An in-system routing strategy for evolvable hardware programmable platforms

Abstract

One of the major limiting fuctors for the development of hardware plulfornis able lo siipport evolvuble hurhvure principles is [he luck of simple and compact insystem dynumic roiiting strutegies. In [his paper we shull present U progrunimuble hurdwure urchitecture whose internul orgunixtion permils io perform dynumic roirting processes, The urchilecture is bused on U regirlur bidinirnsionul urruy of fiinctionul cells. A hierurchicul luyered orgunizution hus been provided ,for ihese cells. Specijk roiiting re.soiirces huve been inclirded in one of these Iuyers. .so thui they permit to constriici in un incrementul wuy routing puths among the fiincf ionul cells. The dynumic roiiting slrutegy is bused on U replicalion process thui is able to conneci U source cell with vurioirs turgei cells. One of the major udvuniuges ofthe proposed routing struiegy lies in ihe fuct thul its complexily grows only linearly with the array s i x . Firrthermore it is .scufuble, uccommoduting ivithoirt performance degradation to m y array size. Behuviorul hurdivure descriptions huve been created for the fiinctionul cells thul constitiiie /he array. A s the simzrlulion and syn1hesi.s resirlt.~ will show. the proposed roiiling strutegv will permit the implementution of uctirul evolvuble hardware principles.

The POEtic Electronic Tissue and Its Role in the Emulation of Large-Scale Biologically Inspired Spiking Neural Networks Models

“…The last phase, largely inspired by Moreno Arostegui [3] , creates a shortest path between the selected source and the selected targets. An example involving 8 sources and 8 targets is shown in fi gure 10 , for a densely connected network.…”

A Dynamic Routing Algorithm for a Bio-inspired Reconfigurable Circuit

“…Therefore, a second layer was added on top of the molecules, implementing a distributed dynamic routing algorithm. This algorithm uses an optimized version of the dynamic routing presented by Moreno in [5], to which we supplied a distributed control to where there is no global control of the routing process.…”

“…The last phase, largely inspired by [5], creates a shortest path between the selected source and the selected targets. An example involving 8 sources and 8 targets is shown in figure 6, for a densely connected network.…”

“…Section 4 fully explains the dynamic routing algorithm implemented in order to ease the creation of long distance paths into the chip. l u t [ 0 ] l u t [ 1 ] l u t [ 2 ] l u t [ 3 ] l u t [ 4 ] l u t [ 5 ] l u t [ 6 ] l u t [ 7 ] l u t [ 8 ] l u t [ 9 ] [ 2 ] l u t [ 3 ] l u t [ 4 ] l u t [ 5 ] l u t [ 6 ] l u t [ 7 ] l u t [ 8 ] l u t [ 9 ] …”

Hardware spiking neural network with run-time reconfigurable connectivity in an autonomous robot

“…Furthermore the POEtic circuit has a dynamical routing mechanism through which connections betwen components can be built automatically and at run-time [20,27]. The dynamical routing can be launched by the logic elements, not only by an external controller.…”
