Introduction
============
This file contains the code that runs on the Cortex-M0 core of the LPC43xx.
The M0 core is used to implement all the timing-critical usage of the SGPIO
peripheral, which interfaces to the MAX5864 ADC/DAC via the CPLD.
The M0 reads or writes 32 bytes at a time from the SGPIO registers,
transferring these bytes to or from a shared USB bulk buffer. The M4 core
handles transferring data between this buffer and the USB host.
The SGPIO peripheral is set up and enabled by the M4 core. All the M0 needs to
do is handle the SGPIO exchange interrupt, which indicates that new data can
now be read from or written to the SGPIO shadow registers.
To implement the different functions of HackRF, the M0 operates in one of
five modes, configured by the M4:
IDLE: Do nothing.
WAIT: Do nothing, but increment byte counter for timing purposes.
RX: Read data from SGPIO and write it to the buffer.
TX_START: Write zeroes to SGPIO until there is data in the buffer.
TX_RUN: Read data from the buffer and write it to SGPIO.
In all modes except IDLE, the M0 advances a byte counter, which increases by
32 each time that many bytes are exchanged with the buffer (or skipped over,
in WAIT mode).
As the M4 core produces or consumes these bytes, it advances its own counter.
The difference between the two counter values therefore indicates the number
of bytes available.
If the M4 does not advance its count in time, a TX underrun or RX overrun
occurs. Collectively, these events are referred to as shortfalls, and the
handling is similar for both.
In an RX shortfall, data is discarded. In TX mode, zeroes are written to
SGPIO. When in a shortfall, the byte counter does not advance.
The M0 maintains statistics on the the number of shortfalls, and the length of
the longest shortfall.
The M0 can be configured to abort TX or RX and return to IDLE mode, if the
length of a shortfall exceeds a configured limit.
The M0 can also be configured to switch modes automatically when its byte
counter matches a threshold value. This feature can be used to implement
timed operations.
Timing
======
This code has tight timing constraints.
We have to complete a read or write from SGPIO every 163 cycles.
The CPU clock is 204MHz. We exchange 32 bytes at a time in the SGPIO
registers, which is 16 samples worth of IQ data. At the maximum sample rate of
20MHz, the SGPIO update rate is 20 / 16 = 1.25MHz. So we have 204 / 1.25 =
163.2 cycles available.
Access to the SGPIO peripheral is slow, due to the asynchronous bridge that
connects it to the AHB bus matrix. Section 20.4.1 of the LPC43xx user manual
(UM10503) specifies the access latencies as:
Read: 4 x MCLK + 4 x CLK_PERIPH_SGPIO
Write: 4 x MCLK + 2 x CLK_PERIPH_SGPIO
In our case both these clocks are at 204MHz so reads add 8 cycles and writes
add 6. These are latencies that add to the usual M0 instruction timings, so an
ldr from SGPIO takes 10 cycles, and an str to SGPIO takes 8 cycles.
These latencies are assumed to apply to all accesses to the SGPIO peripheral's
address space, which includes its interrupt control registers as well as the
shadow registers.
There are four key code paths, with the following worst-case timings:
RX, normal: 152 cycles
RX, overrun: 76 cycles
TX, normal: 140 cycles
TX, underrun: 145 cycles
Design
======
Due to the timing constraints, this code is highly optimised.
This is the only code that runs on the M0, so it does not need to follow
calling conventions, nor use features of the architecture in standard ways.
The SGPIO handling does not run as an ISR. It polls the interrupt status.
This saves the cycle costs of interrupt entry and exit, and allows all
registers to be used freely.
All possible registers, including the stack pointer and link register, can be
used to store values needed in the code, to minimise memory loads and stores.
There are no function calls. There is no stack usage. All values are in
registers and fixed memory addresses.
Structure
=========
Each mode has its own loop routine. TX_START and TX_RUN use a single TX loop.
Code shared between different modes is implemented in macros and duplicated
within each mode's own loop.
At startup, the main routine sets up registers and memory, then falls through
to the idle loop.
The idle loop waits for a mode to be set, then jumps to that mode's start
label.
Code following the start label is executed only on a transition from IDLE. It
is at this point that the buffer statistics are reset.
Each mode's start code then falls through to its loop label.
The first step in each loop is to wait for an SGPIO interrupt and clear it,
which is implemented by the await_sgpio macro.
Then, the mode setting is loaded from memory. If the M4 has reset the mode to
idle, control jumps back to the idle loop after handling any cleanup needed.
Next, any SGPIO operations are carried out. For RX and TX, this begins with
calculating the buffer margin, and branching if there is a shortfall. Then
the pointer within the buffer is updated.
SGPIO reads and writes are implemented in 16-byte chunks. The four lowest
registers, r0-r3, are used to temporarily hold the data for each chunk. Data
is stored in-order in the buffer, but out-of-order in the SGPIO shadow
registers, due to the SGPIO architecture. A combination of single and
multiple load/stores is used to reorder the data in each chunk.
After completing SGPIO operations, counters are updated and the threshold
setting is checked. If the byte count has reached the threshold, the next
mode is set and a jump is made directly to the corresponding loop label.
Code at the start label of the new mode is not executed, so stats and
counters are maintained across a sequence of TX/RX/WAIT operations.
When a shortfall occurs, a branch is taken to a separate handler routine,
which branches back to the mode's normal loop when complete.
Most of the code for shortfall handling is common to RX and TX, and is
implemented in the handle_shortfall macro. This is primarily concerned with
updating statistics, but also handles switching back to IDLE mode if a
shortfall exceeds the configured limit.
There is a rollback mechanism implemented in the shortfall handling. This is
necessary because it is common for a harmless shortfall to occur during
shutdown, which produces misleading statistics. The code detects this case
when the mode is changed to IDLE whilst a shortfall is ongoing. If this
happens, statistics are rolled back to their values at the beginning of the
shortfall.
The backup of previous values is implemented in handle_shortfall when a new
shortfall is detected, and the rollback is implemented by the
checked_rollback routine. This routine is executed by the TX and RX loops
before returning to the idle loop.

Ordering constraints
====================
The following routines are in an unusual order, to preserve the ability to
use PC-relative conditional branches between them ("b<cond> label"). The
ordering has been chosen to ensure that all routines are close enough to each
other for the limited range of these instructions (−256 bytes to +254 bytes).
The ordering of routines, and which others each needs to be able to reach, is
as follows:
Routine: Uses conditional branches to:
idle tx_loop, wait_loop
tx_zeros tx_loop
checked_rollback idle
tx_loop tx_zeros, checked_rollback, rx_loop, wait_loop
wait_loop rx_loop, tx_loop
rx_loop rx_shortfall, checked_rollback, tx_loop, wait_loop
rx_shortfall rx_loop
If any of these routines are reordered, or made longer, you may get an error
from the assembler saying that a branch is out of range.
