Embodiment Construction

[0030] The present invention will be described with respect to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims. The scale and relative scale do not correspond to actual reductions to practice of the invention.

[0031] Furthermore, the terms first, second, etc. in the description and in the claims are used to distinguish between similar elements and not necessarily to describe an order temporally, spatially, in ranking or in any other way. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0032] It is to be noted that the term "comprising", used in the claims, should not be interpreted as being limited to the means listed thereafter; it does not exclude other elements or steps. Accordingly, the term should be in...

Abstract

The invention relates to a high speed communication system. A method for communicating between a master and a plurality of slaves includes the step of generating a communication frame including generating a slave data frame in each slave. The slave data frame has a data packet including one or more data bytes and at least one gap of variable time length comprising no information in the slave data frame. The gap may be at the beginning of said slave data frame before the beginning of the first data byte of said data packet and / or at the end of said data packet after the end of a last data byte of said data packet, where the gaps have a time length dependency based on parameters locally stored in each of said at least one slave. The slave data frame is transmitted sequentially where the gap increases for each subsequent slave.

Description

technical field [0001] The present invention relates to the field of data communication. More specifically, it concerns master-slave communication. Background technique [0002] Existing network systems usually provide connections between different electronic components and their controllers through Local Interconnect Network (LIN) or Controller Area Network (CAN) systems, or other systems, and establish communication protocols between them. [0003] For example, in automotive applications several bus systems are already in place. For example, a LIN network connects several slave devices to a master unit. However, the bandwidth limit is about 20 kilobaud (kbaud), which is unsatisfactory for many applications. Nonetheless, the LIN bus is seen as a cost-effective solution. Other bus systems (such as CAN bus, Ethernet bus, or Flexray-based networks) are fast communication interfaces. However, network implementation is relatively costly. Examples of CAN are complex, diffic...
