US 9,791,509 B2 · Monitoring microprocessor interface information for a preset service using an address based filter

Abstract

Embodiments of the present invention, which relate to the field of electronic technologies, provide a monitoring method, a monitoring apparatus, and an electronic device, which can accurately locate an error point in MPI information delivered by a system chip. The apparatus may include: an address filter, a read/write controller connected to the address filter, and a memory connected to the read/write controller, where the address filter is configured to acquire multiple pieces of MPI information, and obtain, by filtering the multiple pieces of MPI information, first MPI information corresponding to a first service that is preset; the read/write controller is configured to write, into the memory according to a time sequence of receiving the first MPI information, the first MPI information that is obtained by the address filter by filtering; and the memory is configured to store the first MPI information written by the read/write controller.

Dependent claims

A monitoring apparatus incorporated within a service chip that receives a second microprocessor interface (MPI) information from a system chip, the monitoring apparatus comprising:

an address filter for the second MPI information;
a read/write controller connected to the address filter;
and
a memory connected to the read/write controller;
wherein the address filter is configured to acquire:
multiple pieces of the second MPI information, and
a first comparison value and a first expected value that separately correspond to a first service that is preset on the service chip;
wherein the address filter is further configured to obtain a first MPI information which corresponds to the first service that is preset by filtering the multiple pieces of the second MPI information according to:
the second MPI information, the first comparison value, and the first expected value;
wherein the read/write controller is configured to receive the first MPI information,
wherein the read/write controller is further configured to write the first MPI information into the memory according to a time sequence of receiving the first MPI information, and
wherein the memory is configured to store the first MPI information written by the read/write controller.
