产品描述

GRBTU 3BSE013175R1 ABB底座模块可用于ABB生产的各种工控机器人系统中，作为机器人控制器的基础部件。

GRBTU 3BSE013175R1标准PC/AT架构定义了两种不同类型的地址空间，用于CPU板上的设备和外围设备。这些空间通常是命名内存地址空间和输入/输出地址空间。这些区域的边界仅限于物理上位于CPU上的地址总线的数量板VMIVME-7698在板上有32条地址总线，因此将地址空间的限制定义为4 GB。

标准PC/AT架构定义从0到4 GB的内存地址空间和单独的输入/输出地址从零到64 KB的空间。VMIVME-7698上的ISA设备由BIOS在启动和遵守标准PC/AT架构。它们映射到输入/输出地址空间在标准地址内，其中断被映射到标准中断控制寄存器。然而，除实时设备外，所有ISA设备时钟、键盘和可编程定时器几乎可以重新定位到输入/输出地址空间的标准1 KB。表D-1定义了可用于ISA设备重新配置的地址。如前所述，在标准PC/AT系统中，所有输入/输出设备都映射到输入/输出地址空间。然而，在VMIVME-7698上，动态随机访问内存（DRAM）、电池供电的SRAM和看门狗定时器在内存地址空间。BIOS将DRAM放置在地址零处，并扩展到车载DRAM的物理限制。

Product description

The GRBTU 3BSE013175R1 ABB base module can be used in various industrial robot systems produced by ABB as a basic component of the robot controller.

The GRBTU 3BSE013175R1 standard PC/AT architecture defines two different types of address Spaces for devices and peripherals on the CPU board. These Spaces are usually named memory address Spaces and input/output address Spaces. The boundaries of these areas are limited to the number of address buses physically located on the CPU. The board VMIVME-7698 has 32 address buses on the board, thus defining the limit of address space to 4 GB.

The standard PC/AT architecture defines memory address Spaces from 0 to 4 GB and separate input/output addresses from zero to 64 KB. The ISA device on the VMIVME-7698 is booted by the BIOS and complies with the standard PC/AT architecture. They map to the input/output address space within the standard address, where the interrupt is mapped to the standard interrupt control register. However, with the exception of real-time devices, all ISA device clocks, keyboards, and programmable timers can be repositioned almost to the standard 1 KB of the input/output address space. Table D-1 defines the addresses that can be used for ISA device reconfiguration. As mentioned earlier, in a standard PC/AT system, all input/output devices are mapped to the input/output address space. However, on the VMIVME-7698, dynamic random access memory (DRAM), battery-powered SRAM, and watchdog timers are in the memory address space. The BIOS places the DRAM at address zero and extends to the physical limits of on-board DRAM.
