ADSP-TS101SAB1Z000

Digital Signal Processor Dsp Overview

The ADSP-TS101SAB1Z000 is a TigerSHARC static superscalar digital signal processor operating at 300 MHz with a 3.3 ns instruction cycle. It features dual computation blocks supporting up to four instructions per cycle, delivering 1800 MFLOPS or 7.3 GOPS performance. The device integrates 6 Mbits of on-chip SRAM divided into three 2M-bit banks (M0, M1, M2), providing 14.4 GB/s internal bandwidth. Key peripherals include a 14-channel DMA controller, four link ports, an external port for host/memory interfacing, and an SDRAM controller. It supports 32/40-bit floating-point and 8/16/32/64-bit fixed-point processing within a 484-ball CSP_BGA package.

Digital Signal Processor Dsp Feature Summary

• Static Superscalar architecture executing up to four 32-bit instructions per cycle via dual compute blocks.
• 6 Mbits of on-chip SRAM organized in three independent 2M-bit memory banks for simultaneous access.
• Integrated I/O subsystem including 14-channel DMA, four link ports, external port, and SDRAM controller.
• Supports multiprocessing systems of up to eight processors with on-chip arbitration and glueless interconnection.

Digital Signal Processor Dsp Applications

• Telecommunications infrastructure requiring high-performance DSP algorithms.
• Large-scale multiprocessor DSP applications with low communication overhead.
• Signal processing tasks involving complex correlations and trellis decoding (e.g., Viterbi/turbo decoders).

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix Z000 against the manufacturer's current ordering guide to confirm package type and temperature range. Confirm RoHS compliance status as specifications are subject to change. Ensure ESD precautions are observed during handling due to moisture sensitivity classification.

Digital Signal Processor Dsp Selection Notes

Select this component when system requirements demand high throughput for floating-point or fixed-point operations exceeding standard DSP capabilities. The integrated SDRAM controller and extensive on-chip memory reduce external component count. Evaluate programming complexity due to the static superscalar architecture requiring explicit instruction parallelism management by the developer.

Digital Signal Processor Dsp Part Context

The ADSP-TS101S belongs to the TigerSHARC family of embedded processors from Analog Devices. It is code-compatible with other TigerSHARC processors such as the ADSP-TS201S and ADSP-TS202S. The AB1Z000 designation indicates a specific package and speed grade variant within the broader ADSP-TS101S product line.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in the provided documentation. Code compatibility exists with other TigerSHARC models like the ADSP-TS201S, but physical package differences (e.g., BGA-625 vs CSP_BGA) require PCB redesign. Verify electrical characteristics and timing parameters before substituting with similar high-performance DSPs.

Digital Signal Processor Dsp FAQ

What is the maximum number of TigerSHARC processors supported in a single bus system?

The ADSP-TS101S supports multiprocessing systems with up to eight TigerSHARC processors connected on a common bus using on-chip arbitration.

How does the ADSP-TS101S handle data alignment for non-aligned loads?

The Data Alignment Buffer (DAB) acts as a quad-word FIFO that enables loading of quad-word data from non-aligned addresses, improving efficiency for applications like FIR filters.

What interfaces are available for booting the processor?

The processor can be configured to boot from an external 8-bit EPROM at reset. The boot process uses DMA Channel 0 to load the program from the EPROM into internal memory.
