The Pace-Setting Performance and Features of the 56F8300 Hybrid Controllers
MOTOROLA Motorola 56F8300 Hybrid Controller Family 33
Figure 1-20. PE Software Abstraction Layers
The software that PE generates according to your graphical configuration are either at the Processor
Expert System Library (PESL) level or the Embedded Bean (EB) level. The PESL level is highly
efficient and simple, but it is at a low level and provides a low level of abstraction from the hardware
as well as a low level of fictionalizing. Using the PESL software requires a greater degree of
knowledge of the component peripherals and the application is generally less portable across
platforms.
The EB level is at a higher level that provides much more functionality and a high level of abstraction.
Using embedded beans doesn’t require nearly as much knowledge of the underlying hardware and
provides for much improved portability of code across platforms. Where the PESL level is closely tied
to on-board peripherals, the EB level provides for both peripheral drivers and an extensive set of
application, I/O, and signal processing libraries.
In any given application PESL, EB, or both, can be used. Motorola’s Demo boards and EVM kits
include reference applications using PE to further aid in the rapid development of end applications.
Figure 1-21 illustrates an example using PC Master Software to digitally probe signals internal to the
software operating on the 56F8300 device. The application is run in real time and the data is
exchanged in real time from the 56F8300 processor to the oscilloscope display function in the PC
Master Software running on the Windows host computer. Some of the features of the PC Master
Software are:
• Real time data capture
• Real time data logging
• Command and status exchange
• Real time graphical analysis
• Graphical environment
• Visual Basic Script or Java Script can be used for control of target board
• Easy-to-understand navigation
• Connection to target board is possible over a network, including the Internet
• Demo mode with password protection support
• Visualization of real-time data in Scope window
