Application and packaging of the AT&T DSP3 parallel signal processor

Achieving the potential performance of highly parallel MIMD processor architectures is critically dependent on both the speed and routing capabilities of the network fabric. The routing network of the AT&T DSP3 processor is described together with an indication of how the 40 megabyte/s links can be configured to meet diverse application requirements. Scaling to very large configurations is aided by compact packaging. Silicon-on-silicon multi-chip modules together with a novel three-dimensional vertical interconnection technology are being used to repackage the DSP3 into the ultra-dense processor
