-This is preliminary design document on the organization of the host
-component of the USRP inband signaling implementation over USB.
-Assumptions: we'll have a single usrp_usb_daemon, implemented as an
-mblock, that will provide the high-level message based interface to
-the USRP. The daemon will handle all resource allocation, muxing and
-demuxing for the control and status messages from multiple clients.
-
-The underlying cross-process IPC mechanism is not yet specified.
-All communication will be via messages.
-
-The external interface to the usrp_usb_daemon will consist of two sets
-of replicated ports, one set for the transmit, and one set for
-receive.
-
-
-// ------------------------------------------------------------------------
-
-// Protocol class usrp_usb_common
-// Defined from client's point-of-view
-//
-// This protocol class is shared by the usrp_usb_tx and usrp_usb_rx
-// protocol classes
-

-
-cmd_allocate_channel(invocation_handle, channel, capacity_reservation)
-
-invocation_handle
-Type Handle

- The identifier will be returned with the response, to provide
- the client with a mechanism to match asynchronous responses with
- commands that generated them.
-
-channel
-Type integer
-Use Specifies the Tx channel to allocate
-
-capacity_reservation
-Type float, units are bytes/s
-Use Specifies the number of bytes/s of USB capacity to reserve for
- this channel.
-
-
-// incoming:
-
-response_allocate_channel(invocation_handle, status)
-
-Type Handle
-Use The identifier provided by the client in the prompting invocation.
- The identifier is returned with the response, so that the

- commands that generated them. The value of the invocation_handle
- is opaque to the server, and is not required by the server to be unique.
-
-Type Status

- The identifier will be returned with the response, to provide
- the client with a mechanism to match asynchronous responses with
- commands that generated them.
-
-channel
-Type integer
-Use Specifies the channel that the frame of samples shall be transmitted on.
-
-samples
-Type homogenous vector of unsigned char
-Use These samples must already be in the appropriate format for parsing
- by the USRP FPGA. The required format depends on the
- configuration associated with this channel. No conversion of
- the samples takes place in this method. Samples will be split
- into multiple USB data packets as required for transport
- across the USB.
-
-timestamp
-Type 32-bit integer
-Use Specifies the time at which the first sample in samples
- shall be sent to the D/A converter. The format and
- interpretation of time is as specified in
- inband-signaling-usb.

-Preconditions:
- a) The specified channel is allocated to this client
-
-Postconditions:
- a) If successful, the samples of the frame have been queued for
- transmission to the USRP.

- The identifier will be returned with the response, to provide
- the client with a mechanism to match asynchronous responses with
- commands that generated them.
-
-channel
-Type integer
-Use Specifies the channel that the samples shall be received from.
-
-The client may issue multiple cmd_recv_raw_samples commands to ensure
-an uninterrupted flow of samples. The appropriate number of
-outstanding cmds to issue is TBD, but is at least 2.
-
-[Discussion: I'm not sure if this is really the interface we want.
-We may want to provide an enable/disable method, and then just begin
-streaming samples. Or, we may wan to implement packet boundary
-detection in the FPGA, and then return a frame's worth of samples
-(potentially in multiple pieces).
-
-It may be that we need to different modes, one for packet based
-reception and one for continuous streaming.]

- client has a mechanism to match asynchronous responses with
- commands that generated them. The value of the invocation_handle
- is opaque to the server, and is not required by the server to be unique.
-
-samples
-Type homogenous vector of unsigned char
-Use Samples as returned by the USRP FPGA. The format of the
- returned samples depends on the configuration associated with
- this channel. No conversion or unpacking of samples takes place in
- this method.
-
-timestamp
-Type 32-bit integer
-Use Specifies the time at which the first sample in samples
- was received from the A/D converter. The format and
- interpretation of time is as specified in
- inband-signaling-usb.
-
-properties
-Type Map
-Use Returns additional (key, value) pairs associated with the
- reception of these samples. In particular, the map may contain
- the Received Strength Signal Indication (RSSI) reported by the
- front end at the time the first sample was received from the A/D.

-USRP Darwin Fast USB Changes
-Version 0.2 of 2006-04-27
-Michael Dickens <mdickens @at@ nd .dot. edu>
-
-The files included in this archive are:
-
-circular_buffer.h
-circular_linked_list.h
-darwin_libusb.h
-fusb_darwin.cc
-fusb_darwin.h
-mld_threads.h
-
-These files allow GNURadio code for Darwin / MaxOS X to talk to the
-USRP via USB 2.0 at rates up to around 30 Mega-Bytes/sec (MBps), up
-from 4-8 MBps without the changes.
-
-I implemented the buffering myself; there are probably GR buffers
-available which would do the work but as this is "beta" software it's
-a good place to start. Speed improvements are made by porting
-LIBUSB's non-true async bulk read and write functions into USRP's
-"fusb", and upgrading them to handle -true- async transfers.
-Unfortunately, the easiest way to do this is to spawn a thread or 2 to
-handle the "async" part of the transfers. This implementation uses
-Darwin's pthreads to do the work for mutexes, conditions, and threads.
-Previous implementations (0.1 and before) used "omni_threads" as
-provided by gnuradio-core, which caused issues with compiling and
-execution ... I'm glad that this is no longer the case.
-
-As far as I have tested, there is no way to improve the throughput to
-32+ MBps without moving into Darwin's "port"s ... a kernel-level data
-transport method with a user/application layer for USB-specific
-functions. Unfortunately, Apple's documentation for these "port"s is
-minimal; I have learned more from reading the Darwin source code
-< http://darwinsource.opendarwin.org/ > than by reading Apple's
-documents! This would also require -not- using LIBUSB, of which the
-removal from the rest of the USRP code would be potentially tedious.
-
-If you run into issues either compiling or testing the USRP on
-OSX, please send me a note.
-
-(1) Go through the bootstrap, configure, compile, and install as
-usual (e.g. see < http://www.nd.edu/~mdickens/GNURadio/ > for my
-usual).
-
-(2) from .../usrp/host/apps : run the scripts
-++++++++++++++++
-./test_usrp_standard_tx
-./test_usrp_standard_rx
-++++++++++++++++
-
-For -all- systems I've tested on thus far, both of these return
-exactly 41 overruns / underruns, and -most- systems start out with a
-stalled pipe. This stall comes in a usb_control funciton call to
-LIBUSB; one would have to change the LIBUSB code to handle this issue.
-
-(3) from gr-build/gnuradio-examples/python/usrp :
-++++++++++++++++
-./benchmark_usb.py
-++++++++++++++++
-
-(4) If you get to here, the try doing the FM receiver (gui or not).
-If that sounds correct, then the USB is working. Yay!

+USRP Darwin Fast USB Changes
+Version 0.2 of 2006-04-27
+Michael Dickens <mdickens @at@ nd .dot. edu>
+
+The files included in this archive are:
+
+circular_buffer.h
+circular_linked_list.h
+darwin_libusb.h
+fusb_darwin.cc
+fusb_darwin.h
+mld_threads.h
+
+These files allow GNURadio code for Darwin / MaxOS X to talk to the
+USRP via USB 2.0 at rates up to around 30 Mega-Bytes/sec (MBps), up
+from 4-8 MBps without the changes.
+
+I implemented the buffering myself; there are probably GR buffers
+available which would do the work but as this is "beta" software it's
+a good place to start. Speed improvements are made by porting
+LIBUSB's non-true async bulk read and write functions into USRP's
+"fusb", and upgrading them to handle -true- async transfers.
+Unfortunately, the easiest way to do this is to spawn a thread or 2 to
+handle the "async" part of the transfers. This implementation uses
+Darwin's pthreads to do the work for mutexes, conditions, and threads.
+Previous implementations (0.1 and before) used "omni_threads" as
+provided by gnuradio-core, which caused issues with compiling and
+execution ... I'm glad that this is no longer the case.
+
+As far as I have tested, there is no way to improve the throughput to
+32+ MBps without moving into Darwin's "port"s ... a kernel-level data
+transport method with a user/application layer for USB-specific
+functions. Unfortunately, Apple's documentation for these "port"s is
+minimal; I have learned more from reading the Darwin source code
+< http://darwinsource.opendarwin.org/ > than by reading Apple's
+documents! This would also require -not- using LIBUSB, of which the
+removal from the rest of the USRP code would be potentially tedious.
+
+If you run into issues either compiling or testing the USRP on
+OSX, please send me a note.
+
+(1) Go through the bootstrap, configure, compile, and install as
+usual (e.g. see < http://www.nd.edu/~mdickens/GNURadio/ > for my
+usual).
+
+(2) from .../usrp/host/apps : run the scripts
+++++++++++++++++
+./test_usrp_standard_tx
+./test_usrp_standard_rx
+++++++++++++++++
+
+For -all- systems I've tested on thus far, both of these return
+exactly 41 overruns / underruns, and -most- systems start out with a
+stalled pipe. This stall comes in a usb_control funciton call to
+LIBUSB; one would have to change the LIBUSB code to handle this issue.
+
+(3) from gr-build/gnuradio-examples/python/usrp :
+++++++++++++++++
+./benchmark_usb.py
+++++++++++++++++
+
+(4) If you get to here, the try doing the FM receiver (gui or not).
+If that sounds correct, then the USB is working. Yay!
