qat.purr.backends.qblox.codegen module

class AbstractContext(alloc_mgr=None)

Bases: ABC

clear()

create_package(target)

delay(inst)

device_update(du_inst)

property duration

property durations

id()

is_empty(): Masks away yet-to-be-supported second-state, cancellation, and cross cancellation targets This is temporary and criteria will change with more features coming in

ledger(duration, pulse=None)

property phase

reset_phase()

shift_frequency(inst, target)

shift_phase(inst)

static synchronize(inst, contexts): Favours static time padding whenever possible, or else uses SYNC. TODO - Default to SYNC when Qblox supports finer grained SYNC groups

wait_imm(duration)

Waits for duration nanoseconds expressed as an immediate.

duration must be positive

wait_reg(duration)

A mere wait RX in general has undefined runtime behaviour.

This is a useful helper to dynamically wait for a duration nanoseconds expressed as a register. iter_reg is a short-lived register only used as an interator. Customer is responsible for (de)allocation.

waveform(waveform, target)

class AllocationManager(_reg_pool=<factory>, _lbl_counters=<factory>, registers=<factory>, labels=<factory>)

Bases: object

label_gen(name)

labels: Dict[str, str]

reg_alloc(name)

Return type:: str

reg_borrow(name): Short-lived register allocation

reg_free(register)

Return type:: None

registers: Dict[str, str]

class NewQbloxContext(alloc_mgr, scoping_result, rw_result, iter_bounds)

Bases: AbstractContext

static enter_repeat(inst, contexts)

static enter_sweep(inst, contexts)

static exit_repeat(inst, contexts)

static exit_sweep(inst, contexts)

measure_acquire(measure, acquire, target)

class NewQbloxEmitter

Bases: InvokerMixin

build_pass_pipeline(*args, **kwargs)

emit_packages(ir, res_mgr, met_mgr, ignore_empty=True)

Return type:: List[QbloxPackage]

class PreCodegenPass

Bases: AnalysisPass

run(ir, res_mgr, *args, **kwargs): Precedes assembly codegen. Performs a naive register allocation through a manager object. Computes useful information in the form of attributes.
