  • Memory controller having a multiplexer selecting either second set of input signals or converted signals from first set of input signals by a bus mode input
    Patent number: 6742058
    Abstract: A configurable memory controller for an AMBA system is described. This configurable memory controller selects one of two possible modes of operation. The technique of configuring the memory controller provides fundamental memory control in the AMBA system while also allowing for a switching mechanism to select between the two modes, each of which entails its own set of special signal definitions. The configurable memory controller may be connected either on the AHB bus or directly connected to the ARM central processing unit core with a mechanism to switch between the two modes of operation.
