How to add Performance and Flexibility to DSP systems?

• Nearly all systems are composed of:– Custom Logic + Memory + Processor + Bus + IP

• Enables optimum “system partitioning” between HW and SW• Customers “Embed it their way”

Performing some SW tasks

in HW can be expensivePerforming some HW tasks

in SW can be slow

Tune your system for the optimum Hardware/Software balance.

Expanding Hardware Design to include complete System

• Slower to adopt

embedded processing

– Lack of domain expertise

– Lack of clear understanding of benefits

– Misperception on FPGA area and performance effects


Increased Functionality

• Adding embedded processing to an FPGA design provides more flexibility and functionality

– Software interface to hardware

– Coefficient and table updates

– Additional configurations

– Status feedback

Software Interface to Hardware


Faster Design and Debug Iterations

Software Development Environment

• Rebuild software and update bitstream in a few minutes– Reload filter coefficients

– Update tables

– Configure operations

• Minimizes place and route iterations


Reducing BOM = Reduced Cost

• Reduce BOM costs by reducing chip count

• Replace processor and FPGA with an FPGA that includes processing

• Embedded system can be added for less than 1000 slices to an FPGA

Base System Builder Demo


Create DSP Accelerators in FPGAs using Simulink

• Extensive set of DSP building blocks optimized for Xilinx

• Interactive simulation capability to verify models at the block level– DSP signal sources

– DSP analysis, scope, plots

• MATLAB Integration

System Generator for DSP


Easily Integrate DSP Accelerators into Embedded Systems

• ISE Design Suite automates the integration of DSP accelerator blocks into embedded systems– Creates hardware interface to FSL or PLB bus

• Synchronous or asynchronous

– Creates software driver files

Save Time through Tool Automation

• System Generator automatically generates DSP accelerators for use with the Xilinx embedded development environment (XPS)– placed into embedded IP Catalog

– Supports PLB or FSL bus

– Supports async clocking

– Includes driver files and documentation

• XPS project can be imported into SysGen for system debug


Abstracting the Processor Interface

• “Shared” registers, RAMs and FIFOs are used to create HW / SW abstraction

– DSP design connects to a “to”or “from” memory

– Memory maps and interface logic is added during RTL generation

– Software drivers and documentation are created for easy programming
