Stackable Computer Architecture Moves to 3rd Generation

Change is a concept that is well known in the computer industry. Designers and manufacturers alike have embraced this trend in an ongoing race to increase computing power while reducing size, weight, and power and cost (SWaPaC). With the latest round of ultra-low power processors from Intel, VIA, AMD and DMP, stackable computer systems need to adapt as well, especially with respect to I/O, while striking a balance between new and legacy technology.

Small Form Factor Computing in OpenVPX

The new OpenVPX™ (VITA 65) standard helps military system designers build compatible embedded systems by defining “profiles” to which vendors can adhere when designing boards, and system integrators can use to locate available COTS solutions. The market is seeing a proliferation of 6U VPX boards, which have numerous interconnect pins and are able to support many more simultaneous external connections with a single profile. In comparison, 3U VPX boards have fewer interconnect pins available, resulting in a far wider fragmentation of profile support, since vendors can support fewer external connections with a single 3U card profile. That makes it all the more important for designers of small form factor VPX systems to understand how to effectively use OpenVPX profiles.

Using FPGAs to Improve x86 Processor I/O Flexibility

By offering the ability to update application functionality, provide a reconfigurable solution and enable easy design customization, Field Programmable Gate Array (FPGA) technology has long been known as a cost-effective design resource. Similarly, x86 processor architectures share many of the same extended ecosystem, installed base, and multi-functionality benefits as FPGAs.

Architectures for Cognitive Systems

A need exists for small, autonomic systems in the battlefield. Autonomy allows the creation of unmanned systems to perform complex, high-risk, and/or covert operations in the battlefield without the need for constant human operation. Current computing systems are not optimized to perform intelligent operations such as environmental awareness, learning, and autonomic decisions in a size, weight, and power form factor that matches platforms envisioned for future use.

Circuit-Switched Memory Access in Photonic Interconnection Networks for High-Performance Embedded Computing

High-performance embedded systems, such as those found in aerial surveillance platforms and handheld devices used by the military, are of key importance. These systems are characterized by stringent power budgets and the need for extremely fast, streaming access to memory. While general-purpose processors offer a customizable solution, they typically do not meet the power and performance requirements for the systems in question. For this reason, specialized chip multiprocessors (CMPs) are used.

Analysis of Voltage and Current Signal Processing in a Li-ion Battery Management System

A Battery Management System (BMS) manages Li-ion batteries in a storage system for pulsed power weapons aboard Naval vessels. The system charges the batteries with a buck converter according to the Constant Current Constant Voltage method. The BMS uses analog equipment to measure signals and then digitally converts signals for transmittal to a Field Programmable Gate Array (FPGA).

Machine Control Interface Module

Trio Motion Technology (Tewkesbury, UK) has added to its MC464 Motion Coordinator machine controller range with the launch of its new EtherCAT Master drive interface module. The new module provides tightly synchronized control for up to 64 slave axes on the MC464 — up to seven modules may be added, each providing eight 100 nanosecond registration inputs which can be mapped to any axis. Trio’s MC464 Motion Coordinator is based on the 64-bit 400MHz MIPS processor with 64-bit position registers and double floating point maths for exceptional servo precision. With multitasking TrioBASIC programming, the central control unit includes analogue and digital I/O, status display, SD card memory expansion, axis synchronization and programming ports with a wide choice of half-and full-height expansion modules for drive technology, I/O expansion, factory and fieldbus communication.

Stand-Alone Real-Time Clock/Calendar

Microchip Technology (Chandler, AZ) recently announced its first stand-alone I2CTM Real-Time Clock/Calendar (RTCC) family. All six MCP794XX devices are highly integrated at a low cost, including ample amounts of on-chip EEPROM and SRAM, as well as a user-lockable section of EEPROM available for a 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. The devices include digital trimming for time-of-day calibration, and a battery-switchover feature that supports backup power at very low voltage and current levels.
