Abstract: A module for controlling a mass memory of a satellite is provided to increase processing efficiency of data stored in the mass memory and correctly download the stored data to the ground in a needed period by advancing a command of a CPU with priority set in hardware. An access arbiter(110) determines an input signal cycle applied to the mass memory(30) among the input signal cycles for multiple tasks to be processed on the basis of the control from the CPU of the satellite by the set priority. A multiplexer(120) generates a control and access signal to be applied to the mass memory according to determination of the access arbiter. An error corrector(130) calculates an ECC(Error Checking and Correction) code value for correcting an error generated in the mass memory. An initializer(140) sets up operation configuration by setting a register value of the mass memory. A task unit(150) sets up, generates, and stores a cycle signal for executing each task by the control of the access arbiter.
