ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file. • Assume a file with correct data (no garbage, characters, etc.). • you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour: o If size = 0, then print a message “Size = 0 is unacceptable” and continue by reading the next size for the next 2 matrices (if not end of file). o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

ARMask.The ARM has six operating modes: • User (unprivileged mode under which most tasks run) • FIQ (entered when a high priority (fast) interrupt is raised) • IRQ (entered when a low priority (normal) interrupt is raised) • Supervisor (entered on reset and when a Software Interrupt instruction is executed) • Abort (used to handle memory access violations) • Undef (used to handle undefined instructions) * ARM Architecture Version 4 adds a seventh mode: • System (privileged mode using the same registers as user mode)

在軟件Proteus中仿真ucos（ARM） 1.移植除了OS_CPU.h,OS_CPU_A.s,OS_CPU_C.C 三個(gè)函數(shù)外，對(duì)中斷專門用了一個(gè)函數(shù)OS_int_A.s 按其中的規(guī)則寫中斷函數(shù)即可. 2。應(yīng)用實(shí)例為\ArmUCOS\App\test1\test.mcp,在周立功2104的板子上的ram中就可直接運(yùn)行(code＋data<16K), 注意使用了.a庫文件(我習(xí)慣這么用) 3. 將所有的文件放到D:\ArmUCOS\下,這樣上面的文件能直接編譯.

FatFs06.rar FatFs is a generic file system module to implement the FAT file system to small embedded systems. The FatFs is written in compliance with ANSI C, therefore it is independent of hardware architecture. It can be incorporated into cheap microcontrollers, such as 8051, PIC, AVR, SH, Z80, H8, ARM and etc..., without any change.
