MADAR: An Address-Free Processor

arXiv:2606.15535v1 Announce Type: cross Abstract: In a modern processor, computing is the cheap part. Most of its area and energy go to \emph{addressing} -- moving operands to and from a register file and cache, and running the tags, ports, miss queues, and bypass networks that find a value where it was left. MADAR deletes that machinery by abolishing the address. All state circulates in rings of slots that advance one position per clock; instructions and data ride in the same slots; a value is named by its place in an orbit -- a \rp{} coordinate -- not by an address; a fixed station computes

Why this matters
Why now

The increasing demands of AI and advanced computing are pushing the limits of traditional processor architectures, driving innovation towards more efficient designs.

Why it’s important

This development proposes a fundamental shift in processor design that could dramatically reduce power consumption and increase computational efficiency, impacting the future of compute infrastructure.

What changes

Processor designs may move away from address-based memory management, leading to entirely new architectures that are more power-efficient and potentially faster for certain computational tasks.
