Choice of different Interfaces Used in Co-Processor mode of CY7C67300
Based on throughput, which interface is the popular choice?
The throughputs for SPI interface that can be used for coprocessor mode in CY7C67300 is up to 12 Mbit/s.
HPI is a popular choice because of the speed at which it can move data. The throughput with HPI is up to 16 MB/s. Both of the serial interfaces, SPI and HSS, are much slower due to the serial nature of the interface and the additional overhead required for a serial interface. However, depending upon your application, the SPI serial interface is still adequate and is desirable when connecting to a system processor that has the same serial interface.
