Arrangement, device and method for controlling bus request signal generation

A system-on-chip (SOC) arrangement for controlling generation of a bus request signal, comprising:

• a bus;
• and
• a plurality of subsystems connected to the bus, each of the plurality of subsystems having a bus request signal generator,
• wherein at least one of the bus request signal generators in one of the subsystems generates a bus request signal so as to disperse a bus request point in a given process period, and each of the other bus request signal generators of the other subsystems generate a bus request signal according to the given bus request point.

A method of controlling generation of a bus request signal, comprising:

• generating a bus request signal according to a periodic value indicating an initial bus request period;
• generating a pulse signal as a function of a number of times that the bus request signal has been generated and a first threshold value;
• determining whether a given process period for generating the bus request signal has ended in response to the pulse signal to generate a determination result;
• and
• adjusting the periodic value to control the process period of the bus request signal, based on the determination result.

A device, comprising:

• a bus request signal generating circuit for generating a bus request signal under control of a counter;
• a pulse signal generating circuit for generating a pulse signal as a function of a number of times the bus request signal generating circuit has generated a bus request signal and a first threshold value;
• a determining circuit for generating a determination result representing whether a given process period for generating the bus request signal has ended, as a function of the pulse signal;
• and
• a control circuit for controlling the counter to adjust the process period for generating the bus request signal, based on the determination result.
