Workshop - November Toulouse Paul Brelet TRT Case of smart camera system 24/11/2011 1 Introduction Socket Flow. Hardware Design Flow. Tools: SPEAR DE MAGILLEM Tools GAUT 2Workshop - November 2011 SoCKET Flow Global SoC Req. SoC Architecture Functional validation SW Performance Validation C/C++/ASM Functionality Fonctionnalit + timing Instruction Set Simulator System Requirements Platform Assembly Metrics HLS System Properties Hardware properties Software properties TLM LT TLM AT Software Co-simulation/Co-emulation Silicon Software Execution HLS Traffic generator Metrics IP-Xact SoC Headers generation RTL Software Requirements traceability 3 Phase 2: HW Design Level: RTL. Tools: - GAUT: Apply on accelerator engines. - Magillem: Packager, Platform Assembly, Generator Studio. - SPEAR DE: Mapping Validation : Register Level.

VHDL code generation: - Using generics. - The code is readable by an individual. - Inter-connects are taken into account during the VHDL code generation. 13Workshop - November 2011 GAUT Tool The C code: - The C code must be very close to VHDL code. Comparison with commercial tools: - Roccc, ImpulseC. Some troubles during VHDL code generation: - The generated code can be synthesizable but it does not work well in placement/routing. 14Workshop - November 2011 IP-XACT Advantage Standard: Reuse strategy Support of SystemC Model by TLM ports Opportunities for bottom up and top down XML Transformation: correct and complete XML descriptions Hardware description: lot of data for several components 15Workshop - November 2011 Questions? 16Workshop - November 2011
