Texas Instruments TMS320C5535 Fixed-Point DSPs

Texas Instruments TMS320C5532, TMS320C5533, TMS320C5534, and TMS320C5535 Fixed-Point Digital Signal Processors (DSPs) are designed for low-power applications and based on the TMS320C55x DSPC55x DSP generation CPU processor core. The architecture achieves high performance and low power through increased parallelism and total focus on power savings. TI TMS320C553x DSPs support an internal bus structure composed of one program bus, one 32-bit data read bus and two 16-bit data read buses, two 16-bit data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to four 16-bit data reads and two 16-bit data writes in a single cycle. The device also includes four DMA controllers, each with 4 channels, providing data movement for 16-independent channel contexts without CPU intervention. The general-purpose input and output functions along with the 10-bit SAR ADC on the TMS320C5535 provide sufficient pins for status interrupts, and bit I/O for LCD displays, keyboards, and media interfaces. The TI TMS320C5535 DSP included a tightly-coupled FFT Hardware Accelerator. The tightly-coupled FFT Hardware Accelerator supports 8 to 1024-point (in power of 2) real and complex-valued FFTs.

TI TMDX5535EZDSP USB Stick Development Kit

The TI TMDX5535eZdsp is a small form factor, very low cost USB-powered DSP development kit which includes all the hardware and software needed to evaluate the C553x generation, which is the industry's lowest-cost and lowest power 16-bit DSP. This ultra-low-cost TI kit allows quick and easy evaluation of the advanced capabilities of the C5535. The TMDX5535eZdsp kit has an on-board XDS100 emulator for full course-level debug capability and supports Code Composer Studio™ (CCStudio) Integrated Development Environment (IDE) version 4.x and eXpressDSP™ software which includes the DSP/BIOS™ kernel. The full contents of the Development Kit include C5535 ezdsp board, CCStudio IDE Rev. 4.x, and headphone with mic, a 2-GB micro SD card, a free software framework for USB audio class and human interface device (HID) applications and an out-of-the-box comprehensive demo for USB audio class applications.
