8 / 16 page REV. B –8– ADDS-21xx-TOOLS • EZ-LAB can be controlled from a host plugged into the Host Interface Port (HIP) connector when the EZ-LAB is running in a stand-alone configuration. • EZ-LAB can be controlled from software contained in a boot EPROM when the board is used in a stand-alone configuration. The ADSP-2171 interfaces directly to its program and data memories. The expansion connector may be used to interface to external devices. The DSP is also connected to indicator lights for data output and to pushbuttons for manual data input. Modular Analog Front End (MAFE) daughter cards can be connected to the ADDS-2171’s MAFE Interface Connector, allowing the DSP to communicate with a variety of I/O peripherals through memory mapped registers. Modular Analog Front End (MAFE) The MAFE specification provides a standard configuration for connecting analog I/O devices to MAFE compatible EZ-LAB products. This specification is used by Analog Devices and third-party vendors to design and manufacture add-on adapters which contain, for example, A/D and D/A converters. These A/D and D/A converters can communicate data either serially or on a parallel bus. These devices can also contain a number of internal control registers as well as some external control lines. If the MAFE device uses parallel data transfer, the memory location designated as the MAFE data is written to or read from in order to transfer data to/from the MAFE device. Data for a control register and data which represents the analog sample are both transferred in this manner. If the MAFE device uses a serial data transfer, the appropriate serial port of the DSP is used. Transfer of control data may also need to be done in a parallel fashion. ADSP-2100 Family EZ-ICE Emulators The ADSP-2100 Family EZ-ICE in-circuit emulators are used for testing and debugging an ADSP-21xx-based system. The EZ-ICEs make it easy to view and manipulate the data needed to debug your DSP applications. Table III lists the features of each version of EZ-ICE currently available for the ADSP-2100 family. Control and debug features include single-step capabilities, with or without register displays, and multiple breakpoint selections. At power-up, the host PC automatically resets and performs a diagnostic check to ensure that both host memory and the EZ- ICE are functional; it automatically displays any failures found. ADSP-2181 EZ-ICE TOOLS Features The ADSP-2181 EZ-ICE In-Circuit is a development tool for debugging programs running in real time on a target system based on the ADSP-2181. It includes all of the standard functionality of the other EZ-ICEs, with the added advantages of full speed emulation, a smaller connector interface, and ease of use. The ADSP-2181 EZ-ICE provides a simpler target board connection that requires fewer mechanical clearance considerations than other EZ-ICE Emulators by utilizing the ICE-Port™ emulation interface built into the ADSP-2181 (see Figure 3). The ICE-Port interface requires little more than a 14-pin header connector to implement it. All of the standard functionality of the other EZ-ICEs are provided, with the added advantages of full speed emulation, a very small connector interface, and ease of use. EZ-ICE Software Like the rest of the ADSP-2100 Family EZ-ICE Emulators, the ADSP-2181 uses the same EZ-ICE software and GUI interface design as the other EZ-ICEs and the ADSP-2100 Family Simulators. This makes the development process easier as the tools share so much commonality in use. ADSP-2101 AND ADSP-2111 EZ-ICE TOOLS Features These versions of the EZ-ICE are designed with a PGA connector protruding from the bottom of the probe board that fits into the processor socket on the target system. Connector adaptors for PQFP and TQFP are available. The ADSP-2101 EZ-ICE is also used in developing systems based on the ADSP- 2105, ADSP-2115, and ADSP-216x DSPs. Systems based on the ADSP-2111 use the ADSP-2111 EZ-ICE. EZ-ICE Software The ADSP-2101 and ADSP-2111 EZ-ICE Emulators use the same EZ-ICE software and GUI interface design as all of the ADSP-2100 Family EZ-ICEs and the ADSP-2100 Family Simulators. Development productivity is increased by making your data easier to view and manipulate when debugging. In addition, you can view relevant information without switching between screens and can obtain on-line help for the currently selected window. The user interface is similar to the one used with the ADSP-2100 Family Simulators, making both tools easier to use. ADSP-2171 EZ-ICE TOOL Features The ADSP-2171 EZ-ICE In-Circuit Emulator is a development tool for debugging programs running in real time on a target system based on the ADSP-2171 processor. This is made possible through the use of the ADDS-21xx EZ-ICE Board which differs from other EZ-ICE models in its use of a pair of dedicated header connectors that allow it to plug directly onto the target board and interface with the target DSP (see Figure 2) or to use an adaptor to clip onto the target DSP itself, depending on the device package used. EZ-ICE Software Like the rest of the ADSP-2100 Family EZ-ICE Emulators, the ADSP-2171 uses the same EZ-ICE software and GUI interface design as the other EZ-ICEs and the ADSP-2100 Family Simulators. This makes the development process easier as the tools share so much commonality in use. ICE-Port is a trademark of Analog Devices, Inc. |
