Embodiment Construction

[0019] The systems described below involve multi-core processing units (sometimes simply referred to as processing units) capable of high-speed or broadband communications. The disclosed processing unit includes a plurality of core central processing units (CPUs) including one core unit CPU managing the remaining core CPUs. The multi-core processing unit is miniaturized and its accompanying structure represents a reduction in weight and cost when compared to conventional systems, as will be explained below. In addition, the processing unit is capable of handling multiple parallel processes at high data rates. By way of example only, the processing unit is described as being in the optical communication system of the vehicle with a centralized structure. It should be appreciated that modern vehicles are required to be able to perform more and more parallel processing. According to at least one embodiment, the multi-core processing unit is capable of performing vehicular paral...

Abstract

A vehicle communication system that includes a plurality of functional system modules (FSMs) and a master system module (MSM) coupled to the FSMs. The MSM includes a multi-core processing unit that includes multiple functioning core assemblies (FCAs) and a managing core assembly (MCA). Each FCA includes a substrate carrying a core CPU and an optical interface circuit carried by a first edge of the substrate. The MCA includes a substrate having first and second major surfaces. The first major surface includes a plurality of rows of electrical connections, each of which are adapted to couple with one of the FCAs to enable communication between the core CPU (of MCA) and the core CPUs (of the FCAs). Each of the FCAs may have a second edge that abuts the first major surface at one of the plurality of rows of electrical connections.

Description

technical field [0001] The present disclosure relates to multi-core processing units, and in particular to multi-core processing units for optical communication systems in vehicles. Background technique [0002] Modern vehicles are required to handle an increasing number of electronic functions and electronic controls. When a vehicle gains new functionality, it often requires additional hardware, additional wiring, additional space, etc. This also generally increases the weight and cost of the vehicle. Accordingly, there is a need for a vehicle communication architecture that can support an increasing number of vehicle functions and controls, increasing demands for high-speed electronic operating devices, and the like. Contents of the invention [0003] According to one embodiment, a vehicle communication system is provided that includes a plurality of functional system modules and a main system module coupled to the plurality of functional system modules. The main syst...
