BelaSigna 200
5.0 Development Tools
5.1 Evaluation and Development Kit (EDK)
BelaSigna 200 is supported by a set of development tools included in the evaluation and development kit (EDK).
The EDK is intended for use by DSP software developers and hardware systems integrators. It consists of the following components:
• Hardware
•
BelaSigna 200 evaluation and development board (contains BelaSigna 200 device)
• Software
•
•
•
•
•
•
•
•
•
Complete assembly tool chain (assembler, linker, librarian, etc.)
Low-level hardware-specific libraries
Basic algorithm toolkit (BAT)
Basic operating system libraries (BOS)
WOLA windows and microcode
Real-time debugger
EEPROM file system manager
UltraEdit IDE
WOLA toolbox for Matlab for rapid application development and prototyping
BAT and BOS provide all the common processing routines in an easy-to-call macro structure. This streamlines the assembly level
coding by encapsulating redundant work, while maintaining the true efficiency of hardware-level coding.
For advanced DSP developers or application developers, ON Semiconductor provides an application development extension to the
EDK, which contains the following:
• Python language installer (version 2.2)
• The wxPython GUI toolkit
• Embedding toolkit (used to build standalone Python applications)
• ON Semiconductor extension
•
•
•
•
Python interface (pyLLCOM) to ON Semiconductor’s low-level communications library (LLCOM)
File I/O library (supports standard ON Semiconductor file formats)
EEPROM access library
DSH (ON Semiconductor Python Shell – standard command-line shell with customizations for BelaSigna 200)
5.2 BelaSigna 200 Rapid Prototyping Module
The rapid prototyping module (RPM) is fast and easy for designers to integrate with existing and future products that are not yet DSP-
enabled. It also allows for the quick implementation of field trials and rapid prototyping to evaluate the benefits of BelaSigna 200. The
RPM features BelaSigna 200 along with a 256-Kbit EEPROM for storing a variety of custom algorithms. On-board power regulation
circuitry allows the RPM to run off a wide variety of power supplies. A fast oscillator (included on the RPM) running at 24.576MHz
provides a choice of many sampling frequencies and can be enabled for when heavy-duty signal processing is required.
5.3 BelaSigna 200 Demonstrator
The BelaSigna 200 demonstrator lets device manufacturers quickly and easily assess the speech- and audio-centric benefits delivered
by BelaSigna 200 in a full-featured, self-contained portable unit. The demonstrator is housed in a durable, portable, lightweight package
complete with belt clip to facilitate demonstrations in the field. This tool can be easily utilized in real world scenarios to experience the
benefits of noise reduction, signal enhancement and a variety of other algorithms. The demonstrator can be connected to a wired
headset and function like a dongle to communicate with a Bluetooth mobile phone.
