general purpose registers

Concept

In the VAMP processor model described in the evidence, general purpose registers (gprs) are a 32-entry register file of 32-bit registers. They are addressed by index 0–31, with the first register always set to 0. In the assembler abstraction used for test generation, gprs are represented as a list of integers and are constrained by well-formedness rules to contain exactly 32 valid entries.

Overview

General purpose registers, abbreviated gprs in the cited VAMP processor model, are a register file used by processor operations. In the ISA-level configuration, the gprs component consists of 32 registers, each 32 bits wide. The registers are addressed by index from 0 to 31, and the first register is always set to 0. [C1]

Register File is_a The evidence explicitly states that general purpose registers are a register file consisting of 32 registers of 32 bits each.

special purpose registers contrasted_with The evidence describes both general purpose registers and special purpose registers as separate register files in the VAMP configuration, with different uses and addressing descriptions.
