Abstract
In a data processing system, a memory control unit (22) provides a control register bit field (60), logic, and a state machine (62) which facilitate a programmable number of clocks for an initial access to an on-chip memory (20). Specifically, the memory control unit (22) allows an external user to modify memory control signals to provide consistent access times across different frequencies of the system clock and allows memory control signals to be modified to optimize access time dynamically. Also, programmable control of the control signals to the memory (20) allows the memory to operate at system clock frequencies which are higher than expected.
