his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable CLOCK from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any CLOCK signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default CLOCK output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

* DEFINITION * This a set of math functions that deal with time. The functions accept * 4-digit time values and 4-digit time of day values. Time values are * interpreted as hours-minutes and are valid if all digits are numeric and * 9 or less, except the second-to-last digit must be 5 or less. Time of day * values are valid if they conform to normally accepted CLOCK values of * 1:00 to 12:59 for a 12-hour CLOCK or 00:00 to 23:59 for a 24-hour CLOCK.

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 “latency-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.

SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating with a 100MHz Bus CLOCK. The rating is based on Dhrystone 2.1. It shows the rate when I+D Caches are disabled or enabled, with or without MMU and I Cache is disable or enabled, with or without MMU.

The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and CLOCK rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

TLC549是一種采用8位逐次逼近式工作的A/D轉換器。內部包含系統時鐘、采樣和保持、8位A/D轉換器、數據寄存器以及控制邏輯電路。TLC549每25uS重復一次“輸入—轉換—輸出”。器件有兩個控制輸入：I/O CLOCK和片選（CS）。 內部系統時鐘和I/O CLOCK可獨立使用。應用電路的設計只需利用I/O時鐘啟動轉換或讀出轉換結果。當CS為高電平時，DATA OUT處于高阻態且I/O時鐘被禁止。
