A typical process includes process explained in Figure 3. This process does not take the full advantage of the SPI throughput and end up being very slow. So a total of 43 clock cycles are required to receive 16 bytes of data, which results in overall throughput of 20 MBps. Execute in place feature removes the controller latency and converts the controller into a memory mapped interface. This lets user execute the code on NOR flash memories in place and hence called Execute in Place mode.
In similar scenario as explained above the throughput calculations are updated as below:. So it takes a total of 23 clock cycles to transmit 16 bytes of data resulting in overall throughput of 55 MBps. Ever since the introduction of Execute in place memories, SPI has become very popular for low power solutions. There are many innovations done by memory devices to reduce boot time of device like removal of address phase from the XIP transfers.
These improvements have decreased the memory access time significantly. Still the overall throughput utilization is less for the device. Still there are some techniques that can be utilized to improve the throughput further, following sections discusses such techniques.
Another way in which user can improve the performance further is by increasing the block size of device.
For example, if we want to fetch 1 KB of data from memory there are two ways in which it can be done. In this method the data is pipelined utilizing the complete bandwidth of the device. Flash configuration memories are usually serial Flash chips. Yet, the main difference between serial and parallel NOR flash is the way the memory is accessed. Sign up to join this community.
