Abstract: A microfluidic detection unit comprises at least one fluid injection section, a fluid storage section and a detection section. Each fluid injection section defines a fluid outlet; the fluid storage section is in gas communication with the atmosphere and defines a fluid inlet; the detection section defines a first end in communication with the fluid outlet and a second end in communication with the fluid inlet. A height difference is defined between the fluid outlet and the fluid inlet along the direction of gravity. When a first fluid is injected from the at least one fluid injection section, the first fluid is driven by gravity to pass through the detection section and accumulate to form a droplet at the fluid inlet, such that a state of fluid pressure equilibrium of the first fluid is established.

Abstract: A memory mapping method for mapping a data array into a memory. The memory mapping method provides the two-directional access in the data array. The memory mapping method first equally divides each row of the data array into some basic units based on the number of the columns of the data array. Next, a predetermined number of adjacent basic units in the same column are arranged into a basic memory block. Finally, the basic memory blocks are mapped into the memory.
