cryptoboot is set of tools for disk encryption on Unix. It is especially suited to encrypt root partition, so _everything_ (except kernel and cryptoboot inself) is encrypted.

HHARM2410: 1. 從ftp://ftp.arm.linux.org.uk上下載linux內核,由于項目原因,先后跑了2.6.11,2.6.13和2.6.15,試了一下ftp.kernel.org上下載的2.6.16,沒跑起來,打住。 2. 編輯linux-2.6.15/Makefile, ARCH ?= $(SUBARCH) CROSS_COMPILE?= 改為 ARCH ?= arm CROSS_COMPILE?= arm-unknown-linux-gnu- 我用的編譯器是4.0.1版本的,一般的3.x的應該都沒問題

The subroutines glkern.f and lokern.f use an efficient and fast algorithm for automatically adaptive nonparametric regression estimation with a kernel method. Roughly speaking, the method performs a local averaging of the observations when estimating the regression function. Analogously, one can estimate derivatives of small order of the regression function.

qemu性能直逼VMware的仿真器QEMU 的模擬速度約為實機的 25%;約為 Bochs 的 60 倍。Plex86、User-Mode-Linux、VMware 和 Virtual PC 則比 QEMU 快一點,但 Bochs 需要特定的 Kernel Patch;User-Mode-Linux 的 Guest System 必須為 Linux;VMware 和 Virtual PC 則需要在 Guest System 上安裝特定的 Driver,且它們是針對作業系統而進行模擬,並不能說是完整的模擬器。所以 QEMU 仍不失為極優秀的 x86 模擬器。

從結構上來說,實時多任務操作系統包括兩部分,一部分為操作系統內核(kernel),即實時執行程序(Real Time Executive:RTX),另一部分是輸入輸出部分(I/O)(注意開發系統不屬于操作系統的范疇);嵌入式系統對I/O的需求通常比較小(無文件系統需求),因此很多實時多任務操作系統本質上就是一個實時執行程序,如AMX(Kadak),VRTX(Microtec),iRMX(Intel)等(這里的X即:eXecutive),如果純粹從kernel的角度來考察目前流行的各種實時多任務操作系統的性能,它們的效率差別都不大。 在市面上可以得到一些RTX的源代碼(有用C實現的,有用匯編實現的,還有用PL/M語言實現的),從internet上也可以蕩一些下來(我介紹一個站點www.eg3.com,堪稱世界電子工程師資源寶庫),下面我要介紹的一個RTX版本(我命名為SRTX:short RTX),可以說是RTX中的元老級產品了,來自某研究所,九十年代初他們到美國考察,從美國某公司購得。五年以前,SRTX在國內有售,許多搞工控的研究所利用SRTX開發了一些大型或小型的產品,這里介紹的SRTX我作了一些簡化和改動.

Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.

In a preemptive priority based RTOS, priority inversion problem is among the major sources of deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.

基于ecos的redboot,該包支持多種處理器。用戶可以根據自己硬件平臺,通過ecosconfig來配置,配置界面和編譯linux kernel差不多。本包已經正對Intel IXP2400平臺做了相應配置,硬件平臺為雙CUP架構。壓縮文件中有更為詳細的說明。
