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.
AutoBoot is a generic boot loader that automatically locates, loads, and
Executes object files from multiple types of media. AutoBoot provides a simple,
fast, and functional means of loading an OS image while maintaining a small
Flash memory footprint. This binary release contains a stand-alone version of
AutoBoot for the DbAu1200 development board, designed to replace the YAMON boot
loader.
JMODEM Executes best from a batch file as an external pro-
tocol for any of the communications programs that have ex-
ternal-protocol capability. A typical communications program
is TELIX.

The P89LPC912/913/914 are single-chip microcontrollers in low-cost 14-pin packages, based on a high performance processor architecture that Executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system level functions have been incorporated into the P89LPC912/913/914 in order to reduce component count, board space, and system cost.

NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core Executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.
Nios II 軟件開發人員手冊中的緩存和緊耦合存儲器部分
Nios® II embedded processor cores can contain instruction and data caches. This
chapter discusses cache-related issues that you need to consider to guarantee that
your program Executes correctly on the Nios II processor. Fortunately, most software
based on the Nios II hardware abstraction layer (HAL) works correctly without any
special accommodations for caches. However, some software must manage the cache
directly. For code that needs direct control over the cache, the Nios II architecture
provides facilities to perform the following actions:
a Java program that reads a file containing instructions written in self-defined file (TPL in this case), and Executes those instructions. This program should take the name of the TPL file as a command line parameter, and write its output to the console.
onBlur event handler
A blur event occurs when a text or textArea field on a form loses focus. The onBlur event handler Executes JavaScript code when a blur event occurs.
