Methods of its use in a hybrid system together with an RTL processor model and a mechanism for generating universal input actions for dissimilar components are described. 06/18/2013 15:55 Methodology for designing a protocol for the coherence of the cache memory of the 1st and 2nd levels of the MCST-R1000 microprocessor The description of the coherence support protocol for the MCST-R1000 system-on-chip is presented. The problems that have arisen during the creation of the protocol and the ways of their solution are considered. 06/18/2013 15:44 Ensuring the ordering of DMA operations in NUMA systems using the pre-caching method The problem of orderly execution of DMA-operations is considered. The mechanism of pre-caching is described as one of the ways to solve the problem. The details of the implementation of this mechanism in SoC "Elbrus-4S +" are given. The described method is compared with other known methods for solving the problem. 06/18/2013 15:33 Level 3 cache and coherence support for the Elbrus-4S + microprocessor General characteristics and principles of operation of the third level cache of the Elbrus-4C + microprocessor are given. The description of the structural scheme features is given: separate pipelines of tags and data, buffer of processed requests, buffer of preempted modified lines. The protocols of the local directory and request processing are described. The time of access to the cache memory of the developed microprocessor and foreign analogues is compared. 04/26/2013 15:51 Organization of coherence support in the MCST-R1000 system-on-chip On the basis of SoC, computing systems can be built, including up to four MCST-R1000 microcircuits, jointly containing up to 36 cache memory devices. One of the most important tasks in building such a system is ensuring data consistency. This article is devoted to the description of its solution. 03.07.2012 16:08 Organization of coherence support in the MCST-R1000 system-on-chip On the basis of SoC, computing systems can be built, including up to four MCST-R1000 microcircuits, jointly containing up to 36 cache memory devices. One of the most important tasks in building such a system is ensuring data consistency. 06/05/2011 15:56 The problem of maintaining the coherence of caches in systems on a chip Elbrus-S, Elbrus-2S The conflict Invalidate-Invalidate is described, the possibility of which entails the need for unnecessary data transfers between the owners of the Owned and Shared states or the implementation of mechanisms that detect the conflict; such a mechanism, implemented in the Elbrus-S system, is considered, and an improved one, designed for operation in the Elbrus-2S system, is proposed. news 04/10/2014 13:46 Выпуск журнала «Вопросы радиоэлектроники», серия ЭВТ 31.01.2013 00:00 Cеминар «Задачи дальнейших работ по оптимизирующему компилятору ВК семейства “Эльбрус”» 28.06.2012 00:00 Научный семинар цикла «Перспективы применения мозго-машинных интерфейсов для высоконадежного управления сложными системами» Это интересно Российские универсальные микропроцессоры и ВК высокой производительности: результаты и взгляд в будущее Подробнее ...
