MEMO-Cube

The MEMO-Cube is the communication and pre-processing part of the 2nd generation terminal equipment managing the DAB and GSM networks. It is connected through a wireless LAN to a PC host (the application terminal) running the MEMO applications. It is a system for mobile trials. Therefore, no moving parts are used. It is designed to allow operation in an automotive environment.

Integrated into this PC/104 system are a DAB module based receiver card with the DABMOS on board, a DAB data extraction unit, a wireless LAN interface, a GSM connection interface and a overall control module.

The DABMOS is the second generation of BOSCH DAB-Receivers, developed outside the MEMO project. This module allows for building a highly integrated DAB radios.

The full DAB-date rate up to 1.7 Mbit/s can be decoded.

The Cube Software runs with the Operating System LINUX. This software consist of several modules, where some are developed outside the MEMO project.

As part of the MEMO 2nd generation terminals the MEMO-Cube is in a prototype stage and can be used as starting point for a product development, for DAB trials or as starting point for PC basis in mobile (e.g. automotive environments.).

The MEMO-Cube is the communication and pre-processing part of the 2nd generation terminal equipment managing the DAB and GSM networks. It is connected through a wireless LAN to a PC host (the application terminal) running the MEMO applications. It is a system for mobile trials. Therefore, no moving parts are used. The temperature should not exceed the range of 0 to +40 degrees Celsius. The humidity should be less than 70% without condense.

HARDWARE COMPONENTS OF THE MEMO-CUBE.
The Cube is based on the modularity of the PC/104 system. See PC/104 specification for more details. It consists of the modules listed:

-CPU-Module: AMD 5x86-133MHz processor, 20 Mbytes DRAM, 10 Mbytes solid state flash disk, 2 serial ports, 1 parallel port, floppy port.
-PC-Card-Module: 2 slots for Type-II PC-Cards.
-DC/DC-Converter: power supply for the MEMO-Cube, including Battery charger and power management.
-Accumulator.
-DABMOS-Card: Interface-Card to adapt the DABMOS to the PC/104 interface.
-SFC-Interface: This module converts the Simple-Full-Capacity-Output (SFCO) of the DABMOS to the PC/104 interface. The supported data rate is up to 1.7 MBit per second (DAB-Full stream).
-wLAN: Wireless LAN interface complying with the PC Card standard.
-GSM-modem: Modem for GSM connection.
-Housing: Covering the above listed components.

CAPABILITIES AND PERFORMANCE
The supported data rate is up to 1.7 Mbit per second (DAB-Full stream).

ACCESSORIES
Within a MEMO-Cube the following accessories are available
-GTI-flex DAB1 antenna for Band III and L-Band DAB reception.
-AC power adapter for 230V (output of about 12 V / 30 VA).
-GSM-Handy Bosch GSM-COM-607.

MECHANICAL DATA
-130 x 120 x 150 mm.

SOFTWARE COMPONENTS OF THE MEMO-CUBE.

overview:

The Cube Software runs with the Operating System LINUX. This software consist of several modules.

Modules designed outside the MEMO Project.
The following modules were designed outside the MEMO Project:

-Dual Ported RAM Interface. This module supplies the control over the DABMOS. It reads the FIC data via the Dual Ported RAM and performs functionality like tuning and sub-channel selection.

-FIC: This module decodes the information about the current Ensemble from the FIC and stores it into the Data Base.

-Data Base. The Data Base contains the information about the current Ensemble.

-Radio Manager. The Radio Manager performs the necessary handling while tuning and sub-channel selection.

-Control API. In order to control the modules which where designed outside the MEMO project the control API is used.

-PMD (Packet Mode Decoder). The PMD decodes the Packed Mode Data and sends the DG (Data Group) to the Notebook via a TCP/IP connection. The MOT Decoder runs on the Notebook due to performance reasons.

Modules designed by the MEMO Project.
The following modules were designed by MEMO Project:

-Inter Controller. The main part of the software is realised in the Inter Controller. The Inter Controller receives messages from the Notebook via the TCP/IP connection and reacts on them. These messages are formed in the MEMO message protocol. The command set is used by the communication protocol between the MEMO control program on the Notebook and the MEMO-CUBE.

The MEMO message protocol-atoms:
-Integer: an unsigned value of 4 bytes in Internet byte order.
-Visible string: a sequence of printable ANSI-characters, preceded by an Integer for length coding.
-Octet string: a sequence of bytes, preceded by an Integer for length coding.

There are four structures in the protocol:
-Compound statement: a sequence of a field identifier (type: Integer) and one of atom, sequence, choice or set.
-Sequence: a sequence of Compound statements.
-Choice: one Compound statement.
-Set: a sequence of count (type: Integer) and count x compound statement.

SFCI (Simple Full Capacity Interface Driver). This is a low level driver. The driver reads the data from the SFC-Interface card. Then it sends the data to the PMD or Stream Audio Video module.
