A New Data Transfer Scheme for eMMC Connected Subsystems
Deng Shulan · Advances in intelligent systems research/Advances in Intelligent Systems Research · 2014
One of the issues in data transfer between host CPU and its eMMC connected subsystem is to determine when to send data from host to subsystem and when to receive data from subsystem to host with least CPU interference.The conventional approach to achieving data transfer synchronization is by polling, which impacts CPU bandwidth and potentially affects the subsystem's performance.This paper proposes an automatic two-way data transfer synchronization scheme that requires no involvement of host CPU in data transfer synchronization and offers real-time synchronization performance on subsystem side.
