LEON processor in focus at DASIA 2006 conference in Berlin
The international space system engineering conference DASIA 2006 (DAta
Systems In Aerospace) was held this year in May in Berlin, Germany. At
the conference, the LEON processor was presented in more than ten
A complete panel session was dedicated to the LEON processor, during
which Gaisler Research presented a wide range of applications in which
the LEON processor is being used, ranging from future 1000 MIPS
multiprocessing systems, via dedicated microcontrollers, to radiation
- This conference confirms Gaisler Research's position as the
leading supplier of high performance processor IP solutions to the
space industry, says Per Danielsson the CEO of Gaisler Research AB.
Special LEON panel session
European Space Agency (ESA) presented the Giga INstruction Architecture
(GINA) for the future ESA microprocessor based on the LEON3-FT IP core.
The presentation covered the complete series of the SPARC based
processors used by ESA, including LEON2 and the new LEON3-FT IP core
from Gaisler Research.
Gaisler Research presented the detailed implementation of the
multi-core processor based on the LEON3-FT IP core. This new
LEON3-FT-MP system contains four LEON3-FT processors and a set of
additional IP cores such as SpaceWire, Ethernet, CAN and PCI. The
presentation covered the validation of the system using a Xilinx
Virtex-4 FPGA development board. The software based validation covered
symmetric multi-processing (SMP) using the eCos real-time operating
system and message passing through shared memory using RTEMS.
Gaisler Research presented the results from the SEU test campaign for
the LEON3-FT-RTAX processor. The LEON3-FT-RTAX is implemented using a
radiation-tolerant FPGA from Actel Corporation. The results show that
the fault-tolerance features included in the LEON3-FT-RTAX processor
are well adapted to mitigate the SEU effect encountered in the space
environment and provide a fault-free processing platform for both
payload and platform applications.
Gaisler Research presented the SpaceWire Remote Terminal Controller
(RTC) ASIC that is developed jointly with Saab Ericsson Space, Sweden.
The SpaceWire-RTC ASIC is based on the GRLIB IP core library and the
LEON2-FT VHDL model. The ASIC features SpaceWire and CAN bus
interfaces, and will be manufactured on a 0,18 um radiation hardened
Alcatel Alenia Space, Italy, presented their OMNIA ASIC development.
The OMNIA ASIC is a SoC design based on LEON2-FT which has been
enhanced with the GRFPU-FT High-Performance Floating-Point Unit
developed by Gaisler Research.
Saab Ericsson Space, Sweden, presented their COLE ASIC development. The
COLE ASIC is also a SoC design based on LEON2-FT. It includes the
GRFPU-FT High-Performance Floating-Point Unit and the Memory Management
Unit (MMU), both developed by Gaisler Research.
Swedish Space Corporation, Sweden, presented the on-board data handling
system for the PRISMA rendezvous and formation flying mission. The
system controller is based on the LEON3-FT fault tolerant processor
implemented in an Actel FPGA.
Atmel Corporation, France, presented the development timeline for the
AT697 processor which is based on the LEON2-FT processor core.
Verhaert Space, Belgium, presented their Advanced Data and Power
Management System (ADPMS) which is based on the AT697 LEON2-FT
processor. ADPMS is planned for in-orbit demonstration next year on
ESA's PROBA-II technology demonstration satellite mission. In addition
to performing the initial system studies and trade-offs, Gaisler
Research has developed the telemetry and telecommand FPGA used in ADPMS.
IDA Technical University Braunschweig, Germany, presented the Venus
Express Monitoring Camera (VMC) which uses the LEON2 processor core.
The camera control
is implemented in an FPGA and integrates in, addition to the processor,
peripheral control logic and interfaces to various sensors and
VEGA IT GmbH, Germany, presented their Generic Emulator Test System
(GETS) project, in which the TSIM instruction simulator from Gaisler
Research has been
The conference is organised by EUROSPACE, an
association of the European space industry, in co-operation with the
European Space Agency (ESA), among others.
