[处理器开发] nand_read
本源码是基于S3C—6430的ARM11嵌入式开发板的NAND FLASH程序的编写。NAND写回速度快、芯片面积小，特别是大容量使其优势明显。页是NAND中的基本存贮单元，一页一般为512 B(也有2 kB每页的large page NAND FLASH)，多个页面组成块。不同存储器内的块内页面数不尽相同，通常以16页或32页比较常见。块容量计算公式比较简单，就是页面容量与块内页面数的乘积。根据FLASH Memory容量大小，不同存储器中的块、页大小可能不同，块内页面数也不同。例如：8 MB存储器，页大小常为512 B、块大小为8 kB，块内页面数为16。而2 MB的存储器的页大小为256 B、块大小为4 kB，块内页面数也是16。NAND存储器由多个块串行排列组成。实际上，NAND型的FLASHMemory可认为是顺序读取的设备，他仅用8 b的I/O端口就可以存取按页为单位的数据。NAND在读和擦写文件、特别是连续的大文件时，速度相当快。
NAND write-back speed, small chip area, especially the large capacity make it obvious advantages. Page in the NAND storage unit, a general 512 B, (also have 2 kB per page large page NAND FLASH), multiple page composition. Number of pages within the memory block is different, usually more common 16 or 32. Block capacity formula is relatively simple, is the product of the page capacity and number of pages in the block. FLASH Memory size memory block, the page size may be different, the number of pages in the block. For example: 8 MB of memory, the page size is often 512 B, the block size of 8 kB, the number of pages in the block 16. The page size of 2 MB of memory, 256 B, the block size is 4 kB block, number of pages is 16. NAND memory by more than one block of the serial arrangement. In fact, NAND FLASHMemory can be considered to be the order of read devices, he took only 8-b I/O ports can access the data by page. NAND read and erase files, especially consecutive large files very fast. (2012-02-13, Unix_Linux, 3KB, 下载13次)
[处理器开发] CPU-tool-chain-design
摘要：EDA技术的成熟和进步，缩短了微处理器硬件设计和综合的周期。同时，开发工具链设计的自动化，已成了高效率、高质量嵌入式微处理器设计的重要内容。本文提出了采用体系结构描述语言(ADL)实现微处理器开发工具链自动设计的有效方法。针对ADL描述流水线的局限性，进行了扩展改进，因而使改进后的ADL能用来直接描述流水线。新方法在CK幸CORE开发工具链设计中的应用表明，比用GNU工具链功效有了显著提高。
Abstract: EDA technologies mature and progress, reducing microprocessor hardware design and integrated cycle. Meanwhile, the development tool chain design automation, has become a high efficiency, high quality an important part of the embedded microprocessor design. In this paper, architecture description language used (ADL) to achieve automatic design of microprocessor development tool chain and effective method. ADL describes the pipeline for the limitations is extended to improve, thereby improved ADL can be used to directly describe the pipeline. Fortunately, the new method in CK CORE development tool chain design that use the GNU tool chain effects than have been significantly improved. (2011-04-15, Unix_Linux, 383KB, 下载3次)

This simulator is a cycle-accurate system-level energy and timing simulator. Developed by Embedded Low-Power Laboratory, Seoul National University. The simulator’s underlying kernel is OSCI SystemC 2.2.0. All of the hardware modules satisfies the OSCI standards.
The simulator is composed of a CPU, cache, and memory components including DDR SDRAM, MLC NOR Flash, MLC NAND Flash, SRAM. Each memory components have it’s own memory model, which enables cycle-accurate power consumption estimation of the devices. Master and slave SystemC IPs are connected through AMBA AHB CLI (Cycle-Level Interface). You will get energy trace files for each memory devices. You will get cycle-accurate performance evaluation results CPU cycle counts information, and cache hit/miss ratio on console. Also, you can get trace files for memory devices.
The simulator exhibits performance over 500 K instructions/sec, which is fairly high for a cycle-accurate system-level simulator.
