Document Type and Number:
Japanese Patent JP4520538
Kind Code:
B2
Abstract:
The invention relates to a method and system by means of which a large number of peripheral modules (TRn) can request service from a controller, e.g. in form of an interrupt request. Congestion of service requests is prevented in advance by assigning a predetermined time slot to each peripheral module (TRn) during which it is allowed to ask for service from the controller. The time slots are coordinated by a time slot counter which is stepped with a clock signal (CLK). The time slot counters of the different peripheral modules are synchronized with a synchronization signal (SYNC). The peripheral modules (TRn) may include subperipheral modules, whereby each subperipheral module can request service independently, or a gate N1 coupled to a register SR1 may be employed for detecting that a subperipheral module requires service.
