30 | | The MVME5500 provides more than just faster processor performance; it provides |
31 | | balanced performance from the processor, memory, local buses, and I/O subsystems. |
32 | | The powerful Marvell Discovery system controller, with support for a 133 MHz host bus |
33 | | and a 133 MHz SDRAM memory bus, is well matched to the high-speed processor. To |
34 | | match the system I/O to the outstanding processor performance, the MVME5500 |
35 | | provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting |
36 | | cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector |
37 | | are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment, so that both |
38 | | PMC sites are capable of 66 MHz operation. The MVME5500 also offers a Gigabit |
39 | | Ethernet interface, a 10/100BaseTX Ethernet interface, and two serial ports. All of this |
40 | | adds up to a set of well-balanced, high-performance subsystems for unparalleled |
41 | | performance. |

| 30 | The MOTLoad firmware package serves as a board power-up and |
| 31 | initialization package, as well as a vehicle from which user applications |
| 32 | can be booted. A secondary function of the MOTLoad firmware is to serve |
| 33 | in some respects as a test suite providing individual tests for certain |
| 34 | devices. |
| 35 | MOTLoad is controlled through an easy-to-use, UNIX-like, command line |
| 36 | interface. The MOTLoad software package is similar to many end-user |
| 37 | applications designed for the embedded market, such as the real time |
| 38 | operating systems currently available. |
| 39 | Refer to the MOTLoad Firmware Package User’s Manual, listed in |
| 40 | Appendix D, Related Documentation, for more details. |
