Andrew Holme has done some amazing work implementing FFT on the QPU, and has
graciously given permission to disassemble it.
(I'm assuming it was done using documentation from Broadcom, so it seems the
QPU source is not open at this stage).
Some information is at:
Accelerating Fourier transforms using the GPU
http://www.raspberrypi.org/archives/5934
The ARM side is at:
https://github.com/raspberrypi/firmware/tree/master/opt/vc/src/hello_pi/hello_fft
The QPU binaries are at:
https://github.com/raspberrypi/firmware/tree/master/opt/vc/src/hello_pi/hello_fft/hex
The latest RPI firmware has two new mailbox commands 0x00030011 and 0x00030012
see:
https://github.com/raspberrypi/firmware/blob/master/opt/vc/src/hello_pi/hello_fft/mailbox.c#L222
https://github.com/raspberrypi/firmware/blob/master/opt/vc/src/hello_pi/hello_fft/mailbox.c#L202
Protos:
unsigned execute_qpu(int file_desc, unsigned num_qpus, unsigned control,
unsigned noflush, unsigned timeout)
unsigned qpu_enable(int file_desc, unsigned enable)
For execute_qpu, 'control' points at a (videocore address) table of uniform and
code pointers - one for each QPU (num_qpus in total).
The uniform address will be set for each QPU and the code launched from the
code pointer.
Recall each QPU will run independent flow of control, but each QPU is itself a
VLIW SIMD unit.
The FFT sample uses 8 QPUs, but I assume up to 12 are supported.
I've attached a preliminary disassembly of the 256 element FFT below. Its not
commented at this stage, and there is an instruction form I havent come across
before, so it is not correctly disassembled (ldi.never).
Of course the disassembly could be rubbish, the disassembler & mnemonics are
still in a state of flux...
Cheers and Happy new year.
Herman.
