Technische Universität München Compute Tile: Distributed Memory • OpenRISC Core – OR1200 (old) – mor1kx (new) • Extended for multicore – core identifjer SPR – Compare-and-Swap (CAS) unit (memory mapped) – scratch memory for each core • Shared memory (with L2$) version currently under development Philipp Wagner 17 OpTiMSoC @ FOSDEM 2014

Technische Universität München Network Adapter • Computation ↔ Communication • DMA Engine Bus – Transfer bulk data between tiles IRQ • Message Passing (MP) read write – Explicit communication between tiles – Asynchronous T o NoC From NoC Philipp Wagner 18 OpTiMSoC @ FOSDEM 2014

Technische Universität München Memory Tile On-Chip SRAM or External DDR Memory Philipp Wagner 19 OpTiMSoC @ FOSDEM 2014

Technische Universität München I/O Tiles • UART • SPI • LCD dotmatrix display Philipp Wagner 20 OpTiMSoC @ FOSDEM 2014

Technische Universität München Accelerator Tiles • For CPU offoad • Needs to handle NoC protocol and possibly Message Passing protocol • currently working on AES (crypto) tile Philipp Wagner 21 OpTiMSoC @ FOSDEM 2014

Technische Universität München Network-on-Chip: LISNoC • Basic NoC implementation – mesh or ring – wormhole – packet switched – dimension routing – confjgurable buffers – virtual channel support • Other features “available on request” (bufferless, multicast, ...)

Technische Universität München T arget Platforms RTL Simulation FPGA Emulation Philipp Wagner 24 OpTiMSoC @ FOSDEM 2014

Technische Universität München T arget: RTL Simulation • ModelSim – signal-level insight into HW – short turnaround times – rather slow • Verilator – great for system-level and software development – much faster than ModelSim – free software! • Icarus Verilog – free software – never tested Philipp Wagner 25 OpTiMSoC @ FOSDEM 2014

Technische Universität München T arget: FPGA ZTEX USB-FPGA 1.15b/d Xilinx University Program Virtex 5 Xilinx Spartan 6 FPGA and (XUPV5; almost ML505) Cypress FX2 USB 2.0 pro: fast, real hardware con: hard-ware = hard bugs Philipp Wagner 26 OpTiMSoC @ FOSDEM 2014

Technische Universität München Programming? ? Philipp Wagner 28 OpTiMSoC @ FOSDEM 2014

Technische Universität München Programming: the basics • newlib C library port • OpenRISC GCC Philipp Wagner 29 OpTiMSoC @ FOSDEM 2014

Technische Universität München Programming: “Operating System” • libbaremetal : drivers, utility functions – Mutex, CAS, interrupt handling, DMA, timer • libruntime : simple runtime system – scheduler, thread handling • Multicore Association Communication (MCAPI) and Task Management API (MTAPI) – message passing (MCAPI) and heterogeneous task management (MTAPI) APIs • Linux support is being worked on, ETA end of 2014 Philipp Wagner 30 OpTiMSoC @ FOSDEM 2014

Technische Universität München Programming: Hello World $> cat hello_simple.c #include <stdio.h> void main() { printf("Hello World!\n"); } $> cat Makefile PROGRAM=hello_simple BUILDSCRIPTS=$(shell pkg-config --variable=buildscriptdir optimsoc-baremetal) include $(BUILDSCRIPTS)/Makefile.inc All build infrastructure is included! Philipp Wagner 31 OpTiMSoC @ FOSDEM 2014

Technische Universität München Debugging: Concept • tracing only • hardware support – fjltering, compression – no interference with system • debug modules in hardware – instruction traces – software traces • printf() • send events from software – NoC status • initialization of memories Philipp Wagner 32 OpTiMSoC @ FOSDEM 2014

Technische Universität München Debugging: Implementation Philipp Wagner 33 OpTiMSoC @ FOSDEM 2014

Technische Universität München What can I use OpTiMSoC for? • Use your FPGA: Build your own SoC – often 1 or 2 CPU cores are enough • Develop/evaluate hardware architectures/extensions • Look inside a SoC • <insert your ideas here> Philipp Wagner 37 OpTiMSoC @ FOSDEM 2014
