Frequently Asked Questions
At what clock speed does TMS320C6655CZH operate, and how does this translate to signal processing throughput?
TMS320C6655CZH operates at up to 1000 MHz with a 32-bit fixed and floating-point DSP core capable of executing multiple multiply-accumulate operations per cycle, delivering peak performance exceeding 8 GFLOPS for FFT, FIR filter, and radar range-Doppler processing.
Does TMS320C6655CZH support both fixed-point and floating-point arithmetic, and what algorithms benefit from this dual capability?
TMS320C6655CZH supports both 32-bit fixed-point and IEEE 754 floating-point arithmetic, enabling algorithms like FFT, OFDM demodulation, and neural network inference to use 32-bit floating-point for dynamic range while fixed-point operations handle 16-bit audio and control loops efficiently.
What memory interface does TMS320C6655CZH provide, and what external memory configurations are supported?
TMS320C6655CZH provides a 16-bit external data bus with a 24-bit address bus, supporting up to 16 MB of external SDRAM or SRAM alongside integrated L1 and L2 cache hierarchy, which buffers sample data, FFT twiddle factors, and filter coefficient tables for sustained 1 GSPS data throughput.
How does TMS320C6655CZH's JTAG boundary scan support production test compared to DSPs without this feature?
TMS320C6655CZH's IEEE 1149.1 JTAG boundary scan allows automated test equipment to verify all 400+ I/O signal connections without functional operation, reducing production test fixture cost by up to 40% in high-volume telecom board manufacturing and enabling in-circuit debugging of complex BGA assemblies.
