- Abstract
- A smart TV system-on-chip (SoC) has very heavy computation and memory demands that must be met with low-cost components. As a result, there is potentially an extremely high utilization of the channel between the SoC and its memory chip. This paper presents the design of a new memory access scheduler customized for the type of memory traffic typically encountered with smart TVs. This includes special accumulated hard real-time graphics requirements, user response-sensitive soft real-time requirements, and the need to provide high memory throughput and priority-handling capabilities even under extremely heavy memory traffic conditions. The simulation results show that the proposed memory access scheduler is able to achieve up to 98% of the ideal upper bound memory throughput when faced with extremely heavy memory traffic-this is a significant improvement over previous schedulers. Novel future prediction and light-handed priority handling methods are used to achieve these results while satisfying the unique real-time requirements of smart TVs.
