tServer task executes functions at low priority (254). serverSend
funtion is used to send a request to the tServer to execute a
function at the tServer s priority.
First tServer task executes the i() system call to print the summary
of tShell task. Next an address exception is caused in tServer
task by trying to execute a funtion at non-aligned word boundry.
As a result SIGBUS signal is raised automatically. Signals
(setjmp() and longjmp()) are used to allow the tServer task to
recover gracefully from an address error exception. For more
information about signals, please refer to sigLib manual pages.

Pipeline synchronization is a simple, low-cost, highbandwidth,highreliability solution to interfaces between synchronous and asynchronous systems, or between
synchronous systems operating from different clocks.
This paper presents several low-latency mixed-timing
FIFO (first-in–first-out) interfaces designs that interface systems
on a chip working at different speeds. The connected systems
can be either synchronous or asynchronous. The designs are then
adapted to work between systems with very long interconnect
delays, by migrating a single-clock solution by Carloni et al.
(1999, 2000, and 2001) (for “l(fā)atency-insensitive” protocols) to
mixed-timing domains. The new designs can be made arbitrarily
robust with regard to metastability and interface operating speeds.
Initial simulations for both latency and throughput are promising.
