transactional memory [2 Articles]
Jan Gray - Feb 13 2007
My friends, the big action these days in loveable programming models for
shared memory synchronization is transactional memory.

exclusive access RAM [6 Articles]
Rob Finch - Feb 11 2007
Have you ever looked at code guarded by mutexes and semaphores and
wondered, "what if the guarded code were placed in a RAM block that
ensured exclusive access to itself" ?
... Timing Constraints [4 Articles]
rtstofer - Dec 22 2006
I'm working on a project with the Spartan 3 Starter Board and the
Xilinx WebPack ISE version 8.2
As I look over the timing results, there are lengthy delays in the
paths conta... BRAM speed [was: Multi-context processor]
Tommy Thorn - Dec 4 2006
I just started playing with Xilinx Spartan 3E (speed grade -4) and I was appalled to find that even with extreme care can I only run the BRAMs at 170 MHz. Anything realistic and th... osx

Are there any FPGA PCI boards that support tools that work on OSX?
... FW: Verilog simulator [2 Articles]
J O - Nov 26 2006
Hello
I want to continue exploration of cpu archtectures in my past time and
wondered if anyone knew of a low cost verilog simulator that i could
purchase for home use ?
... Oddball bit widths
Rob Finch - Nov 22 2006
I think I found a relatively painless way to handle oddball bit
widths, like 10 bit bytes, 20 bit instruction words, etc. when using
standard memory parts.
I struggled for a... Looking For ALU Design
rtstofer - Nov 18 2006
I am looking for a 16 bit 2's complement ALU with
add,subtract,multiply and divide as well as the usual shift and
logical operations. This can be in multiple units like the 'yac... OpenTech 1.6.1
Jamil Khatib - Nov 18 2006
Hi,
If you already know OpenTech then you have to know that the new release
1.6.1 is available now.
OpenTech is the first world wide package of free open source hardware
design... Polled interrupts - Barrel Processor [2 Articles]
Rob Finch - Nov 17 2006
A barrel processor seems like a natural when the PLD has the ability
to support multi-contexts. All of those "extra" registers are already
just sitting there idle.
It's very...
