A DMA link and a Qbus I/O-mapped interface to connect the microVAX with the VMEbus

  • 1. Istituto Nazionale di Fisica Nucleare, Bologna (Italy)

Description

A connection between a microVAX and a VME crate has been realized using two links: one is capable of DMA transfer and the other in Qbus I/O mapped. An effective rate higher than 0.5 Mbytes/s has been obtained transferring large data blocks with the DMA interface, while a rate of about 0.3 Mbytes/s has been reached with the I/O-mapped method.
