abstract= "This paper reports on the development of an interconnection
scheme for field-programmable gate arrays (FPGAs). These
FPGAs may be programmed in the Occam parallel programming
language. Now, not only may the inter-process communication
channels provided by Occam be used on-chip, but they may
also be extended to a host processor using the ubiquitous
Universal Serial Bus (USB). Bidirectional channels of BYTEs
are carried along this bus to a host processor (running
Linux) where they are presented to application code using a
device driver that provides similar capabilities to the
standard B004 card link driver. A unidirectional end-to-end
throughput between Linux processes and FPGA processes,
across USB, has been measured as high as 1025 kbytes/sec,
although this rate is only achieved in favourable
circumstances. Similarly, 410 kbytes/sec may be transferred
in both directions simultaneously. Unidirectional
transmission rates of more than 600 kbytes/sec, and
bidirectional rates of 175-300 kbytes/sec in each direction
may be achieved in a wide range of circumstances. The paper
presents a range of performance figures, explaining which
are limited by the underlying characteristics of the USB bus
and which are caused by the current implementation. By
implementing a transputer OS-Link in the FPGA, it is
possible for a USB- enabled computer to communicate with a
network of transputers, providing a convenient - and
potentially faster - alternative to previous methods."
