Product Family Overview

National Instruments AT-MXI MXIbus ISA Interface Card

Features
  • Supports 32-Bit (A32), 24-Bit (A24) and 16-Bit (A16) Addressing
  • Supports Both 16-Bit (D16) and 8-Bit (D08) Data Transfers
  • Conforms to ISA Specification
  • Conforms to the MXIbus Specification

Description

The AT-MXI can function as both a MXIbus master and a MXIbus slave. When operating as a MXIbus master, the AT-MXI converts PC AT memory cycles initiated by the CPU or an alternate bus master on the PC AT bus into MXIbus cycles intended for a MXIbus slave device. When operating as a MXIbus slave, the AT-MXI converts MXIbus cycles initiated by a MXIbus master into PC AT memory or I/O bus cycles so that other MXIbus devices can freely access (share) resources within the PC AT.

As a MXIbus master, the AT-MXI supports 32-bit (A32), 24-bit (A24) and 16-bit (A16) addressing. As a MXIbus slave, the AT-MXI supports A24 addressing to PC AT memory and A16 addressing to the AT-MXI communication registers and to the PC AT I/O space. The AT-MXI supports both 16-bit (D16) and 8-bit (D08) data transfers while operating as either a MXIbus master or a MXIbus slave. The AT-MXI cannot support 32-bit (D32) data transfers because the PC AT data bus is only 16 bits wide.

Because the AT-MXI uses the same communication register set that is used by VXIbus Message-Based devices, other MXIbus devices can view the AT-MXI as a VXIbus device. The following are some of the numerous benefits that can result from using the VXIbus register architecture:

• Dynamic device identification and configuration during system initialization
• Standardized Word Serial communication between devices
• Dynamic resource (memory) allocation
• Message (signal) passing protocols between devices
• Shared memory architectures

The AT-MXI supports MXIbus block-mode transfers while operating as either a MXIbus master or a MXIbus slave. With block-mode transfers, data located in consecutive memory locations can be transferred at higher rates because MXIbus addressing information is not sent with each data transfer. The AT-MXI supports the use of the direct memory access (DMA) controller on the PC AT computer when transferring block-mode data between the PC AT bus and the MXIbus. Optionally, any MXIbus or PC AT bus master can be used to initiate and transfer block-mode data via the AT-MXI.

In addition to these features, the AT-MXI is also able to function as the MXIbus System Controller and can terminate the MXIbus signals directly on the AT-MXI interface board. The AT-MXI also supports the MXIbus arbitration lock and fairness options.
