Processor Components<br />

All entries in the TLB are shown, regardless of security state or ASID. Entries outside the<br />

current state, or that do not match the current ASID, are not be used by the CPU for physical<br />

address translations.<br />

This view is available only for TLBs with a limited, finite size. It is not supported when the<br />

tlb_prefetch option is enabled, because there is no linear indexing of TLB entries in the infinite<br />

pre-fetching TLB model.<br />

Entries by MVA<br />

The Address field corresponds to the Modified Virtual Address (MVA) from which a TLB entry<br />

is translated.<br />

This view is specific to a particular security state and ASID. You can control this by opening a<br />

Register view in the debugger window. You can change the registers NS and ASID to view the<br />

corresponding TLB entries.<br />

4.12.7 Verification and Testing<br />

The <strong>ARM</strong>AEMv7AMPCT has been tested using the <strong>ARM</strong> Architecture Verification Suite<br />

(AVS).<br />

4.12.8 Performance<br />

The <strong>ARM</strong>AEMv7AMPCT model provides high performance in all areas except VFP and<br />

NEON instruction set execution which currently does not use code translation technology.<br />

4.12.9 Library dependencies<br />

The <strong>ARM</strong>AEMv7AMPCT model has no dependencies on external libraries.<br />

4.12.10 Boundary features and architectural checkers<br />

Boundary features and architectural checkers are model capabilities that help your development<br />

and testing process by exposing latent problems in the target code. For more information on<br />

these capabilities, see Appendix A AEM <strong>ARM</strong>v7-A specifics.<br />
