"On-Chip FPGA Advanced Learning Tour" ddr2+ Gigabit Ethernet circuit design based on Altera FPGA

DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit

FPGA learning notes Altera FPGA using JIC file to configure the Cure tutorial (GO)

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr

Implementation of OBJECTIVE-C SHA224/SHA256/SHA384/SHA512 encryption algorithm for iOS development

Previously implemented in the blog SHA1 Security has not met the needs of users, today the implementation of the sha224/sha256/sha384/sha512 attached. The SHA that Secure Hash algorithm (safe hashing algorithm) has many kinds of different bit number realization, common has sha224/sha256/sha384/sha512 and so on SHA224: -(nsstring*) sha224{ const char *CSTR = [self cstringusingencoding:nsutf8stringenco

How to Use SHA256 to verify downloaded files

How to Use SHA256 to verify downloaded files When you download an ISO image, especially from many unknown seeds on the BitTorrent network, we recommend that you verify the integrity of the downloaded image. For the Ubuntu release, Canonical provides several verification files (such as MD5SUM, SHA1SUMS, and SHA256SUMS) for verification ). In this example, we use SHA256SUMS. First, download the following two files. $ Wget

My FPGA Learning History (--FPGA) basic knowledge and Quartus installation

The advanced embedded market is divided into the following three categories: ARM, DSP and FPGA. ARM is the industry leader, currently almost all Android smartphones use ARM authorized CPU architecture, while DSP (digital signal processor) has been widely used in the early years of the telephone, DVD, communication base Station and other fields. The difference between DSP and arm is that arm is a universal CPU,DSP and a dedicated CPU.

Microsoft digital signature code signing using the SHA256 certificate

Microsoft was the first to announce the SHA-1 deprecation program, and after 2016 years windows and IE will no longer trust the SHA-1 certificate. Just as our company's digital signature also expires, simply re-applied for SHA256 and SHA1 new digital certificate, used to sign the product.Looking at Signcode's document discovery,signcode 's command line-A is the signature algorithm used to specify a digital signature, supports only SHA1 and MD5, and do
