A computing system and a transposition method therefor. One aspect of the present disclosure provides a computing system that variably determines an input/output unit of a memory depending on a processing unit or an output unit of a processor, and a transposition method for supporting same.

Computing system and transposition method therefor

A Winograd algorithm multiplies a first matrix by a second matrix to generate a third matrix. A plurality of second accumulated value calculation units, accumulates second multiplication values obtained by multiplying each of paired element values of the second matrix, a second accumulated value output unit outputting selecting and outputting one of output values of adjacent second accumulated value calculation unit and an accumulated second multiplication value as a second accumulated value, a third accumulated value output unit including a plurality of third accumulated value calculation units and generating third accumulated value, and one or more row element value calculation units, of which one row element value calculation unit accumulates first matrix element multiplication values obtained by multiplying each of the paired element values of the first matrix, and calculates element values of the third matrix using the accumulated first matrix element multiplication value and the second accumulated value.

Matrix multiplication method and device based on Winograd algorithm

A computation circuit includes a plurality of processing elements and a common accumulator. The plurality of processing elements are sequentially coupled in series, and performs a multiply and accumulate (MAC) operation on a weight signal and at least one of two or more input signals received in each unit cycle. The common accumulator is sequentially and cyclically coupled to first to Kth processing elements among the plurality of processing elements, and configured to receive a computation value outputted from a processing element coupled thereto among the first to Kth processing elements, and store computation information. The K is decided based on values of the two or more input signals and the number of guard bits included in one processing element.

Computation circuit including a plurality of processing elements coupled to a common accumulator, a computation device and a system including the same

A computation device includes a buffer memory which provides first to b input feature sets to the computation unit. The buffer memory includes first to nmemories, and configured to divide and store the first to ninput feature sets each including a plurality of features in the first to nmemories, respectively. The plurality of features of one input feature set is divided and stored into the first to nmemories. Features having the same turn in the first to ninput feature sets are stored one by one in the first to nmemories.

Buffer memory, and computation device and system using the same

A method of processing ray data the method including receiving ray data stored in input buffers; updating a property of the ray data based on a result of intersection traversal of the ray data; and outputting the ray data to an output buffer or to a feedback buffer from among the input buffers based on the updated property of the ray data. When there is insufficient space in the output buffer to store the ray data, outputting the ray data to the feedback buffer.

Ray tracing unit and method for processing ray data

Disclosed is a process for the preparation of a high stereospecific (isotactic) polybutylene polymer comprising the step of polymerizing a reactive monomer, 1-butene, which is used or is not used as a solvent, in the presence of catalyst and inert gas. According to the present invention, it is possible to prepare a high stereospecific polybutylene polymer in much higher activity than that of any other known processes for the preparation of a high stereospecific polybutylene polymer. The high stereospecific polybutylene polymer according to the present invention is a homopolymer of 1-butene, or a copolymer containing a-olefin and up to 40% by weight of a comonomer, wherein titanium in the catalyst residues is not detected in the ppm level, stereospecificity (Isotactic Index, mmmm %) determined byC-NMR is 96 or more, molecular weight distribution (Mw/Mn) is 3-6, and molecular weight distribution (Mw/Mn) can be controlled to 8 or more.
