[linux-elitists] Monday 15 Dec: first all-Open Source System-on-Chip
Thu Dec 11 09:15:07 PST 2003
Who: OpenCores developer Damjan Lampret
What: first public demonstration of an all-Open Source
Where: Freedom Technology Center
When: Monday, December 15, at 7pm,
Why: Open Source hardware designs are bringing new cost
savings and freedom to the semiconductor industry
On Monday, December 15, at 7pm, OpenCores developer Damjan
Lampret will give the first public demonstration of an
all-Open Source System-On-Chip (SoC) at the Freedom Technology
Center in Mountain View, California, USA. The new OpenCores
System-On-Chip, developed and manufactured by Flextronics
Semiconductor, runs Linux, uClinux, or eCos. The SoC is
exclusively built with freely licensed OpenCores IP cores.
The chip includes the OpenRISC OR1200 32-bit processor, a Memory
Controller for SDRAM/FLASH/SRAM, a 10/100 Mbps Ethernet MAC,
32-bit, 33/66MHz PCI support, and a 16550 UART.
Lampret said, "Are open source soft cores starting to have impact
on the semiconductor industry? Yes, slowly but irreversibly. What
started in 1983 with the GNU project is now starting in open source
hardware with OpenCores, 20 years later."
The demonstration will cover the System-On-Chip, how it
was designed and the manufacturing technology used. Special
attention will be paid to the processor, the OpenRISC. It
is a completely new RISC architecture developed using open
source model. The GNU Compiler Collection (gcc) was ported,
along with the GNU Binary Utilities including the assembler,
linker, and debugger. An advanced simulator was built that can
simulate now only the processor but an entire SoC, and of course
a complete synthesizable RTL implementation was developed. A
live presentation will show how the GNU development tools gdb
and DDD can be used to download software code and debug it on
The OpenRISC OR1200 has a memory management unit (MMU), so
can run either conventional Linux, which requires an MMU,
or uClinux, which is intended for processors without an MMU.
