Starting VisualDSP++ and Connecting to the EZ-KIT Lite
1-4 Getting Started with ADSP-BF548 EZ-KIT Lite
• EZ-KIT Lite. This is the dedicated USB connection between the
PC and EZ-KIT Lite. The connection is simple to manage and is
an integral part of the EZ-KIT Lite. However, the connection is
available with the EZ-KIT Lite only. Once your custom hardware
board is available for development, you will use an emulator session
(description follows) to connect to the custom hardware.
• Simulator. This is a software model of the processor. Simulators
offer unique advantages, the first being that no external hardware is
required, a great benefit when using VisualDSP++ on the road.
Furthermore, simulators offer a deep insight to the internal work-
ings of the processor (pipelines, caches, and more), which is not
possible with hardware-based sessions. The downside is that a sim-
ulator is several orders of magnitude slower than actual hardware.
The software model simulates only the processor, making it diffi-
cult to accurately simulate a complex system that involves more
than the processor.
VisualDSP++ includes two types of Blackfin simulators: a
cycle-accurate, interpreted simulator and a functional, compiled
simulator. A cycle-accurate simulator is a completely accurate
model of the Blackfin processor and allows you to fully visualize
the inner-workings of the processor. The compiled simulator sacri-
fices the detailed view but allows you to simulate much more
quickly, at millions of simulated cycles per second depending on
the speed of your PC.
• Emulator. This is a JTAG emulator, the ideal device for connect-
ing to hardware, giving the best performance and maximum
flexibility. An emulator is a separate module that provides a
