+// Quantized LSTM cell implementation.
+// The quantization of the input, output arrays is as follows:
+// - The input activations are quantized as uint8 on the interval
+// [-1, 127/128].
+// The rationale for that is that is the natural interval for output
+// activations (see next point) and these need to be concatenated together.
+// We could accommodate different ranges by re-scaling, but we empirically
+// found that setting the input activations range to be [-1, 127/128] in the
+// first place, removing the need for re-scaling, greatly improves accuracy.
+// - The output activations are quantized as uint8 on the interval
+// [-1, 127/128].
+// The rationale for that is that the definition of a LSTM cell makes them
+// intrinsically constrained in [-1, 1]; tweaking that to [-1, 127/128]
+// makes for simpler, more accurate fixed-point arithmetic.
+// - The output-at-previous-timestep state array is obviously quantized as
+// the output activations.
+// - The internal LSTM memory (not the output-at-previous-timestep, the other
+// internal state array) is int16-quantized and may use any power-of-two,
+// symmetric range i.e. [-2^N, 2^N * 32767/32768] for any N, which we call
+// StateIntegerBits below, see the below discussion of that template
+// parameter ("The StateIntegerBits template parameter").
+// - The output of the internal fully-connected node is int16-quantized
+// on the interval [-8, 8 * 32767/32768], the rationale for which is
+// explained just below ("Why [-8, 8] for fully-connected output?").
+//
+//
+// === The StateIntegerBits template parameter ===
+//
+// The StateIntegerBits template parameter controls the fixed-point format used
+// to represent the internal memory of the LSTM cell (not the
+// output-at-previous-timestep, the other internal state array). It's currently
+// a template parameter so that the model can control that. The most typical
+// value for StateIntegerBits is 4. Other plausible values are anywhere between
+// 3 and 5. We might eventually standardize on a single supported value, e.g. 4,
+// and drop that template parameter. The reason why it can't be a runtime
+// parameter is that this controls the fixed-point format used, i.e. we need to
+// generate actually different code based on it. In particular, we generate code
+// for a fixed-point tanh() implementation for that format, which internally
+// uses a fixed-point exp() implementation, which internally uses a
+// barrel-shifter with a number of steps that depends on StateIntegerBits.
+// Another consequence of that is that a higher value of StateIntegerBits
+// results in a more expensive implementation (more barrel shifter steps
+// needed).
+//
+//
+// === Why [-8, 8] for fully-connected output? ===
+//
+// This array is only fed to Logistic and Tanh functions, for which
+// the quantized implementation will want to use fixed-point arithmetic,
+// requiring a power-of-two representation interval. Thus, we should right
+// away quantize this array to a power-of-two interval; otherwise,
+// implementation will need to rescale that, losing any benefit that a tighter
+// representation interval might otherwise yield, while introducing some
+// numerical error and computational overhead.
+//
+// Now, Logistic and Tanh
+// are nearly constant (nearly equal to their horizontal asymptotes)
+// outside of a small bounded interval around 0:
+//
+// Logistic(4) = 1 - 1.8e-2 Tanh(4) = 1 - 6.7e-4
+// Logistic(8) = 1 - 3.4e-4 Tanh(8) = 1 - 2.3e-7
+// Logistic(16) = 1 - 1.1e-7 Tanh(16) = 1 - 2.5e-14
+//
+// From this, we see that clamping to [-4, 4] would be too inaccurate
+// (the error of 1.8e-2 on Logistic would be felt even in 8bit precision)
+// while clamping to [-16, 16] would make no difference even in float32.
+// However, for a fixed-point implementation in 16-bit integers, using 5
+// integer bits to represent the [-16, 16] range would leave only 11
+// fractional bits, giving an increment of 2^-11 = 4.9e-4 between consecutive
+// representable values. Notice that is higher than the
+// worst-case clamping error with clamping to [-8, 8]: 3.4e-4 for Logistic.
+// Using [-8, 8] thus seems like the better compromise overall, enjoying
+// an increment of 2.4e-4 between representable values and a worst-case
+// clamping error of 3.4e-4, both better than the increment of 4.9e-4 with
+// [-16, 16].
+//
+// Moreover, all other things being equal, it is nice to choose the narrower
+// representation range, as that makes the implementation of fixed-point
+// math functions a little cheaper (each integer bit requires an additional
+// barrel-shifter atep in the implementation of exp(-x)). That is further
+// reason to prefer [-8, 8] over [-16, 16]. The choice of [-16, 16] would make
+// sense for 32-bit float or 32-bit fixed-point quantization, but we are
+// aiming for 16-bit fixed-point quantization of these internal nodes here.

+// Quantized LSTM cell implementation.
+// The quantization of the input, output arrays is as follows:
+// - The input activations are quantized as uint8 on the interval
+// [-1, 127/128].
+// The rationale for that is that is the natural interval for output
+// activations (see next point) and these need to be concatenated together.
+// We could accommodate different ranges by re-scaling, but we empirically
+// found that setting the input activations range to be [-1, 127/128] in the
+// first place, removing the need for re-scaling, greatly improves accuracy.
+// - The output activations are quantized as uint8 on the interval
+// [-1, 127/128].
+// The rationale for that is that the definition of a LSTM cell makes them
+// intrinsically constrained in [-1, 1]; tweaking that to [-1, 127/128]
+// makes for simpler, more accurate fixed-point arithmetic.
+// - The output-at-previous-timestep state array is obviously quantized as
+// the output activations.
+// - The internal LSTM memory (not the output-at-previous-timestep, the other
+// internal state array) is int16-quantized and may use any power-of-two,
+// symmetric range i.e. [-2^N, 2^N * 32767/32768] for any N, which we call
+// StateIntegerBits below, see the below discussion of that template
+// parameter ("The StateIntegerBits template parameter").
+// - The output of the internal fully-connected node is int16-quantized
+// on the interval [-8, 8 * 32767/32768], the rationale for which is
+// explained just below ("Why [-8, 8] for fully-connected output?").
+//
+//
+// === The StateIntegerBits template parameter ===
+//
+// The StateIntegerBits template parameter controls the fixed-point format used
+// to represent the internal memory of the LSTM cell (not the
+// output-at-previous-timestep, the other internal state array). It's currently
+// a template parameter so that the model can control that. The most typical
+// value for StateIntegerBits is 4. Other plausible values are anywhere between
+// 3 and 5. We might eventually standardize on a single supported value, e.g. 4,
+// and drop that template parameter. The reason why it can't be a runtime
+// parameter is that this controls the fixed-point format used, i.e. we need to
+// generate actually different code based on it. In particular, we generate code
+// for a fixed-point tanh() implementation for that format, which internally
+// uses a fixed-point exp() implementation, which internally uses a
+// barrel-shifter with a number of steps that depends on StateIntegerBits.
+// Another consequence of that is that a higher value of StateIntegerBits
+// results in a more expensive implementation (more barrel shifter steps
+// needed).
+//
+//
+// === Why [-8, 8] for fully-connected output? ===
+//
+// This array is only fed to Logistic and Tanh functions, for which
+// the quantized implementation will want to use fixed-point arithmetic,
+// requiring a power-of-two representation interval. Thus, we should right
+// away quantize this array to a power-of-two interval; otherwise,
+// implementation will need to rescale that, losing any benefit that a tighter
+// representation interval might otherwise yield, while introducing some
+// numerical error and computational overhead.
+//
+// Now, Logistic and Tanh
+// are nearly constant (nearly equal to their horizontal asymptotes)
+// outside of a small bounded interval around 0:
+//
+// Logistic(4) = 1 - 1.8e-2 Tanh(4) = 1 - 6.7e-4
+// Logistic(8) = 1 - 3.4e-4 Tanh(8) = 1 - 2.3e-7
+// Logistic(16) = 1 - 1.1e-7 Tanh(16) = 1 - 2.5e-14
+//
+// From this, we see that clamping to [-4, 4] would be too inaccurate
+// (the error of 1.8e-2 on Logistic would be felt even in 8bit precision)
+// while clamping to [-16, 16] would make no difference even in float32.
+// However, for a fixed-point implementation in 16-bit integers, using 5
+// integer bits to represent the [-16, 16] range would leave only 11
+// fractional bits, giving an increment of 2^-11 = 4.9e-4 between consecutive
+// representable values. Notice that is higher than the
+// worst-case clamping error with clamping to [-8, 8]: 3.4e-4 for Logistic.
+// Using [-8, 8] thus seems like the better compromise overall, enjoying
+// an increment of 2.4e-4 between representable values and a worst-case
+// clamping error of 3.4e-4, both better than the increment of 4.9e-4 with
+// [-16, 16].
+//
+// Moreover, all other things being equal, it is nice to choose the narrower
+// representation range, as that makes the implementation of fixed-point
+// math functions a little cheaper (each integer bit requires an additional
+// barrel-shifter atep in the implementation of exp(-x)). That is further
+// reason to prefer [-8, 8] over [-16, 16]. The choice of [-16, 16] would make
+// sense for 32-bit float or 32-bit fixed-point quantization, but we are
+// aiming for 16-bit fixed-point quantization of these internal nodes here.
