Q.no.1 What is the maximum operating frequency of picoblaze microcontrooler ?
Q.no.2 What maximum baud rate is supported by the UART provided with xilinx FPGAs ?
Q.no.3 i have an 200ms spaced, incoming data packet (68 bytes) stream at 115.2 kbps speed ! would the picoblaze along with the provided UART( xilinx) be able to store that packet stream and convert the packet into other packet form ? at real time ?
( i m willing to use VHDL version of the Picoblaze available from xilinx optimized for spartan II )
Q.no.4 Is any C - COmpiler available for Picoblaze microcontroller ?
1) Depends on the FPGA u use.
44 MIPS Spartan 3 @ 88Mhz
100 MIPS Virtex II PRO @ 200MHz
Picoplaze can do one instruction in zwo clockcycles
2)>10 MBit when don't uses RS232
I have running my connection from PC to FPGA with 115.2 kbps
3) Maybe, what conversion do u want to do?
4) A know only the assembler
All information u requestet can be found in the Picoplaze and UART documentation.
