Abstract
The invention discloses an image multilayer data processing method and device. The image comprises multiple pieces of map layer data. The device comprises a data acquisition unit, a filling unit, buffer units, a priority scheduling unit, and a map layer superposing unit. The method adjusts the priority of a certain buffer unit only when a preset row of the buffer unit is filled with the map layer data so that the batch access can be carried out on the memory address of the same map layer data as much as possible when the map layer data is acquired. Therefore, consumption due to DDR reading different addresses is saved and the utilization rate of the DDR is increased. Further, the method, by dynamically adjusting the priority of each buffer unit, enables the map layer data to be quickly filled and parallel map layer data processing, thereby enhancing system performance and facilitating map layer superposition.

Figure layer data time, stacking chart's layer data formed image.
When using image multi-layer data processing means, first data capture unit obtains multiple figures of image
Layer data.In the present embodiment, figure layer data is saved in DDR.Data capture unit can pass through
Bus obtains figure layer data from DDR.Then fill unit to fill the first figure layer data to the first caching
In unit, described first buffer unit is the buffer unit that the first figure layer data is corresponding.First buffer unit
For a certain buffer unit in some buffer units, for convenience of description, the first buffer unit is in Fig. 1
Buffer unit a, data capture unit after reading the first figure layer data from DDR, fill unit meeting
First figure layer data is packed in buffer unit a.In the present embodiment, data capture unit and filling out
Filling unit is the electronic component with digital independent function and data processing function, such as DMA.
The then line number of the buffer area that priority adjustment unit has been filled by the first data at the first buffer unit
Reach first when presetting line number, to adjust the priority of the first buffer unit.As in figure 2 it is shown, buffer unit
Including 5 row cache districts, buffer area may be used for storage figure layer data.With the buffer unit in Fig. 2 it is
As a example by first buffer unit, the default line number (i.e. first presets line number) of its correspondence is 2 row, then fill
When the buffer area line number that unit has been filled by the first figure layer data in the first buffer unit reaches 2 row, meeting
Adjust the priority of the first buffer unit.In the present embodiment, described filling unit performs padding
Buffer unit be the buffer unit that priority is the highest, then " priority adjustment unit is at the first buffer unit

Second when presetting line number, and the priority of the second buffer unit is adjusted to minimum.Second buffer unit excellent
After first level is adjusted, it is possible to start next layer data of the second figure layer data is filled with.
By dynamically adjusting the priority of each buffer unit, so that each figure layer data can be quick
Be packed into correspondence buffer unit in so that multiple figure layer data process be parallel.When all of slow
When being filled with the figure layer data of correspondence in memory cell, each figure layer data can be entered by map overlay unit
Row superposition, to ultimately form image.
In the present embodiment, described device also includes FIFO memory element 104, and described FIFO stores
Unit is connected with buffer unit, and the corresponding FIFO memory element of each buffer unit, described FIFO stores
Unit is connected with map overlay unit；The described FIFO memory element figure number of plies in memory buffers unit
According to；Described map overlay unit figure layer data of storage in superposition all FIFO memory element forms figure
Picture.FIFO memory element is the dual port buffer of a FIFO, and i.e. first enters its interior data
First is moved out of, the input port of one of them memorizer, and another mouthful is the delivery outlet of memorizer, can
For processing mass data stream, to improve the performance of system.Figure layer data is being packed into buffer unit
After, then enter the FIFO memory element that this buffer unit is corresponding from buffer unit, carry out of short duration storage.
So, when map overlay unit only need to all store figure layer data in all of FIFO memory element, right
In all FIFO memory element, the figure layer data of storage forms image, substantially increases the process of figure layer data
Efficiency.
For some the figure layer data obtained from DDR, before the buffer unit being packed into correspondence, need
Carry out certain map function, in order to the figure layer data after conversion process is carried out by map overlay unit
Superposition.Thus in the present embodiment, described device also includes converter unit, described converter unit is with slow
Memory cell connects, and described converter unit is for carrying out conversion process to the figure layer data in buffer unit.Institute
State conversion process and include scaling process, rotation processing etc..
In the present embodiment, described device also includes line number dispensing unit 107, described line number dispensing unit
For configuring the default line number that each buffer unit is corresponding.The default line number of each buffer unit can basis
The number of the buffer area line number that buffer unit is comprised and arrange, such as can be set to delay by default line number
The half of the total line number of buffer area that memory cell is comprised, it is of course also possible to default line number is set to 1/2 row,
1/3 row etc..
