The Abaco Systems VG5 7457 is a 6U VMEbus single-board computer built around dual MPC7457 PowerPC processors with AltiVec technology, delivering processing speeds from 867 MHz to 1.267 GHz. Each processor node includes 2 MB L3 cache, 64 KB L1 cache, and 256/512 KB on-die L2 cache, paired with up to 512 MB of ECC-protected DDR SDRAM and 256 MB of high-speed Flash memory per node. The board integrates comprehensive I/O: two Gigabit Ethernet ports (10/100/1000 Mb), two Fast Ethernet ports (10/100 Mb), six serial I/O ports including four high-speed multi-protocol controllers supporting 10 Mbit operation, one SATA interface, and up to 32 GPIO lines (LVTTL). Two PMC expansion slots support custom mezzanine modules, with one slot dedicated to the onboard VME bridge and SATA interface. Additional features include a user-programmable FPGA, eight 32-bit timer/counters, eight DMA channels, real-time clock, watchdogs, and temperature monitoring. The Tundra Universe IID VMEbus interface provides VME64 connectivity per IEEE Std. 1101.2-1992 and ANSI/VITA 20-2001, with VITA 30.1-2001 compliance. Available in commercial air-cooled or conduction-cooled variants, the board measures 233 × 160 × 20.32 mm and occupies a single 6U slot, making it suitable for both standard industrial and thermally demanding embedded environments requiring high-performance real-time processing and signal processing capabilities.
