- Page 17 This chapter briefly describes the board level hardware features of the MVME2600 series Single Board Computers. The chapter begins with a board level overview and features list. Memory maps are next, and are the major feature of this chapter.
- Page 18 Refer to Chapter 5 for Endian Issues, which covers which parts of the MVME2600 series use big-endian byte ordering, and which use small-endian byte ordering. The terms control bit and status bit are used extensively in this document.
- Page 19 Overview The MVME2600 series SBC family, hereafter sometimes referred to simply as the MVME2600 or the V2600 series, provides many standard features required by a computer system: SCSI, Ethernet interface, keyboard interface, mouse interface, sync and async serial ports, parallel port, boot Flash, and up to 256MB of ECC DRAM.
- Page 20 RESET/ABORT Switch Status LEDs System Block Diagram The MVME2600 series provides the 256KB look-aside external cache option. The Falcon chip set controls the boot Flash and the ECC DRAM. The Raven ASIC functions as the 64-bit PCI host bridge and the MPIC interrupt controller. PCI devices include: SCSI, VME, Ethernet, and one PMC slot.
