Abstract
Systems and methods for controlling access to a memory are provided. The system may include a buffer to store output data generated by a processing module, and provide the output data to a real-time module, and a buffer monitoring circuit to output an underflow approaching state indication in response to an amount of available data in the buffer being less than or equal to a threshold. The system may include a memory access module arranged to receive memory requests issued by the processing module, and configured to, while operating in a first mode, respond to memory requests with corresponding data retrieved from the memory, switch to operating in a second mode in response to receiving the underflow approaching state indication, and in response to operating in the second mode, respond to memory requests indicating the memory access module did not attempt to retrieve corresponding data from the memory.
