram design tools. Other Package Details The AD14160/AD14160L contains 14 on-module 0.1 micro- farad bypass capacitors. It is recommended that in the target system at least four additional capacitors, of 0.018 microfarad value, be placed around the module—one near each of the four corners. The top surface, lid, of the AD14160/AD14160L is electrically connected to GND. Additional Information This data sheet provides a general overview of the AD14160/ AD14160L architecture and functionality. For detailed infor- mation on the ADSP-2106x SHARC and the ADSP-21000 Family core architecture and instruction set, refer to the ADSP-2106x SHARC User’s Manual.
