Alpha Data ADH-HTRAM module with T9000 and
Alpha AXP processors
- Size 4 Alpha HTRAM module
- 64 bit Alpha AXP RISC processor running at 233MHZ with 16MB
DRAM and 1MB Secondary Cache
- T9000 running at 25MHz
- 4 bi-directional DS links at 100Mb/sec
- PCI interface between Alpha and the T9000 (PCI rate up to
132MB/sec)
- Configurable from T9000 network
- Seamless integration to AD66
and T9 network
- Optional C104 routing board giving 8 DS links
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.
