Abstract

The invention relates to computer technology and is intended for use in the digital optimal synthesis and reproduction of an image, sound accompaniment and other signals, to facilitate recording of such signals on a carrier or their display on a screen. The proposed method increases operating speed and minimises the cost of equipment used in applying it. It involves the continual regeneration of a set of pixels which form a given frame sequence, using identical processors the number n of which is derived from the formula shown, where k is the number of frames per second, p is the number of pixels per frame, t0 is the processing time taken by one processor to regenerate one pixel, C0 is the cost of the collectively used circuit components, and C1 is the cost of one processor and the equipment dedicated to it. An example is given of the application of this method using a device based on the principle of parallel processing of input data when processing pixels and comprising an external memory, control device, input switch, channel selectors with switches, two buffer memories, identical processors, and a screen memory.

DISCLOSURE OF INVENTION

The purpose of the invention is to increase the speed of operation of the invention, to minimize the cost of hardware-related costs and to increase its utilization.

1 ₀ - time of restoration (processing) of a single pixel in the middle of the process,

C ₀ - the cost of the collectively used components of the scheme,

With _χ - the cost of one process and is used only for them.

The values of the upper and lower borders, which select the optimal number of processes, are based on the following shipments.

In general, the optimization tool is the number of processes η. The lower boundary of the quantity η is divided by the following method.

The processing time of the single processor is the same as the total number of processors, but it must not be less than the calculation time of the process unit. When it comes to fair equality:

B 1 α + - = - = 1 (1) η to where I is the generation time of a single frame;

α and b are factors that are shared by:

where α = Ιο.

Ρ and η = 1,

where follows b + { ₀ = ρΙο or b = (ρ-1) ϊ _0> where 1 ₀ is the time of processing one pixel.

Bearing in mind that ρ »1 and π having taken α = 1 ₀ (1), you can write in the form

/ ₀ +, wherever follows

Since, on the other hand, the component (2) contains a product that eliminates the quality of the image, reducing the value of the condition that is given to (2) and not paying attention to In general, only the number of processes η is acceptable for which it is fair:

The outer boundary of the quantity η is divided by the following method. \ ¥ 096/08789 ΡСΤ / ΙШ95 / 00203

³ pixels.

As noted above, while framing one of the caddras, the expression / ₀ = is shared. If you must have a unit cost of

the time linearly depends on the number of used processes η and is dependent on the type С ₀ + С] П], the speed of the unit is connected to the environment

where ς is the coefficient of sociality.

Equating to zero the derivative άθ / άη, we obtain the simplest condition, which, however, meets the condition:

Like πρ and any χ η value

η, defined (4), corresponds to the minimum value (λ

How does an increase in the number of processes then lead to the growth of β, which is fair inequality:

The combination of (3) and (5) leads to the establishment of the values of the lower and upper boundaries of the selection of the optimal number "η".

Β in the event that, as a result of the implementation of the inequality, the number η does not turn out to be integer, but otherwise, then it will be carbonized to the nearest larger integer.

Otherwise, the integer η can be obtained by making the number of processes step-by-step in accordance with the following condition:
