Abstract
For heterogeneous multi-core SoCs, the increasing demand of the memory capacity and bandwidth becomes a critical design challenge. In this paper, an on-demand memory sub-system is presented to efficiently control the memory access and memory resource allocation using adaptively allocated cache memory. The proposed adaptively allocated cache memory can dynamically assign a variable number of SRAM banks for process elements (PEs) to optimize the utilization of the centralized on-chip cache. In a wireless video entertainment system, a 7.13% execution time reduction and 10.53% energy reduction of memories can be achieved using the adaptively allocated cache memory.
