什么比第一台计算机ENIAC的计算能力更强，并且3.2 x 10-5更小？
采用非常小的3½“x3½”封装，具有安全的Intel®Atom™处理器的处理能力，扩展的工作温度为-40°C至85°C，可接受来自的输入电压范围
8到30 VDC？
EAI型号TR-20台式模拟计算机于1963年发布
单板计算机（SBC）Raven来自VersaLogic。
Raven实际上是一个由三个SBC组成的系列，它们采用Quad（E3845），Dual（E3827）和Single（E3815）核心“Bay Trail”处理器。
让我们仔细看看VersaLogic以及是什么让他们的Raven主板如此惊人。
现在大多数人都不认识VersaLogic的名字，因此他们认为他们是一些新的车库公司。
是的，VersaLogic开始在一个车库，但那是大约40年前。
他们是一家总部位于俄勒冈州的公司，专门研究具有强大计算能力的坚固耐用的SBC。
他们的电路板是长期制造的，具有较长的寿命，在SBC市场非常不典型。
来自他们的网站：“我们有一个正式的生命周期管理计划，以维持产品从摇篮到坟墓，并备份新推出的产品，并提供5年保修。”
让我们更仔细地看看Raven SBC家族及其能做些什么。
Raven的核心和力量来自英特尔的E3800处理器系列。
该系列有四核，双核和单核选项。
英特尔是全球处理器领域的领导者，他们的网站上有关于E3800系列的信息：“英特尔®凌动™处理器E3800产品系列是第一款专为智能系统设计的片上系统（SoC），提供出色的计算，图形化，
在扩展的热条件下运行时的介质和介质性能。
这些SoC基于Silvermont微架构，利用英特尔业界领先的22纳米工艺技术和3-D三栅极晶体管，显着提高了计算性能和能效。“
Raven有一个安全系统，称为可信平台模块（TPM）。
它是做什么的，坦率地说，为什么我们应该关心？
TPM是当今许多SBC应用程序所需的一种安全系统。
微软对TPM的解释有很好的解释。
“TPM是一种微芯片，旨在提供基本的安全相关功能，主要涉及加密密钥。
TPM通常安装在计算机或笔记本电脑的主板上，并使用硬件总线与系统的其余部分进行通信。“这对您和我来说意味着什么？
这意味着TPM将提供基本的安全相关功能，这对于工业物联网（IIoT）至关重要。
英飞凌科技公司的史蒂夫汉纳表示，“为了实现和加速工业物联网（IIoT）的目标，工业互联网联盟（IIC）已将安全性放在必须做的清单上。
该联盟的2016年9月工业互联网安全框架（IISF）提供了一个解决IIoT系统安全问题的通用安全框架。
可信平台模块（TPM）在该文档中作为关键技术突出显示。

Raven主板采用紧凑的3½“x3½”（95 mm x 95 mm）封装，只有两个迷你PCIe插槽。
这允许系统包括用于固态程序和数据存储的mSATA驱动器，以及添加用于通信的Wi-Fi模块（或用于定位服务的GPS模块）。
坚固耐用的（MIL-STD-202G）电路板可支持-40°C至85°C的工作温度。
电源输入可支持8至30 VDC的电压范围。
为什么需要这么宽的输入范围？
我真的不知道，所以我回到VersaLogic了解。
VersaLogic产品经理Kerry Howell说：
“我们的客户支持团队得到的最大问题是电力。
这就是为什么我们选择宽输入电压范围（8到30 VDC），以便我们可以容纳固定和移动12和24伏系统。
我们还可以防止移动电源系统（车辆）中常见的瞬态电压。“

因此，如果您正在寻找功率大，体积小，坚固耐用的单板计算机，那么Raven就是您的最佳选择。
凭借三种核心选项和市场上最宽的输入电压范围，Raven将成为物联网以及自动化，运输，防御，模拟和视觉等垂直市场的理想选择。

What has more computing power than one of first computers, the ENIAC, and is 3.2 x 10-5 smaller? What comes in a very small 3 ½” x 3 ½” package, has the processing power of an Intel® Atom™ processor with security, an extended operating temperature of -40°C to 85°C and can accept an input voltage range from 8 to 30 VDC?

The Single Board Computer (SBC) Raven is from VersaLogic. The Raven is actually a family of three SBCs that come in Quad (E3845), Dual (E3827), and Single (E3815) core “Bay Trail” processors. Let’s take a closer look at VersaLogic and what makes their Raven boards so amazing.
Now most people don’t recognize the name of VersaLogic, so they assume that they are some new garage-based company. Yes, VersaLogic started in a garage, but that was about 40 years ago. They are an Oregon-based company that specializes in ruggedized SBCs with some serious computing power. Their boards are built for the long haul with long life spans which is very atypical in the SBC market. From their website: “We have a formal life cycle stewardship program to sustain product from cradle to grave and back up newly introduced products with a 5-year guarantee.”
Let’s look more closely at the Raven SBC family and what it can do. The heart and power of the Raven comes from Intel’s E3800 processor family. There are Quad, Dual, and Single core options for this family. Intel, the world’s leader in processors, has this on their website about the E3800 family: “The Intel® Atom™ processor E3800 product family is the first system-on-chip (SoC) designed for intelligent systems, delivering outstanding compute, graphical, and media performance while operating in an extended range of thermal conditions. These SoCs are based on the Silvermont microarchitecture, utilizing Intel’s industry-leading 22 nm process technology with 3-D tri-gate transistors, which deliver significant improvements in computational performance and energy efficiency.“
The Raven has a security system that is known as Trusted Platform Module (TPM). What does it do, and, frankly, why we should care? TPM is a type of security system that is required in many SBC applications today. Microsoft has a great explanation of what TPM is. “A TPM is a microchip designed to provide basic security-related functions, primarily involving encryption keys. The TPM is usually installed on the mother board of a computer or laptop, and communicates with the rest of the system using a hardware bus.” What does this mean for you and me? It means that the TPM will provide basic security-related functions which is essential for the Industrial Internet of Things (IIoT). According to Steve Hanna at Infineon Technologies, “With the goal of enabling and accelerating the industrial Internet of Things (IIoT), the Industrial Internet Consortium (IIC) has placed security high on its must-do list. The consortium’s September 2016 Industrial Internet Security Framework (IISF) provides a common security framework that addresses security issues in IIoT systems. Trusted Platform Module (TPM), is highlighted in that document as a key technology.

The Raven boards come in a compact 3 ½” x 3 ½” (95 mm by 95 mm) package that has not one but two mini PCIe sockets. This allows a system that includes an mSATA drive for solid state program and data storage as well as adding a Wi-Fi module for communications (or a GPS module for location services). The ruggedized (MIL-STD-202G) board can support operating temperatures of -40°C to 85°C. The power input can support voltage ranges from 8 to 30 VDC. Why the need for such a wide input range? I really did not know, so I went back to VersaLogic to find out. Kerry Howell, a VersaLogic product manager, said:
“The biggest issue that our customer support team gets calls about is power. That is why we went to the wide input voltage range (8 to 30 VDC) so that we can accommodate both fixed and mobile 12 and 24 volt systems. We also have protection from transient voltages that are often found in mobile power systems (vehicle).”
Check out the Product Training Module (PTM) on the Raven.
So if you are looking for a Single Board computer with big power and small size that is rugged and secure, look no further than the Raven. With three core options available and the widest input voltage range in the market, the Raven would be ideal for the Internet of Things as well as vertical markets of automation, transportation, defense, simulations and vision.
