What is Octal SPI?
Octal SPI is the serial synchronous communication protocol developed by Macronix(CMOS MXSMIO®(SERIAL MULTI I/O) Flash memory). Octal SPI (Serial Peripheral Interface) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
What is SPI flash used for?
SPI flash memory, also known as flash memory, has become widely used in the embedded industry and is commonly used for storage and data transfer in portable devices. Common devices include phones, tablets, and media players, as well as industrial devices such as security systems and medical products.
What is hyper flash memory?
HyperBus Memory is a portfolio of high-speed, low-pin-count NOR Flash and Expansion RAM memory products that uses our HyperBus interface technology. They deliver high read bandwidth at 333MB/s, over four times faster than Quad SPI NOR flash with one-third the number of pins of parallel NOR flash.
What does dual / Quad i / o mean in SPI?
A dual I/O (two-bit data bus) interface enables transfer rates to double compared to the standard serial Flash memory devices. A quad I/O (four-bit data bus) interface improves throughput four times. \\$\\begingroup\\$ That’s not an SPI device — SPI doesn’t use bidirectional pins.
Which is better dual or Quad I / O interface?
A dual I/O (two-bit data bus) interface enables transfer rates to double compared to the standard serial Flash memory devices. A quad I/O (four-bit data bus) interface improves throughput four times. It means that you have more serial lines that share the same control signals, or put differently, a serial port with more than one data line.
Are there flash chips that support dual and quad SPI?
Flash chips that support Quad SPI generally support Dual SPI. Single, Dual, and Quad SPI are also pin-compatible. More information about the flash chip can be found on its respective datasheet. Total Phase offers a variety of tools for different SPI configurations.
Which is better quad channel or quad channel memory?
So, the 16GB quad vs 16GB dual results shouldn’t mean anything other than that running four sticks of 4GB of RAM in dual channel configuration didn’t really offer any performance boost over running two sticks of 8GB of RAM in dual channel configuration and vice versa.
