1.Power - Related Pins
VCC (Core Power): This pin supplies the core voltage to the DSP. For the TMS32C6711DZDPA167, the typical core voltage is 1.26 V. A stable and clean core voltage is essential for the proper operation of the internal logic circuits of the DSP.
VDD (I/O Power): The I/O power pin provides power for the input/output circuitry of the DSP. The standard I/O voltage is 3.30 V. This voltage level is used to interface with external devices and ensure proper signal levels for input and output operations.
2.Clock Pins
CLKIN: This pin is used to connect an external clock source to the DSP. The external clock signal determines the operating frequency of the DSP, which in the case of TMS32C6711DZDPA167 is 167 MHz. A precise and stable clock signal is crucial for the accurate execution of instructions and the overall performance of the DSP.
3.Memory - Related Pins
EMIF Pins: These pins are associated with the External Memory Interface (EMIF). There are address pins (A[0:23]) that are used to address the external memory locations. Data pins (D[0:31]) are responsible for transferring data between the DSP and the external memory. Control pins such as WE# (Write Enable), OE# (Output Enable), and CE# (Chip Enable) are used to control the read and write operations to the external memory. For example, when the DSP needs to read data from an external SDRAM, the appropriate address is sent through the address pins, the OE# pin is activated to enable the output of data from the SDRAM, and the data is then transferred through the data pins.
With performance of up to 1200 million floating-point operations per second (MFLOPS) at a clock rate of 200 MHz or up to 1500 MFLOPS at a clock rate of 250 MHz, the C6711D device also offers cost-effective solutions to high-performance DSP programming challenges. The C6711D DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. This processor has 32 general-purpose registers of 32-bit word length and eight highly independent functional units. The eight functional units provide four floating-/fixed-point ALUs, two fixed-point ALUs, and two floating-/fixed-point multipliers. The C6711D can produce two MACs per cycle for a total of 400 MMACS.The C6711D DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals.
