Alpha Data ADH-HTRAM module with T9000 and Alpha AXP processors

Features
Description

The ADH-HTRAM is a size 4 HTRAM module including both an Alpha AXP and a T9000 processor. The two processors are interfaced over the on-board PCI bus for maximum inter-processor communication bandwidth. This compact unit offers superb processing performance along with access to T9000 link technology, making it a powerful building block for a parallel processing system. This module enhances existing T9000 systems with the huge floating point power of Alpha processors. Parallel compilers for the ADH-HTRAM are available from 3L.
