LowCost multiprocessor cluster based on cheap ARM MCU Cortex - M3 (in phase 1.)
Goals of this project
Idea
Device will contains slaveNodes, masterNode, storageNodes, this device is superNode, this superNode contains:
slaveNodes - processors card
masterNode - controller for internal communication between slaveNodes and external communication between superNodes
storageNodes - card what have n. SD cards slots for storage, or SATA interfaces
slaveNode concept
each slaveNode have communication core and computing cores. Computing cores have one shared internal bus and access to dual port RAM. On other side DPRAM is communication core. This design allow use multiple design inside of slaveNode, cuz slaveNode is represented in superNode's internal bus by communication core. Then we can put on the slaveNode n. computing cores and doesn't matter if slaveNode have 4 computing cores or 128 cores or if computing cores have different architecture.
masterNode concept
masterNode is main controller for data interchange between slaveNodes (and superNodes, probably by ethernet interface (in future)).
Phases of project
Step #1
One slaveNode board have 8 computing ARMs LPC1343 and 1 communication core (same MCU). brmCarraba (superNode) have 6 this boards and 1 masterNode. Master node have 1 core with ehternet interface. masterNode control internal bus between nodes, ethernet output (for connecting superNodes), USB port, VGA output, port for handling small OLED dislay on case (enclosure), PS/2 keyboard. USB can be in HOST mode.

Four general purpose counter/timers
GPIO pins can be used as edge and level sensitive interrupt sources
Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8
MHz
Power-On Reset
Case for brmCarramba
i choose al box what have profile inside, cuz i will put in this box card like slaveNode and masterNode .. this box can contains 11 pcb. Now i can desing PCB cuz i know real allowed sice of this PCB. Size is 20x103x53mm.
