Figure 1. Key Features of the C5535 DSPShield
1.2 DSPShield Architecture
The C5535 DSP is a peripheral rich processor. However, to limit the pin count, the
C5535’s pins are heavily multiplexed. Depending on the application, the C5535 is
programmed with the appropriate internal peripherals routed to its external pins. The
DSPShield maintains this flexibility by using additional discrete multiplexers to connect
the C5535’s GPIO/peripheral pins to the appropriate points on the board. Additonal
flexibility can also be found in the power management for the board and in the
Arduino/DSPShield interface. The DSPShield block diagram is shown in Figure 2.
The DSPShield architecture consists of the following major blocks:
1. Power Management
2. The C5535 DSP and Internal Peripherals
3. DSPShield Peripherals
4. Arduino Interface
5. DSP Expansion Connector
6. XDS100-V2 Embedded Emulator
