EMERSON KJ3001X1-CA1涡流传感器前置器
USB主机控制器通过处理和调度数据结构在系统存储器和USB之间移动数据。控制器执行计划列表，并向系统报告状态。注意：VMIVME-7750的默认CMOS设置禁用USB功能。这为实时系统提供了更多的中断和更少的中断延迟。如果启用了USB，用户必须知道中断共享和延迟将受到影响。VMIC的VMIVME-7750具有超出典型台式计算机系统的其他功能。该单元提供四个软件控制的通用计时器以及一个可编程看门狗计时器，用于同步和控制嵌入式应用程序中的多个事件。VMIVME-7750还提供了可启动的闪存系统和32 KB的非易失性SRAM。此外，VMIVME-7750支持嵌入式智能VME网桥，以允许与最苛刻的VME应用程序兼容。这些特性使该装置成为嵌入式应用的理想选择，特别是在无法使用标准硬盘驱动器和软盘驱动器的情况下。VMIVME-7750还通过集成这些功能的专用电路来支持I2C。
The USB Host Controller moves data between system memory and the USB by
processing and scheduling data structures. The controller executes the scheduled lists,
and reports status back to the system.
NOTE: Default CMOS settings of the VMIVME-7750 have USB functions disabled.
This allows more interrupts and less Interrupt Latency for Real Time system. If USB is
enabled, the user must be aware that Interrupt Sharing and Latency will be effected.VMIC’s VMIVME-7750 features additional capabilities beyond those of a typical
desktop computer system. The unit provides four software-controlled,
general-purpose timers along with a programmable Watchdog Timer for
synchronizing and controlling multiple events in embedded applications. The
VMIVME-7750 also provides a bootable Flash Disk system and 32 Kbyte of
non-volatile SRAM. Also, the VMIVME-7750 supports an embedded intelligent VME
bridge to allow compatibility with the most demanding VME applications. These
features make the unit ideal for embedded applications, particularly where standard
hard drives and floppy disk drives cannot be used. The VMIVME-7750 also supports
I
2C by integrating specialized circuitry for these functions.
