Accessing Memory in EPCS Devices
You can access the unused memory locations of the EPCS device to store or retrieve
data through the Nios processor and SOPC Builder. SOPC Builder is an Altera tool for
creating bus-based (especially microprocessor-based) systems in Altera devices.
SOPC Builder assembles library components such as processors and memories into
custom microprocessor systems.
SOPC Builder includes the EPCS device controller core, which is an interface core
designed specifically to work with the EPCS device. With this core, you can create a
system with a Nios embedded processor that allows software access to any memory
location within the EPCS device.
Active Serial FPGA Configuration
The following Altera FPGAs support the AS configuration scheme with EPCS devices:
Arria series
Cyclone series
All device families in the Stratix series except the Stratix device family
There are four signals on the EPCS device that interface directly with the FPGA’s
control signals. The EPCS device signals are DATA, DCLK, ASDI, and nCS interface with
the DATA0, DCLK, ASDO, and nCSO control signals on the FPGA, respectively.
