Generic Memory Emulator DCI-GME1Calibration and measurement of ECU variables

Key Features Independent of microcontroller and ECU

Installation inside or outside the ECU enclosure

Calibration and measurement of ECU variables

Direct connection to host PC

High data throughput via USB

Description Application AreasThe DCI-GME1 (dSPACE Calibration Interface- Generic Memory Emulator) provides access to the ECU variables for calibration and measurement. The DCI-GME1 is highly versatile, supporting a wide range of microcontrollers and electronic control units (ECUs). The memory emulator can be installed on or in the ECU and connected to the microcontroller bus via a target adapter.

Key BenefitsDirect access to the address and data bus allows maximum bandwidth for data acquisition. Typically the ECU’s read-only (flash) memory for calibration parameters is replaced by the emulation RAM on the DCI-GME1. The generic memory emulator can be connected directly to the host PC (using USB). To meet vehicle safety requirements, a special USB communication protocol with error detection and correction was implemented, as well as a USB optoisolation integrated in the USB cable.

Generic Serial Interface DCI-GSI1

Measurement, calibration, and ECU function bypassing

Key Features ECU adaptation via connector adapter and firmware update

Compact size, installation inside or outside the ECU enclosure

Fast ECU flash programming

Direct connection to host PC via USB for measurement and calibration

Arbitration logic for parallel access of debuggers

Low-latency LVDS interface to dSPACE prototyping systems for bypassing

Description Application AreasFor processor bus architectures with less external or off-chip visibility, dSPACE provides a generic serial interface (GSI) which supports different on-chip debug ports for measurement, calibration, and bypassing. Adaptation to a specific electronic control unit (ECU) can be done via an individual connector adapter and a firmware update on the DCI-GSI1.

Operation ModesFor measurement, the DCI-GSI1 supports two strategies: with ECU service (data aquisition is triggered by a small piece of code included in the ECU code) and without ECU service (data aquisition is triggered by an ECU event). For example, data capturing can be triggered via digitial I/O pins of the microcontroller or by the GSI, which is capable of detecting write accesses to specific ECU memory addresses. In addition, it is also possible to perform measurements according to the GSI‘s on-board timer. To calibrate ECU parameters, the DCI-GSI1 supports both overlay units that are provided by the ECU´s micro-controller and an external RAM for the calibration data. During bypassing, the DCI-GSI1 performs the data transfer and triggers the bypass system, which calculates the controller function outside the ECU. If bypass, calibration, or measurement accesses to the ECU are requested at exactly the same time, the GSI gives bypass access the highest priority. This way, minimal latencies in communication between the ECU and the prototyping system are always guaranteed without compromising the measurement band-width.

DS541 DPMEM POD for MPC55xxVersatile top board for MPC55xx-based VertiCal architecture

Key Features Off-the-shelf top board for MPC55xx VertiCal base boards from Freescale

DPMEM bypass interface with minimal communication latencies

Additional SRAM for calibration data

On-board JTAG/Nexus connector for calibration, measurement, or debugging

VertiCal connector to add further top boards

Description Application AreasControl algorithms for electronic control units (ECUs) in modern vehicles can be developed and optimized efficiently by the external bypassing method. This involves calculating selected ECU functions on powerful and flexible prototyping hardware (e.g., MicroAutoBox or AutoBox), while the remainder of the code continues to run, unmodified, on the existing ECU. The DS541 serves as an ECU interface for function bypassing using the integrated dual-port memory (DPMEM) and the high-speed LVDS interface to the exter-nal prototyping system. In addition, the DS541 supports ECU calibration, and it provides an inter-face for ECU debugging or flash programming.

Key BenefitsThe DS541 minimizes communication latencies between the prototyping hardware and the electronic control unit (ECU). This makes it ideal for bypassing ECU functions that require fast execution rates and a large number of model inputs and outputs. The DS541 is a top board for MPC55xx VertiCal Base Boards from Freescale, which can be connected to the ECU simply by installing a base board in place of the ECU’s original microcontroller. Low latencies, com-bined with high signal integrity, are achieved by several factors: direct access to the microcontroller bus via the VertiCal connector, very short signal line lengths between the dual-port memory and the MPC55xx, and a fast LVDS interface. The available Simulink blocksets support two variants of external bypassing: address-based and service-based bypassing. The DS541‘s additional SRAM allows the POD to be used as a memory for calibration data. If the POD’s voltage supply is connected to the vehicle battery, the SRAM data is retained after the ECU is switched off. As a calibration interface, for example, the ECU‘s CAN bus or the JTAG/Nexus interface available on the DS541 itself can be used. The DS541’s VertiCal connector allows further plug-on boards to be connected, for example, for memory emulation.

Description

Bypass Interfaces Supported by dSPACE Including Customer-Specific Solutions

Application AreasWhen the bypass method is used for rapid con-trol prototyping, there are often several possible ways of diverting the flow of data from the ECU to the prototyping system and back. In cases where a dSPACE standard bypass interface is not applicable, a customer-specific plug-on de-vice (POD) may be a suitable solution. dSPACE offers a wide range of options for such PODs, meeting the needs of numerous microcontroller types and individual applications. We recommend you consult us on bypassing issues at an early project stage, to gain maximum benefit from one of dSPACE’s standard solutions and significantly reduce engineering costs.

Key BenefitsFrom many years of experience with bypass interface development, dSPACE has a long list of well proven solutions to offer. You can also order a custom bypass interface, precisely tailored to the microcontroller of your production ECU and your application.
