Analog Devices Inc. ADSP-TS101SAB1-100

Overview

ADSP-TS101SAB1-100 from Analog Devices is a 300 MHz Static Superscalar DSP processor with dual computation blocks, 6 Mbits of on-chip SRAM (3 × 2M-bit banks), and integrated SDRAM controller, designed for high-throughput telecommunications infrastructure and multiprocessor signal processing systems.

For engineers reviewing the ADSP-TS101SAB1-100 datasheet, ADSP-TS101SAB1-100 pinout, ADSP-TS101SAB1-100 application, or ADSP-TS101SAB1-100 equivalent, key selection criteria include instruction cycle time (3.3 ns), internal memory bandwidth (14.4 GB/s), SIMD-capable compute architecture, IEEE 1149.1 JTAG support, and glueless multiprocessing capability for up to eight processors.

Technical Context

The ADSP-TS101SAB1-100 implements a Static Superscalar architecture executing up to four 32-bit instructions per cycle via dual compute blocks (X/Y), each with ALU, multiplier, 64-bit shifter, and 32-word register file. It features three independent 128-bit internal data buses connected to separate 2M-bit SRAM banks.

It integrates a 14-channel DMA controller supporting flyby, chaining, and 2D transfers; four link ports (250 MB/s each); dual integer ALUs with circular buffer and bit-reverse addressing; and an SDRAM controller supporting 32/64-bit interfaces with standard 16–256M-bit SDRAMs.

FAQ

What is the maximum sustained computational throughput of the ADSP-TS101SAB1-100?

The ADSP-TS101SAB1-100 delivers 7.1 GOPS for 16-bit fixed-point operations and 1.8 GOPS for 32-bit fixed-point operations under sustained load, based on FIR benchmark results showing 7,200 cycles for 50-tap filtering on 1024 inputs at 300 MHz. Its dual compute blocks and three 128-bit internal buses enable this throughput without memory bottlenecks.

Does the ADSP-TS101SAB1-100 support IEEE 1149.1 JTAG debugging?

Yes, the ADSP-TS101SAB1-100 includes a fully compliant IEEE 1149.1 JTAG test access port for boundary scan, on-chip emulation, and real-time debugging. Pins TRST, TCK, TMS, TDI, and TDO are dedicated to this interface and operate independently of core execution, enabling non-intrusive probeless development.

Can the ADSP-TS101SAB1-100 interface directly with standard SDRAM chips?

Yes, the ADSP-TS101SAB1-100 integrates a glueless SDRAM controller supporting 16M–256M-bit standard SDRAMs (e.g., Micron MT48LC16M16A2) via dedicated SCLK_P/SCLK_N, RAS/CAS, and DQM pins. It handles all timing, refresh, and bank management autonomously with no external logic required.

How many processors can be connected in a glueless multiprocessor configuration using the ADSP-TS101SAB1-100?

The ADSP-TS101SAB1-100 supports glueless multiprocessing with up to eight TigerSHARC processors on a shared bus, enabled by on-chip distributed arbitration logic and rotating priority bus access. This configuration requires no external glue logic and maintains full cache-coherent memory access across all nodes.

What type of memory architecture does the ADSP-TS101SAB1-100 use for its on-chip storage?

The ADSP-TS101SAB1-100 uses a unified, partitionable SRAM architecture with three independent 2M-bit banks (M0, M1, M2), each connected to its own 128-bit internal data bus. This allows concurrent instruction fetch from one bank while performing dual-data accesses from the other two, delivering 14.4 GB/s aggregate bandwidth.
