N2 - The dynamic memory controller plays an important role in system-on-a-chip (SoC) designs to provide enough memory bandwidth through external memory for DSP and multimedia processing. However, the overhead cycles in accessing the data located in external memory have much influence on the SoC performance. In this paper, we propose a low latency memory controller with AHB interface to reduce the overhead cycles for the SDR memory access in the SoC designs. Through the pre-calculated addresses of impending transfers, two memory control schemes, i.e. Burst terminates Burst (BTB) and Anticipative Row Activation (ARA), are used to reduce the latency of SDR memory access. The experimental results show that the proposed memory controller reduces the memory bandwidth by 33% in a typical MPEG-4 video decoding system.
