Problems solved by technology

Each cell in a two-dimensional array with a uniform structure can only communicate directly with adjacent cells, which is limited by the communication method. When removing a single cell, not only the wiring is complicated, but the number of cells that can be removed is also limited. column) large waste of resources when removing - a large number of normal cells are removed due to faulty cells

Embodiment Construction

[0037] see figure 2 , the embryonic bionic self-repair structure based on the bus structure provided by the present invention adopts a bus array, and the bus array is composed of working cells, backup cells, input cells, output cells and a bus, X represents the input end of the array, and U represents the array All the cells are connected to the bus in parallel, wherein the input cells are connected to the bus at the input terminal X of the bus array, and the output cells are connected to the bus at the output terminal U of the bus array.

[0038] The bus simulates the function of body fluid in cell endocrine communication, and is a public channel for information transmission. The number of wires in the bus can be flexibly set according to the actual situation. The number of bits of the bus designed by the present invention is at least 11, and is composed of a fault signal line, a command 1 signal, a command 2 signal line, an address signal line and a data signal line. imag...

Abstract

The invention discloses a structure and a method of bus-structure-based embryonic biomimetic self-healing. The self-healing structure is provided with a bus array. The bus array comprises working cells, backup cells, an input cell, an output cell and a bus. All the cells are connected to the bus in parallel. The input cell is connected to the bus at the input end of the bus array. The output cell is connected to the bus at the output end of the bus array. All the cells of the self-healing structure are connected to the bus, so that wiring is simple. A configuration memory stores no configuration information redundancy but configuration information of the cells, so that consumption of storage resources is low. A self-healing mechanism requires direct intervention of failing cells and the backup cells only, configuration information and routing of other cells are unchanged, and the efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of electronic technology and bionic self-repair, and in particular relates to an embryo-type bionic self-repair structure and method based on a bus structure. Background technique [0002] With the complexity of digital systems, fault tolerance has become an important indicator to measure the performance of a system [1]. The traditional approach is to improve the reliability of the system by performing multi-mode hardware redundancy on key components [2]. That is, through the analysis of the failure mode in advance, the key components are redundantly configured and switched when a failure occurs to ensure the normal operation of the system. However, due to the limitation of the size of the hardware redundancy, it is impossible to carry out backup redundancy for all components, and only key components can be redundant, so the fault tolerance is limited [3, 4]. In addition, hardware redundancy is based on pe...
