Themis Computer USPIIe-USB

Introduction

Themis Computer's new USPIIe-USB™ is a family of high performance 6U VMEbus computer boards based on the Sun® Microsystems 500MHz and 650MHz 64-bit UltraSPARC® processors. The USPIIe-USB provides users with 500 MHz and 650 MHz UltraSPARC® RISC processor options. Themis offers a down-clocked variant of the 650-MHz UltraSPARC processor, to 600-MHz, for users who can accept a reduction in peak processing capacity in exchange for increases in thermal management and design margins. Themis' USPIIe-USB supports 64-bit Solaris™ 8 and Solaris 9 operating environments, enabling embedded computing users to access thousands of off-the shelf Solaris™ software solutions.

Designed for the highest level of configuration flexibility and performance, the USPIIe-USB integrates the Sun 64-bit 650MHz UltraSPARC® IIi processors with a local PCI bus (PMC) peripheral controller slot, and a high performance bridge. This high speed VME64 board is available in one-slot, two-slot and three-slot configurations that offer a wide range of I/O and performance options.

The cost-effective USPIIe-USB/1 is a single-slot configuration that has low power dissipation, and high flexibility for embedded computing applications. It features dual 80MB/sec Ultra2 LVD SCSI ports, one 10/100Base-T Ethernet port, and four RS-232 serial ports. Memory is expandable up to 2 GB using memory mezzanine cards. This baseboard configuration provides a 64-bit PMC slot for local I/O or graphics expansion. Further I/O expansion is available via a 64-bit PCI riser to the second and third VME slots.

The USPIIe-USB/2P2 two-slot configuration offers significant I/O expansion options, including two additional PMC slots. This expanded I/O configuration provides AC97 audio, a second 10/100Base-T Ethernet port, two multiprotocol serial ports and a software readable front panel rotary switch. These features make it ideal for data and telecommunications applications.

The USPIIe-USB/2P3 is a doublewide configuration providing users three additional PMC slots without the expansion features of the USPIIe-USB/2P2 configuration. All versions may be configured with Themis' high performance TGA3D graphics co-processor. The TGA3D uses one additional VMEbus slot and provides one additional PMC slot.
