PowerPCpiirit
PowerPCpiirit is a fictional processor concept described in speculative discussions as a hybrid extension of the IBM PowerPC ISA. It is not an implemented product and has no official standard. The term is used to explore ideas about architectural configurability, parallelism, and backward compatibility with existing PowerPC software.
Overview: The concept envisions a 64-bit PowerPC base with an optional Piirit extension intended to improve
Architecture and features: The base core is described as a high-performance, superscalar design with a large
Development status: The PowerPCpiirit proposal exists primarily as a thought experiment within academic and hobbyist circles.
