A 16-issue multiple-program-counter microprocessor with point-to-point scalar operand network

This microprocessor explores an architectural solution to scalability problems in scalar operand networks. The 0.15/spl mu/m 6M process, 331 mm/sup 2/ research prototype issues 16 unique instructions per cycle and uses an on-chip point-to-point scalar operand network to transfer operands among distributed functional units.
