Abstract
An integrated circuit may have a memory controller that interfaces between master processing modules and system memory. A scheduling module may be used to handle memory access requests received from multiple master modules. The scheduling module may arrange the received memory access requests in an order for fulfillment with system memory. A bypass module may be used to provide a low latency bypass path that allows memory access requests to bypass the scheduling module. The bypass module may include an eligibility detection module that identifies memory access requests eligible for scheduler bypassing, a port selection module that provides a low latency bypass path for the eligible memory access requests, multiplexing circuitry that selects between memory access requests provided from the low latency bypass path and from the output of the scheduling module, and a masking module that prevents redundant fulfillment of memory access requests.
