Title: Refresh control circuit for dynamic random access memory
Inventor: TAKAI YASUYUKI
IPC: G11C11/34
Filed: 1986-12-06
Abstract: PURPOSE:To improve the utilizing efficiency of a data bus by outputting a stored refresh request signal to a dynamic memory access control means in a predetermined timing satisfying the condition of a refresh cycle of a DRAM decided in advance. CONSTITUTION:A clock CK and a refresh request signal CO are outputted from a refresh request signal generating control circuit 1 to a refresh storage circuit 5. The storage circuit 5 stores the signal CO for a prescribed time and when a RFACK signal representing the enabled state of refresh is inputted from a dynamic memory access control (DMAC) circuit 2, an RFACK signal is retarded for a prescribed time and the result is outputted to the DMAC circuit 2 in a prescribed timing satisfying the refresh condition of the DRAM 4. Thus, even when a CPU 3 uses a bus for a long time, a refresh request signal is stored and outputted to satisfy the condition of the refresh cycle required by the DRAM 4.

Title: System and method for processing of data
Inventor: DEBITSUDO SHII BEIKAA
IPC: G09G5/36
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To satisfactorily solve conditions for performing the polling of a hardware from a software after respective commands by processing the commands and providing output to a display memory corresponding to the commands. SOLUTION: The command and data from a CPU 12 are sent to a graphic user interface(GUI) 18. When an output memory 33 inside the GUI 18 becomes a full state, an operation is performed so as to make the command from an input memory 32 be passed through a GUI FIFO memory 30 inside a video random access memory(VRAM) 24 and then be passed through the output memory 33. Thus, the GUI FIFO memory 30 functions as an auxiliary memory for receiving the command for causing the overflow of the memory 33. By mutually relating the memory 32 and the memory 33 inside the GUI 18 and the GUI FIFO memory 31 inside the VRAM 24, the need of the polling of the graphic user interface after the respective commands is eliminated.
