Biological signal measuring apparatus
First Claim
1. A biological signal measuring apparatus including:
- a biological signal measuring sensor configured to measure a biological signal;
a first processor configured to perform a first processing on the measured biological signal,a second processor configured to perform a second processing on the measured biological signal,wherein the first processor and the second processor are independently controllable to execute the first processing and the second processing, andthe first processor is further configured to determine at least one of the measured biological signal satisfies a given condition and a load of the first processor performing the first processing exceeds a given level, and control the second processor to perform the second processing based on a result of the determination.

Abstract
The calculation amount of the whole can be reduced. A biological signal measuring apparatus includes a biological signal measuring unit which measures a biological signal; and a calculation processing unit which performs calculation processes on the measured biological signal, wherein the calculation processing unit has: a first calculation processing unit which performs calculation processes required for calculating the biological signal, and which is independently controllable; and a second calculation processing unit which performs a specific calculation process, and which is independently controllable, and, when the first calculation processing unit satisfies given conditions, the second calculation processing unit is caused to perform the specific calculation process.
