FPGA VME Bridge Replacement for End of Life Tsi148

X-ES Has Your Solution to the End of Life (EOL) Tsi148 VME Bridge

6U VME products with an integrated Xilinx Artix-7 FPGA VME Bridge designed to be pin-compatible with the Radstone/GE/Abaco PPC7D VME IDT Tsi148-based card, providing users with a straightforward, disruption-free upgrade path for legacy systems.

Future-Proofing VME Systems

X-ES selects an FPGA-based VME solution enabling high performance VMEBus capability on our flagship SBCs. Offering a wide variety of valuable features beyond what the Tsi148 VME Bridge had been capable of, the Xilinx Artix-7 VME Bridge supports a x4 PCI Express Gen2 to the host interface and supports an external DDR3 SDRAM DMA buffer.

With its firmware upgradeable design and support for future portability of IP to a new chip, X-ES VME boards offer system integrators a VME Bridge solution devoid of components subject to lifecycle concerns, in an even smaller chip package than had previously been available.

An Evolution & Extension Beyond the Tsi148

1981

VMEBus32 protocol introduced, with BLT transfer at 40 MB/s, connecting the processing subsystem with VMEBus.

1987-2003

VMEBus protocol continues to grow and develop, most recently supporting 2eSST transfer at 320 MB/s on a 5-row connector.

2015

Production of the IDT Tsi148 VME Bridge ceases, rendering the majority of the industry’s current VME products obsolete.

2016

X-ES chooses the Xilinx Artix-7 FPGA-based VME Bridge as the feature-rich technology to continue our VME products.

A History of VMEBus Technology

The VMEBus form factor has been a fundamental building block of high-end embedded computing systems for more than 30 years, stretching back to the introduction of the VMEBus32 protocol in 1981.

A desire to connect non-68000 series processing boards, such as PPC and x86 processing subsystems which do not natively support the 68000-style connector, required a bridge chip to connect PCI to the VMEBus.

PCI to VME Bridge chips were thus built to allow processing subsystems to access the VMEBus. Tundra (IDT) introduced the Universe II in 1997, which supported PCI-to-VME64. In 2004, Tundra/IDT began selling the Tsi148 VME Bridge, which supported PCI-X-to-VME64/VME320. The Tsi148 quickly became a standard component in many of the embedded computing industry’s VME boards.

A Look Into the Future of VME

In 2009, Tundra was acquired by IDT; the Tsi148 VME Bridge continued to be manufactured at IBM’s Essex Junction fabrication facility.

Five years later, IBM decided to exit the semiconductor chip manufacturing business, citing lack of financial feasibility. The fate of the industry’s main VME Bridge was sealed, with the Tsi148’s EOL announcement in 2014.

X-ES is committed to VME and the many systems that rely upon its proven technology. With our cutting-edge FPGA-based VME Bridge, X-ES is able to offer more features and functionality than had ever previously been available with a traditional VME Bridge. Our Intel® and NXP 6U VME SBCs come standard with high-performance processing capabilites, a wide variety of I/O support including Ethernet, USB, and serial, and are backed by our top-tier team of engineers.
