An essential component of a noise-free audio device isa clean power supply, but few switching regulators canoperate at high efficiency while keeping the switchingfrequency out of the audio band. The LTC®3620 fills thisvoid. It is a high efficiency 15mA buck regulator with aprogrammable minimum switching frequency, making itpossible to virtually eliminate audible switching noise. Theinternal synchronous switches and low quiescent currentof this buck regulator provide the ability to maintain highefficiency, while its small Footprint makes it ideal for tiny,low power audio applications.
The LTM8020, LTM8021, LTM8022 and LTM8023 μModule®regulators are complete easy-to-use encapsulated stepdownDC/DC regulators intended to take the pain and aggravationout of implementing a switching power supplyonto a system board. With a μModule regulator, you onlyneed an input cap, output cap and one or two resistorsto complete the design. As one might imagine, this highlevel of integration greatly simplifi es the task of printedcircuit board design, reducing the effort to four categories:component Footprint generation, component placement,routing the nets, and thermal vias.
The Tri-Mode Ethernet MAC (TEMAC) UltraController-II module is a minimal Footprint,embedded network processing engine based on the PowerPC™ 405 (PPC405) processor coreand the TEMAC core embedded within a Virtex™-4 FX Platform FPGA. The TEMACUltraController-II module connects to an external PHY through Gigabit Media IndependentInterface (GMII) and Management Data Input/Output (MDIO) interfaces and supports tri-mode(10/100/1000 Mb/s) Ethernet. Software running from the processor cache reads and writesthrough an On-Chip Memory (OCM) interface to two FIFOs that act as buffers between thedifferent clock domains of the PPC405 OCM and the TEMAC.
JILRuntime A general purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. Objects and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for embedded systems where a small memory Footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, general purpose programming environment.
Client/Server版本 DBISAM compiles directly into your application with no external libraries required. Runtime package support is also provided if so desired. It has a very small Footprint and does not require any forms support in Delphi 6, C++Builder 6, and Kylix 2 and higher, which helps keep the size of non-UI applications like services or web applications to a minimum.
This a naive implementation of BOOTP/TFTPBOOT, the protocols
to use to bootstrap a computer through a TCP/IP network.
The goal was to design a small Footprint implementation
to allow the code to be integrated into a monitor program
stored in a ROM/FLASH, the Footprint is about 7 KBytes
for the test program.
This code has not been yet tested in many environment.
It should be seen at your starting point to integrate
the network boot function to your board.
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.
Very very small GUI. Usefull for small system,
without OS or small OS. Event driven, support user message to GUI.
included simle widgets: nested menu, window, dialog, inputline, scroll list.
Footprint for 16 bit CPU - aprox. 60kB.
Languadge - C
