Brain Memory Part 1


In the Parallax Propeller SPIN language scenario, a single chip's external EEPROM holds a 32K program. (One Propeller chip holds 32K RAM which is shared by all 8 processors.) The code transfers into the chip's 32K, which is also used for variables. In the Big Brain, this cloned code is multiplied by 100 times in the first two arrays, for 3,200K RAM of program code. A reset initiates transfer of 32K from the EEPROM into the chip-RAM in all chips and programs begin execution in each chip. Depending on programs, self modification can take place and evolution results.
