Abstract
Abstract The present invention relates to information processing equipment having communication capabilities capable of executing a communication protocol processing at high speed and comprising a main processor and a communication processor. If a load factor of the main processor is higher than a predetermined threshold value, the main processor executes the communication protocol processing and if the load factor of the main processor is lower than the predetermined threshold value, the communication processor executes the communication protocol processing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
An information processing equipment having communication capabilities comprising: a communication processor for controlling transmission and reception of a message; a main processor for controlling the information processing equipment; a load factor calculating means for calculating a load factor based on a load applied to the main processor; a memory means for storing the load factor which is calculated by the load factor calculating means; and a decision means for comparing the load factor stored in the memory means with a prescribed value to thereby determine a level of the load factor and selecting a processor for executing a communication protocol processing based on the level of the load factor.
Claim 2
Dependent Claim
109 words
An information processing equipment having communication capabilities comprising: a communication processor for controlling transmission and reception of a message; a main processor for controlling the information processing equipment; a load factor calculating means for calculating a load factor based on a load applied to the main processor; a memory means for storing the load factor which is calculated by the load factor calculating means; and a decision means for comparing the load factor stored in the memory means with a prescribed value to thereby determine a level of the load factor and selecting a processor for executing a communication protocol processing based on the level of the load factor.
Claim 3
Dependent Claim
37 words
An information processing equipment having communication capabilities according to claim 1, wherein the load factor calculating means calculates the load factor by counting the frequency of execution of a task to be executed by the main processor.
Claim 4
Dependent Claim
38 words
An information processing equipment having communication capabilities according to claim 2, wherein the load factor calculating means updates the frequency of execution of the task every time an interruption is made by a timer of an operating system.
Claim 5
Dependent Claim
96 words
An information processing equipment having communication capabilities according to claim 1, wherein there are low and high levels of the load factor, and the decision means decides to allow the main processor to execute the communication protocol processing if the level of the load factor is low which occurs when the load applied to the main processor is light or the decision means decides to allow the communication processor to execute the communication protocol processing if the level of the load factor is high which occurs when the load applied to the main processor is heavy.
Claim 6
Dependent Claim
26 words
An information processing equipment having communication capabilities according to claim 1, wherein the decision means is provided at the main processor and at the communication processor.
Claim 7
Dependent Claim
26 words
An information processing equipment having communication capabilities according to claim 4, wherein the decision means is provided at the main processor and at the communication processor.
Claim 8
Dependent Claim
27 words
An information processing equipment having communication capabilities according to claim 1, wherein the decision means determines the level of the load factor based on two threshold values.
Claim 9
Dependent Claim
27 words
An information processing equipment having communication capabilities according to claim 4, wherein the decision means determines the level of the load factor based on two threshold values.
