The API implementation for the PSL is given in the following code:
macro proc PSLFlashRun (ClockRate)
{
FlashInit (&FlashPtr, FlashAddrPins, FlashDataPins,
FlashChipEnablePins, FlashOutputEnablePin,
FlashWriteEnablePin, FlashStatusPin,
FlashByteEnablePin, FlashEraseEnablePin);
FlashRun (FlashPtr, ClockRate);
}
macro proc PSLFlashReadWord (Address, DataPtr)
{
FlashReadWord (FlashPtr, Address, DataPtr);
}
macro proc PSLFlashWriteWord (Address, Data)
{
FlashWriteWord (FlashPtr, Address, Data);
}
macro proc PSLFlashEraseBlock (BlockNumber)
{
FlashEraseBlock (FlashPtr, BlockNumber);
}
4 Tutorial: Handel-C and PSL basics
The Handel-C and PSL basics tutorial demonstrates:
• Basic use of the common Handel-C operators which are not present in C or C++.
• How to create a device driver for a Platform Support Library.
• How to make the driver portable by using the Platform Abstraction Layer.
The examples can be used with any FPGA-based board, but are shown configured for the Celoxica
RC200.
New users are recommended to work through the following topics in order:
•
Handel-C language basics (see page 45)
•
Creating a device driver (see page 53)
