This board is a sophisticated VME bus single board computer (6U size, 1 slot width) equipped with MC7448 processor (PowerPC G4), Tsi108 (system controller) and Tsi148 (PCI-VME bridge). The CPU clock frequency (MC7448) is 1GHz or 1.4GHz and it has a built-in L1 cache (64k bytes) and L2 cache (1MB). It supports automatic slot type recognition. It can be used as a single central CPU, but additional CPU boards can also be added depending on the processing load.
Memory
It is equipped with DDR-SDRAM main memory, and supports CPU power and I/O power with the powerful bandwidth (3.2GB/ sec). Memory capacity is 512MB or 1GB, and in either case, single-bit data errors support correctable ECC. It has both high efficiency and high reliability.
Other interfaces
It is equipped with a RS232C serial port (1 ch) and Gigabit Ethernet (2 ch) as front panel I/O, as well as an onboard CompactFlash socket and 2 onboard PMC (PCI/PCI-X) slots.
The board’s VME interface supports VME64x and 2eSST, and it can be used either the system slot or non-system slot of the VME bus.
