The known solutions to this problem typically involve a number of global counters and queues. Here a very simple algorithm is presented which needs only two semaphores for synchronisation and no other global objects...

Design and Implementation of a Photo Card Reader by a High-integration Chip Solution

In this paper, we propose a design and implementation of photography card reader by utilizing a high integration chip solution. The system uses the two machines: one is a popular card reader and the other is a photo player. To reach a higher level of performance and system flexibility, we integrate many independent components into a single chip and provide a system on chip (SOC) solution. As a ...
