Make an SPE and Existing Code Work Together
Traditional porting requires identifying and abstracting out the architecture-dependent code. While this procedure works for getting code to run on the Cell/B.E. processor, to actually use the extra processing elements, you have to put in extra work. In this series, learn how to make an SPE and existing code work together, minimizing recording impact.

How Libspe2 affects Cell B.E. Programming
In this article, learn to do basic SPE process management and communication with libspe2. This standard library that PPE programs use to access and manage SPEs has undergone a major revision, and the Cell B.E. SDK2.1 makes the change from libspe1 to libspe2 official.

Communication with Mailboxes and Interrupts
Meet two more means of communication between the SPE and the
PPE -- mailboxes and signal notification. Mailboxes are
special-purpose registers, similar to the I/O registers used to
communicate with peripheral devices on some systems, while
signal notification registers are registers which can be read
or written to by the PPE, but which the SPE can only read.

DC Motor Controlling System
Now a days DC motors plays a vital role in most of the industrial areas, it can be seen in most of the electronic devices. Many methods evolved to control the revolution of a motor. DC motors can be controlled either by software or directly by hardware. Software controlling needs computers which are bulky and common man cannot afford for it, so hardware controls are in use. Even in hardware if it is programmable device then it is preferred because it can be modeled according to the requirements of the user.
