The PowerPC 620 microprocessor: a high performance superscalar RISC microprocessor

The PowerPC 620 RISC microprocessor is the first chip for the application server and technical workstation product line within the PowerPC family. It utilizes a high performance microarchitecture with many advanced superscalar features to exploit instruction level parallelism. It is the first 64-bit implementation of the PowerPC architecture supporting both 32- and 64-bit application software, and is compatible with the PowerPC 601, PowerPC 603, and PowerPC 604 microprocessors.
