= Cell Broadband Engine =

The Cell CPU has one 3.2Ghz PPE (Power Processor Element) with two threads and eight 3.2Ghz SPE (Synergistic Processing Elements).

The PPE is a general purpose CPU, while the eight SPE are geared towards processing data in parallel. One SPE is disabled to increase yield, so the PS3 can have at most 9 threads running at the same time (2 from PPE and 7 from SPE). Note that one SPE is reserved for the hypervisor, so PS3 programs can take advantage of 8 threads. Both the PPE and SPE of the Cell are 64 bit, and manipulate data in Big Endian.

== Specifications ==

* 1 PPE (Power Processor Element)
** 3.2Ghz
** 64 bit, Big Endian
** 2 threads (can run at same time)
** L1 cache: 32kB data + 32kB instruction
** L2 cache: 512kB
** Memory bus width: 64bit (serial)
** VMX (Altivec) instruction set support
** Full IEEE-754 compliant 
** the PPU can execute two double precision or eight single precision operations per clockcycle
* 8 SPE (Synergistic Processing Element)
** 3.2Ghz
** 64 bit, Big Endian
** 1 SPE disabled to improve chip yield (see: [[Unlocking the 8th SPE]])
** 1 SPE dedicated for hypervisor security
** 256KB local store per SPE
** 128 registers per SPE
** Dual Issue (Each SPE can execute 2 instructions per clock)
** IEEE-754 compliant in double precision (single precision round-towards-zero instead of round-towards-even)

There is a lot of info about CELL/BE on the [[Cell Programming IBM]] page.

'''Note:''' All Cell BE packages measures 42.5mm × 42.5mm

The Cell BE was introduced at 90nm. Later, PS3 model numbers starting with CECHG uses the 65nm version, while the PS3 Slim (CECH-20xx) used the 45nm version (See [[SKU Models]] and table below).

== PVR (powerpc version register) ==
The PVR inside the microprocessor is the only way to identify what version of what part you have.

 cat /proc/cpuinfo

or

   unsigned int pvr;
   __asm__ __volatile__ ("mfpvr %0" : "=r" (pvr));

code above should work in kernel & user mode. <!-- http://lists.freebsd.org/pipermail/svn-src-head/2010-February/014780.html -->

== Unsorted ==
=== Cell Integrated Heat Spreader (IHS) WARNING ===
Starting with PS3 Slim models CECH-25xx some of the CELL Integrated Heat Spreaders are secured to the CELL processor die with thermal adhesive. Cell processor models with a thinner substrate and black plastic spacer in between the IHS and the substrate may be glued. Removing an IHS that is glued to the Cell will destroy the Cell CPU.

=== IHS size and mounting ===
on a COK-001 the CPU heatspreader is 4.00cm x 4.00cm while the RSX heatspreader is 4.25cm x 4.25 cm - CPU and RSX mountholes are 8.75cm apart and 6.3mm diameter

although a PC cooler should fit within these dimensions fine, mounting the 2 (which are also elevated differently from the motherboard) can be problematic
