Open Source Finally Hits Real Silicon
pagercam2 writes "While Open Source software has many success stories, hardware and particularly chips haven't had as much. While there have been multiple Open Source projects, none have come to a final product until now. The OpenRISC 1000 has been implemented by Flextronics Semiconductor(a division of Flextronics, the contract manufacturer possibly best known for its production of many Cisco products) along with PCI, 10/100 Ethernet, serial, GPIO etc. ... Details and pretty pictures available at OpenCores.org, and it even runs uClinux. Good Job!"
So what's Sparc V? Swiss Cheese? Sparc specs have been available for a LONG time.
Javascript + Nintendo DSi = DSiCade
This is indeed a good step for the Opencores project, but the subject itself is misleading.
The LGPL'd SPARC-compatible processor Leon was put to silicon a long while ago.
Give credit where credit is due, the Leon tracked over this territory years before OpenRISC.
Karma Whoring for Fun and Profit.

Flextronics would actually be best known for being the main manufacter of the Microsoft Xbox.

Project: OpenRISC 1000
Silicon Implementations
Several companies are making silicon implementations (ASICs) of OR1200 using different library vendors and foundaries, process geometries from 0.35um to 0.13um. For references contact lampret@opencores.org.
Here is an example of System-On-Chip (SOC) from Flextronics Semiconductor. It is a 32-bit general-purpose microcontroller implemented on UMC 0.18um targetting embedded applications with maximum clock frequency of 160MHz. The SOC features:
* OR1200 processor
* Memory Controller (FLASH, SDRAM, SRAM, DPRAM)
* PCI 2.2 32-bit interface 33/66MHz
* Ethernet MAC 10/100
* UART16550
* GPIO
* JTAG/Debug Interface
The OR1200 is implemented with 8KB instruction and 8KB data caches, I/DMMU with 64 TLB entries each, power management unit, debug unit, tick timer and interrupt controller. Its 32x32 multiplier is coupled with a 64-bit MAC unit.
Test board for testing the SOC has 64MBytes of SDRAM, 32MBytes of FLASH, RS232 transceiver, Ethernet 10/100 PHY. Connectors are for RS232, Ethernet, JTAG/Debug and several Mictor logic analyzer connectors. The board has its own DC/DC regulators for 3.3V IO power supply and 1.8V core power supply. It can be used as stand alone board or as PCI standard form plugin board.
Software running on the SOC is Embedded Microcontroller Linux (uClinux) with a console on serial RS232. The console shows a network ping to a local network host - the ping shows the Ethernet 10/100 capability.
This board was the first prototype built (not fully assembled at the time)
Dynamic power of the entire test board is 1.4W. Dynamic current of the SOC IO power supply is 52mA (3.3V) and dynamic current of the SOC Core power supply is 86mA (1.8V). These are nominal values measured at 100MHz system clock.
Maximum system clock frequency of the SOC is 160 MHz. System clock is used to clock not only the OR1200 processor but the entire chip (exception is memory controller which can also run at 1/2 system clock). Max system clock 160MHz was obtained at 25C ambient temperature, 3.3V IO and 1.8V core.
Test boards are available to Flextronics Semiconductor ASIC customers. For more information about the test boards, the SOC technical details and business engagement please contact Flextronics Semiconductor.
IMPORTANT NOTE: For a live demonstration of the SOC in Silicon Valley, California during Dec 8th 2003 and Dec 15th please contact Damjan Lampret.

Chas - The one, the only.
THANK GOD!!!
"Can anyone seriously point out some practical applications of this processor?"
Sure.
For chips derived from this test SoC:
MP3player
VoIP hard phone
Network Router
Firewall
Wireless Access Point
DVD player
Car stereo
Cell Phone
PDA
For uClinux:
It's all around you, many of the products _you_ use every day run it. Just because you think Linux means servers and desktops doesn't mean that's the only place it's widely deployed!

Just FYI, this guy's a troll. Check out his recent posts. Apparently he's also "in middle management at Honda". I highly doubt Apple are considering OpenRISC for the iPod.
Bad troll. Bad.
Sailing over the event horizon
Sure it could be done, up to and including the design verification using chip simulations, but actually making the chips and debugging the silicon process could get very expensive. I'm sure you could find a foundry in Taiwan or China to produce it, but would there be a market for it so you could get back all those startup costs? Do you know of some folks who have a few hundred K to invest against AMD, Intel, Motorola and IBM for a tiny slice of the market? Hardware has a lot of startup costs than software to get it to market. It's not like compiling the new code for your kernal fix. Maybe if it was specialized and optimized for embedded applications it might have a shot. I guess you could call it the "Penguin" chip since I'm assuming it would be optimized for Linux.
