Abstract:
1. A method for controlling a memory access to a storage device, comprising the steps of: determining a number of waiting states for the memory access to the storage device by a central control unit, where the step of determining further comprises the step of analyzing at least one of a current state of the central control unit, a type of the storage device being accessed, and an address of the storage device being accessed; and comparing in an address comparator an address at a current point in time with an address at an earlier point in time to determine whether the current address is assigned to a storage device without required waiting states and to determine whether the current address prior to the current address and subsequent to the current address is assigned to a storage device with required waiting states, where the number of required waiting states for memory access with required waiting states is reduced if the memory accesses to the storage device with required waiting states involve one of incrementing addresses, same addresses, or addresses of the same memory page.
