ALTHEA 7910
PCI Express to VME64x Transparent Bridge Data Sheet
Overview
IOxOS Technologies is releasing the ALTHEA 7910 solution, a PCI Express x4
GEN1/GEN2 to VME64x transparent bridge embedding a DMA engine that
works with on-chip memory and an optional DDR3 external device.
This solution provides a full VME64x Master/Slave interface with Slot-1
functions and interrupt management with a direct bridge to a PCI Express
upstream port, assuring an extremely low latency combined with a high
data bandwidth. Advanced VME64x data transport 2eVME and 2eSST
modes, including broadcast, are natively supported with maximal burst
length capability. Large data-transaction buffers guarantee maximal 2eSST
data transfer support for continuous operation. A key element for this high
performance is an embedded dual channel Intelligent DMA Controller
(IDMAC), which allows high bandwidth simultaneous Read/Write
transactions exceeding 1'600 MBytes/s data rates with PCI Express GEN2.
The full solution is delivered as an encrypted binary file targeting a Xilinx Artix-
7 device (XC7A75T in FGG484 package). The result is a low cost and low
power single chip solution which provides higher performance in comparison
with existing VME interfaces, a faster integration process and a robust
obsolescence management strategy. The implementation, which is done
entirely in VHDL, guarantees its portability to coming generations of FPGA
devices, significantly extending the operational life of the solution.
The PCI Express to VME64x bridge core function has been successfully
implemented and validated in all IOxOS Technologies' VME Single Board
Computers since 2009, leveraging Intel x86 (Xeon, i5/i7), AMD (Opteron) and
PowerPC (QorIQ P and T series) platforms running under Windows XP/7, Linux
and VxWorks. This widespread deployment allows the ALTHEA 7910 solution
to reach the high maturity and reliability levels required by the Mil/Aero,
Transport and High Energy Physics (HEP) applications where these COTS
have been installed.
Due to its long and proven experience in VME design, IOxOS Technologies
provides an active support to guide the end user throughout the integration
process, considering the customization of the solution upon request.
