带专用微处理器的智能型仪器的研制正日益受到人们的重视。因为,与利用通用微机开发的智能仪器相比,它在硬件成本上有明显的优势。专用微处理器系统的硬件一般较为简单,甚至可以是一个最小系统。必要时,亦可直接利用诸如T P—801这一类廉价而又易于扩展的单板机作为硬件设计的基础。然而,微处理器系统能直接提供的数值运算功能很有限,使得这类系统的软件开发周期比直接利用通用微机系统要长得多,尤其是在一些要求提供较强的数据处理功能的场合,这一弱点表现尤为明显。这在很大程度上限制了专用智能型仪器数据处理性能的提高。
The development of intelligent instruments with special microprocessors is gaining more and more attention. Because, compared with intelligent instruments developed using a general-purpose microcomputer, it has significant advantages in terms of hardware costs. Dedicated microprocessor system hardware is generally relatively simple, and can even be a minimum system. When necessary, direct access to a single, inexpensive and easily expandable single board computer such as the T-801 can also be used as a basis for hardware design. However, the numerical functions provided by the microprocessor system are limited, which makes the software development cycle of such systems much longer than the direct use of general-purpose microcomputer systems. Especially in some occasions where strong data processing functions are required, This weakness is particularly evident. This largely limits the dedicated intelligent instrument data processing performance.
