Two Powertrade-architecture 64b microprocessor chips are fabricated in 90nm dual strained-silicon SOI technology. The dual-processor chip has split clock domains and power planes, 1 MB L2 cache per core and a shared processor interconnect bus. The single-processor chip shares the dual's basic core and cache design
