By the way, we have a new toy: FN now has a "pfpu" command (command line only) that loads register settings and PFPU code, then executes the code, and dumps the register contents. This should be useful for debugging math problems. I've written a little assembler for it, in milkymist.git under tools/asm/ Example: /* * blabla */ r2 = 23.4 r3 = 18.6 r4 = 0 fadd r2, r3 -> r4 nop nop nop nop vectout r0, r0 -> r0 This PFPU code, so the user has to take care of the scheduling. The input is passed through cpp, so anything cpp understands, from comments via macro to scommand-line options, is recognized. Lower and upper case are accepted but case can't be mixed within the same name. This gets translated to: 0x41bb3333 # R2 = 23.400000 0x4194cccd # R3 = 18.600000 0x00000000 # R4 = 0.000000 00081880 # 0: FADD R2, R3 -> R4 @ 5 00000000 # 1: NOP 00000000 # 2: NOP 00000000 # 3: NOP 00000000 # 4: NOP 00000384 # 5: VECTOUT R0, R0 dest R4 There's a script called "pfpu" that runs the assembler and sends the resulting code to $M1_HOST, with telnet user $M1_USER and password $M1_PW. The FN session would look like this: Connection to m1 23 port [tcp/telnet] succeeded! Welcome to rtems-4.10.99.0(LM32/lm32/milkymist) COPYRIGHT (c) 1989-2008.

The first register for input and output is R2. There's no synchronization with anything else FN does and running "pfpu" while rendering or even compiling will result in a very sick PFPU. - Werner _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkymist@Freenode
