Problems solved by technology

[0004] When it is necessary to realize the high-speed computing performance and versatility in the small power-saving mode at the same time, the previous general-purpose processors or application specific integrated circuits (Application Specific Integrated Circuit, ASIC) cannot achieve the high-speed computing performance and versatility in the small power-saving mode. one of the problems
General-purpose processors can improve computing performance by grouping multiple processors, but do not meet conditions such as small power-saving modes
ASIC has high computing performance, but lacks versatility

Embodiment 1

[0089] First, the information processing device of the first embodiment will be described. figure 2 It is a block diagram of the configuration of the information processing device of the first embodiment.

[0090] The information processing device 200 includes a multi-core processor 101 as a dynamic reconfiguration processing unit, a packet input and output unit (packet I / O) 100, a storage unit that is a memory 103, a network I / F-i (i=1 to N) 203 (203- 1 to 203-N), the communication line connection unit 204 (204-1 to 204-N), and the switch 102. This information processing device 200 exemplifies the Figure 4 Since the structure used in the backend system of , the HDD 174, the HDD data update unit 212, and the VOD server 304 are further shown in the figure. explained later image 3 In the information processing device used in the border network, there may be a configuration that does not include the VOD server 304 or even the HDD 174 and the HDD data update unit 212 .

Embodiment 2

[0209] In Embodiment 1, the mode in which the communication state is changed from the wideband transmission state to the narrowband transmission state according to the transmission data is described, but in the case where the Proto 1106 of the packet is TCP or RTCP (RTP Control Protocol, RTP Control Protocol), it is also The communication state can be changed from the wideband transmission state to the narrowband transmission state according to the received packet.

[0210] In the second embodiment, the communication state update unit 119 accumulates the byte accumulation amount F-BYT 1212 and changes the F-STATE 1211 from the wideband transmission state to the narrowband transmission state.

[0211] When the Proto 1106 of the received packet is TCP, the communication status update unit 119 adds the difference between the PACK 1113 described in the received packet and the F-SEQ 1205 of the communication status to the accumulated byte amount F-BYT 1212 . Furthermore, when the s...

Abstract

It is an object of the present invention to provide an information processing apparatus equipped with a many-core processor providing a VOD service having a fast playing response speed with a small size and power saving and an information processing system. In the information processing apparatus equipped with a many-core processor configuring an operation matrix that performs a reconfiguration for each packet based on a communication state, the functions and wirings of the operation matrix are reconfigured so that data is transmitted in a wideband transmission process when a transmitted data amount is smaller than a preset threshold value and the data is transmitted in a narrowband transmission process when the transmitted data amount is larger than the threshold value by comparing the transmitted data amount obtained by counting a transmission data amount of a transmission byte counter with the threshold value in a transmission amount / time determining unit and changing a communication state in a wideband / narrowband transmission state changing unit according to the comparison result.

Description

technical field [0001] The present invention relates to changing data stored inside the device, generating and sending a new packet to the outside, by connecting to a network and receiving a packet transmitted via the network, performing different processes according to the communication status between terminals or hosts that are sending and receiving packets, and changing data stored inside the device. Technology that provides server services such as video distribution. Background technique [0002] With the parallel development of broadcast communication convergence and ubiquitous computing (ubiquitous computing), users from both the back end and the access side request the diversification of services provided by the server and the improvement of the perceived speed of the services. Therefore, it is necessary to realize various server services (VOD (Video on Demand, video on demand)) by distributing the applications deployed on the border network, and improve the computing...
