PROPELLER SPIN BRAIN PART 2
"The Spinning Brain"
Continuing with our previous edition about the Spin Brain, we will look at five Parallax Propeller chips connected together to make a new type of processing machine, examining more elements and specs about this cute little machine.
In this Edition of The Spinning Brain, we will cover

CHIP INVENTORY
Five chips provide for the following useful elements of functional inventory:
5 Chip Inventory
* Five AI individuals (5 chips)
* 40 Deterministic Cores (5x8 Cogs)
* 160 GPIO Pins (5x32)
* 160K RAM (5x32K)
* 160K ROM (5x32)
* 80 Counters (5x16)
* 40 Video Generators (5x8)
* 13,600 MIPS (5x2720 Theoretical)*
* 160 Hard Processors (5x32)
* 5,000 Vprocessors (5x1,000)
* 5,160 Total Processors (5,000+160)
* SPIN, PASM Programming Languages
PROCESSORS
Each Cog is a RISC processor and each chip has eight. Each counter is a processor with exactly one instruction: a conditional ADD. A chip has 16 counters. Each video generator is a processor with one instruction: a Shift by one or two. A chip has eight video generators.
Processors per Chip
08 Cogs
16 Counters
08 Video Generators
32 Total Processors per chip
MIPS - Millions instructions per second
DFLOP - D stands for ten (DECA)
HFLOP - H stands for hundred (HECTO)
KFLOP - K stands for thousand (KILO)
MFLOP - M stands for million (MEGA)
GFLOP - G stands for billion (GIGA)
TFLOP - T stands for trillion (TERA)
13,600 MIPs is 13,600,000,000 IPS or 13.6 billion instructions per second, related to 13.6 GFLOPs. In going from 5 chips to 100: 20x13.6=272 GFLOPS.*
* Note this is a relative theoretical comparison from one Propeller chip to a series of Propellers within the contextual definitions we have established for one chip, and is not intended as a comparison to other machines with other designs.
