Arrangement, device and method for controlling bus request signal generation

摘要

A device, arrangement and method may control bus request timing to disperse bus access timing, so that adverse effects of concentration-on-bus phenomenon may be avoided. The device may include a bus request signal generating circuit may generate a bus request signal under control of a counter, and a pulse signal generating circuit may generate 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. The device may include a determining circuit and a control circuit. The determining circuit may generate a determination result representing whether a given process period for generating the bus request signal has ended as a function of the pulse signal. The control circuit may control the counter to adjust the process period for generating the bus request signal, based on the determination result.
