Abstract
A method for performing data access via software according to communication protocol handling includes: calculating a time slot period and an upper limit of a processing time for performing a predetermined data processing according to time slot information defined in a communication protocol, a critical period and a time slot number; defining a clock frequency of a processor according to the upper limit of the processing time; and performing data access according to the slot time by the processor operating at the clock frequency. Accordingly, design inflexibility arising from performing data access via hardware is addressed, and a non-real-time issue caused by performing data access via software is also prevented.
Claims19
A method for performing data access according to communication protocol handling, the method comprising:
- calculating a time slot period and an upper limit of a processing time for performing predetermined data processing according to time slot information defined in a communication protocol, a critical period and a time slot number;
- defining a clock frequency according to the upper limit of the processing time;
- and

A method for performing data accessing according to a communication protocol, the method comprising:
- determining a first time length of a first time slot according to the communication protocol;
- defining a critical period and a time slot number of the first time slot;
- generating a second time slot according to the first time length, the critical period and the time slot number;
- defining a clock signal according to the second time slot;
- and
- performing the data access according to the clock signal.
