Architecture behavior

purpose scope

Purpose and scope

This unit owns the base system-register state record and the profile reset hook used to initialize the profile-owned part of architectural state.

concepts state

Base system-register state

BaseSystemRegisterState contains thread_ptr, global_ptr, core_state, core_id, thread_id, vendor, version, core_feature, core_feature_enable, tile_capacity, blocknum, blockid, and cycle, each represented as a Word.

The architecture-visible owner is _SystemRegisters, identified by PTO-STATE-ARCH-SYSTEM-REGISTERS.

rules interactions

Profile reset hook

ResetProfileState is implementation-defined and may be overridden by the active concrete profile. The default body in this owner sets _CurrentACR to 0 and clears _SystemRegisters.cycle to Zeros{PTO_XLEN}.

boundaries

Architectural boundaries

The default body does not write the other fields of BaseSystemRegisterState. This page therefore does not claim a reset value for fields that the owner leaves untouched.

Profile-specific reset behavior must remain behind the ResetProfileState hook rather than being inferred from a target implementation.

example usage

illustrative reset reading example

When checking the portable default, expect ACR0 and a zero cycle counter after ResetProfileState. Treat the value of vendor or tile_capacity as unresolved by this helper unless another current owner or active profile defines it.

NDF clauses

Bodies come from owning ASL. Dragging or buttons change only this page-session view order.

No NDF clause is attached to this unit.
