Hello World Programming on PS3

English / Japanese
There are several ways to write programs on PS3 using SPE. This page introduces some programs to realize the traditional “Hello World” on PS3.
Actually, the processing to write “Hello World” from SPE to a console is performed just by calling the function “printf()” in PPE from SPE. (All the I/O functions on SPE are internally sent to PPE and processed because SPE cannot directly access I/O.) Therefore, in fact, most of the computing capabilities of SPE are not used in the programs mentioned in this page. The key to fully utilizing the features of PS3 is that how you can perform parallel computations with SIMD operations or duplication of DMA transfer in addition to the normal operations of SPE.
However, frameworks of programs mentioned here will be helpful in understanding flows to run programs on SPE or in surveying the differences between libspe1 and libspe2.
See Overview of Libspe for the summary of libspe and Building Libspe Programming Environment for the details of building programming environment using libspe. Also, see Known Bugs for Libspe for the known bugs of libspe.
