New Features New Block Library for C6416 DSK Target The blocks in the C64x DSP Library correspond to assembly-code routines in the Texas Instruments TMS320C64x DSP library, which target the TI C64x family of digital signal processors. You use these blocks to develop simulations by building models in Simulink before generating code. Once you have a model developed, you can invoke the Real-Time Workshop to generate code that is optimized to run on the C6416 DSK.

PAGE 21
New Features New Options to Enable RTDX The To RTDX and From RTDX blocks include a new feature that lets you enable the RTDX channels defined by the blocks in your models. When you add RTDX blocks to your model, you enable the associated channels by selecting the Enable RTDX option when you configure the block. When you generate code from the model, the generation process dynamically sets the buffer sizes for the channels.

3 Embedded Target for TI C6000 DSP 1.0 Release Notes Note that the interrupt scheduler assumes that the signal processor clock is running at 100 MHz for the C6701 EVM target or 150 MHz for the C6711 DSK target. If the clock rate does not match the assumed rate, the sample rates in your model will be incorrect and your model will generate incorrect results.
PAGE 37
New Features interrupt rate = DSP clock rate/Sine block sample rate = 100 MHz/1KHz = 100 KHz yielding a sample period of 10 µsec, one interrupt sent to the sine wave generator every 100000 clock cycles. If your actual clock rate on your C6701 EVM has been reset to 150 MHz, the 10 µsec period is wrong and the sine wave is generated incorrectly. Inline DSP Blockset Functions Option Added Code generated from blocks in DSP Blockset use functions in a static run-time library.
