Texas Instruments' model TMS320C5517AZCHA20 is a DSP digital signal processor, a member of TI's C5000™ fixed-point digital signal processor (DSP) product family, designed for low operating and standby power applications. This device generates a CPU processor core based on the TMS320C55x DSP. The C55x DSP architecture achieves high performance and low power consumption through increased parallelism and emphasis on energy conservation.
The CPU supports an internal bus structure that consists of a program bus, a 32-bit read bus and two 16-bit data read buses, two data write buses and additional buses dedicated to peripherals and DMA operations. These buses enable up to four 16-bit data reads and two 16-bit data writes in a single cycle. The device also contains four DMA controllers, each with 4 channels, providing 16 independent channels of data transfer without CPU intervention. Each DMA controller can perform one 32-bit data transfer per cycle, which is parallel to and independent of CPU operation.
The C55x CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit by 17-bit multiplication and 32-bit addition in a single cycle. A central 40-bit arithmetic and logic unit (ALU) is supported by an additional 16-bit ALU. Usage of the ALU is controlled by the instruction set, providing the ability to optimize parallel operation and power consumption. Address units (AU) and data units (DU) within the C55x CPU manage these resources.
C55x CPUs support a variable byte width instruction set to improve code density. The instruction unit (IU) performs instruction fetches from a 32-bit program in internal or external memory and queues instructions to the program unit (PU). The PU decodes instructions, directs tasks to address unit and data unit resources, and manages a fully protected pipeline. The jump prediction feature avoids pipeline flushing when conditional instructions are executed.
The GPIO functionality along with the 10-bit SAR ADC provides sufficient pins for status, interrupts, and bit I/O for keyboard and media interfaces. Serial media support is provided through the following devices: two multimedia cards and secure digital (MMC and SD) peripherals, three internal IC sound (I2S-bus) modules, a serial port interface (SPI) with four-chip select, A multi-channel buffered serial port interface (McSPI) with three chip select master and slave, a multi-channel serial port (McBSP), an I2C multi-master and slave interface, and a universal asynchronous receiver-transmitter (UART ) Interface The device's peripheral set includes an external memory interface (EMIF) that provides seamless access to asynchronous memories such as EPROM, NOR, NAND, and SRAM, as well as high-speed, high-density memories such as synchronous DRAM (SDRAM) and mobile SDRAM (mSDRAM).
Other peripherals include: a configurable 16-bit universal host port interface (UHPI), a high-speed universal serial bus (USB2.0) that only supports device mode, a real-time clock (RTC), three general-purpose timers (one Configurable as a watchdog timer) and an analog phase-locked loop (APLL) clock generator.
The TMS320C5517AZCHA20 also contains a tightly coupled FFT hardware accelerator - supporting 8 to 1024 points (powers of 2) real-valued and complex-valued FFTs, and three integrated low-dropout regulators (LDOs) - powering various parts of the device (requires external power supply Except for CVDDRTC): ANA_LDO provides 1.3V for the SAR and power management circuit (VDDA_ANA), DSP_LDO provides 1.3V or 1.05V for the DSP core (CVDD) (can be selected by software in real time once the operating frequency range is detected), USB_LDO provides 1.3V voltage for the USB core digital circuit (USB_VDD1P3) and PHY circuit (USB_VDDA1P3).
The TMS320C5517AZCHA20 is powered by the industry-acclaimed eXpressDSP™, Code Composer Studio™ integrated development environment (IDE), DSP/BIOS™, Texas Instruments (TI) algorithm standards and a large third-party network. Code generation tools provided by Code Composer Studio IDE include a C language compiler and linker, RTDX™, XDS100, XDS510™, XDS560™ emulated device drivers and evaluation modules. The device is also supported by the C55x DSP library and chip support library, which features more than 50 basic software cores (FIR filters, IIR filters, FFTs and various math functions).
