FAQ

What is the maximum sustained floating-point performance of the ADSP-21062LKS-133?

The ADSP-21062LKS-133 delivers 80 MFLOPS sustained floating-point performance under real-world workloads, achieved through parallel ALU/multiplier/shifter execution, dual-ported memory access, and zero-overhead looping. This value reflects measured throughput in benchmarked FIR and FFT routines-not theoretical peak-ensuring predictable timing in production audio and radar systems using the ADSP-21062LKS-133.

Does the ADSP-21062LKS-133 support JTAG-based in-circuit emulation without halting real-time operation?

Yes, the ADSP-21062LKS-133 implements IEEE 1149.1 JTAG Test Access Port with non-intrusive boundary-scan and on-chip emulation capabilities. Debug operations such as breakpoint setting and register inspection occur during controlled halt states, but once resumed, the ADSP-21062LKS-133 executes at full 40 MHz with zero timing impact - critical for validating real-time audio or motor control loops.

How does the dual-ported SRAM in the ADSP-21062LKS-133 improve real-time signal processing efficiency?

The 2 Mbit dual-ported SRAM in the ADSP-21062LKS-133 consists of two independent 1 Mbit blocks, each accessible simultaneously by the core processor and DMA controller. This eliminates memory contention during concurrent instruction fetch, data processing, and background data movement - enabling deterministic execution of time-critical algorithms like FFT-based spectral analysis without pipeline stalls in the ADSP-21062LKS-133.

Can the ADSP-21062LKS-133 interface directly with a 32-bit microcontroller host processor?

Yes, the ADSP-21062LKS-133 features a memory-mapped host processor interface supporting both 16-bit and 32-bit asynchronous buses. A 32-bit host can directly read/write the ADSP-21062LKS-133's internal SRAM and IOP registers using standard address/data strobes, enabling seamless co-processor integration in systems where the host handles system control while the ADSP-21062LKS-133 manages real-time signal processing.

What is the function of the six link ports on the ADSP-21062LKS-133, and what throughput do they provide?

The six 4-bit link ports on the ADSP-21062LKS-133 provide point-to-point, low-latency interprocessor communication for multiprocessing configurations. Each port transfers 8 bits per core cycle (2× clock rate), delivering an aggregate throughput of 240 MBps across all six ports - enabling synchronized data exchange in radar beamforming arrays and distributed audio processing systems built around multiple ADSP-21062LKS-133 devices.
