Vibro-meter VM600 XMV16振动状态监控模块VM600的高质量、高可靠性状态监控模块Mk2/VM600机架式机械监控系统–针对高性能振动监控应用进行了优化。XMV16振动状态监控模块提供16个动态通道和4个转速计(速度)通道，所有通道均可独立配置。XMV16处理模块始终与相关的XIO16T输入/输出模块一起作为一组模块(卡对)使用。特征：16个动态通道和4个转速通道每个动态通道和每个双通道最多20个处理输出(每个xmv 16 12个)利用异步(固定频率)或同步(顺序跟踪)采样在所有通道上同时采集数据24位数据采集，高信噪比数据处理，高分辨率FFT高达每500 ms 6400行。专为与VibroSight软件配合使用而设计具有更大字长的CPU需要更多的电路，因此物理上更大，成本更高，消耗更多的功率(因此产生更多的热量)。

因此，更小的4位或8位微控制器即使有更大字长(如16位、32位、64位甚至128位)的CPU可用，也普遍用于现代应用中。然而，当需要更高的性能时，更大的字长(更大的数据范围和地址空间)可能会利大于弊。CPU可以具有比字长更短的内部数据路径，以减小尺寸和成本。例如，即使IBM系统/360 指令组是一个32位指令集，System/360型号30和型号40在算术逻辑单元中有8位数据路径，因此32位加法运算需要四个周期，每8位操作数一个周期，即使摩托罗拉68000系列指令集是一个32位指令集摩托罗拉68000和摩托罗拉68010在算术逻辑单元中有16位数据路径，因此32位加法需要两个周期。

为了获得较低和较高位长提供的一些优点，许多指令集对于整数和浮点数据具有不同位宽，允许实现指令集的CPU对于设备的不同部分具有不同的位宽。例如，IBM系统/360指令集主要是32位，但支持64位浮点值，以提高浮点数的准确性和范围。[30]System/360 Model 65有一个用于十进制和定点二进制运算的8位加法器和一个用于浮点运算的60位加法器。[69]许多后来的CPU设计使用类似的混合位宽，特别是当处理器是用于通用用途，需要整数和浮点功能的合理平衡时。

Vibro-meter VM600 XMV16 vibration status monitoring module The high-quality and highly reliable status monitoring module of VM600, Mk2/VM600 rack mounted mechanical monitoring system, has been optimized for high-performance vibration monitoring applications. The XMV16 vibration status monitoring module provides 16 dynamic channels and 4 tachometer (speed) channels, all of which can be independently configured. The XMV16 processing module is always used as a set of modules (card pairs) along with the relevant XIO16T input/output modules. Features: 16 dynamic channels and 4 speed channels. Each dynamic channel and each dual channel can have up to 20 processing outputs (16 12 per xmv). Asynchronous (fixed frequency) or synchronous (sequential tracking) sampling is used to simultaneously collect data on all channels, with 24 bit data collection, high signal-to-noise ratio data processing, and high-resolution FFT of up to 6400 lines per 500 ms. Designed specifically for use with VibroSight software, CPUs with larger word lengths require more circuits, which are physically larger, more expensive, and consume more power (thus generating more heat).

Therefore, smaller 4-bit or 8-bit microcontrollers are commonly used in modern applications, even if CPUs with larger word lengths (such as 16 bit, 32 bit, 64 bit, or even 128 bit) are available. However, when higher performance is required, a larger word length (larger data range and address space) may have more advantages than disadvantages. The CPU can have an internal data path that is shorter than the word length to reduce size and cost. For example, even if the IBM System/360 instruction set is a 32-bit instruction set, System/360 models 30 and 40 have 8-bit data paths in the arithmetic logic unit, so 32-bit addition operations require four cycles, one cycle per 8-bit operand. Even if the Motorola 68000 series instruction set is a 32-bit instruction set, Motorola 68000 and Motorola 68010 have 16-bit data paths in the arithmetic logic unit, so 32-bit addition requires two cycles.

In order to achieve some of the advantages provided by lower and higher bit lengths, many instruction sets have different bit widths for integer and floating-point data, allowing CPUs that implement instruction sets to have different bit widths for different parts of the device. For example, the IBM system/360 instruction set is mainly 32-bit, but supports 64-bit floating-point values to improve the accuracy and range of floating-point numbers. The System/360 Model 65 has an 8-bit adder for decimal and fixed-point binary operations and a 60-bit adder for floating-point operations. Many later CPU designs used similar mixed bit widths, especially when processors were designed for general purposes and required a reasonable balance of integer and floating-point functions.
