<h4 class="subsection">6.59.13 MIPS DSP Built-in Functions</h4>
|
||
|
|
|
||
|
|
<p>The MIPS DSP Application-Specific Extension (ASE) includes new
|
||
|
|
instructions that are designed to improve the performance of DSP and
|
||
|
|
media applications. It provides instructions that operate on packed
|
||
|
|
8-bit/16-bit integer data, Q7, Q15 and Q31 fractional data.
|
||
|
|
</p>
|
||
|
|
<p>GCC supports MIPS DSP operations using both the generic
|
||
|
|
vector extensions (see <a href="Vector-Extensions.html#Vector-Extensions">Vector Extensions</a>) and a collection of
|
||
|
|
MIPS-specific built-in functions. Both kinds of support are
|
||
|
|
enabled by the <samp>-mdsp</samp> command-line option.
|
||
|
|
</p>
|
||
|
|
<p>Revision 2 of the ASE was introduced in the second half of 2006.
|
||
|
|
This revision adds extra instructions to the original ASE, but is
|
||
|
|
otherwise backwards-compatible with it. You can select revision 2
|
||
|
|
using the command-line option <samp>-mdspr2</samp>; this option implies
|
||
|
|
<samp>-mdsp</samp>.
|
||
|
|
</p>
|
||
|
|
<p>The SCOUNT and POS bits of the DSP control register are global. The
|
||
|
|
WRDSP, EXTPDP, EXTPDPV and MTHLIP instructions modify the SCOUNT and
|
||
|
|
POS bits. During optimization, the compiler does not delete these
|
||
|
|
instructions and it does not delete calls to functions containing
|
||
|
|
these instructions.
|
||
|
|
</p>
|
||
|
|
<p>At present, GCC only provides support for operations on 32-bit
|
||
|
|
vectors. The vector type associated with 8-bit integer data is
|
||
|
|
usually called <code>v4i8</code>, the vector type associated with Q7
|
||
|
|
is usually called <code>v4q7</code>, the vector type associated with 16-bit
|
||
|
|
integer data is usually called <code>v2i16</code>, and the vector type
|
||
|
|
associated with Q15 is usually called <code>v2q15</code>. They can be
|
||
|
|
defined in C as follows:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">typedef signed char v4i8 __attribute__ ((vector_size(4)));
|
||
|
|
typedef signed char v4q7 __attribute__ ((vector_size(4)));
|
||
|
|
typedef short v2i16 __attribute__ ((vector_size(4)));
|
||
|
|
typedef short v2q15 __attribute__ ((vector_size(4)));
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p><code>v4i8</code>, <code>v4q7</code>, <code>v2i16</code> and <code>v2q15</code> values are
|
||
|
|
initialized in the same way as aggregates. For example:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">v4i8 a = {1, 2, 3, 4};
|
||
|
|
v4i8 b;
|
||
|
|
b = (v4i8) {5, 6, 7, 8};
|
||
|
|
|
||
|
|
v2q15 c = {0x0fcb, 0x3a75};
|
||
|
|
v2q15 d;
|
||
|
|
d = (v2q15) {0.1234 * 0x1.0p15, 0.4567 * 0x1.0p15};
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p><em>Note:</em> The CPU’s endianness determines the order in which values
|
||
|
|
are packed. On little-endian targets, the first value is the least
|
||
|
|
significant and the last value is the most significant. The opposite
|
||
|
|
order applies to big-endian targets. For example, the code above
|
||
|
|
sets the lowest byte of <code>a</code> to <code>1</code> on little-endian targets
|
||
|
|
and <code>4</code> on big-endian targets.
|
||
|
|
</p>
|
||
|
|
<p><em>Note:</em> Q7, Q15 and Q31 values must be initialized with their integer
|
||
|
|
representation. As shown in this example, the integer representation
|
||
|
|
of a Q7 value can be obtained by multiplying the fractional value by
|
||
|
|
<code>0x1.0p7</code>. The equivalent for Q15 values is to multiply by
|
||
|
|
<code>0x1.0p15</code>. The equivalent for Q31 values is to multiply by
|
||
|
|
<code>0x1.0p31</code>.
|
||
|
|
</p>
|
||
|
|
<p>The table below lists the <code>v4i8</code> and <code>v2q15</code> operations for which
|
||
|
|
hardware support exists. <code>a</code> and <code>b</code> are <code>v4i8</code> values,
|

|
|
and <code>c</code> and <code>d</code> are <code>v2q15</code> values.

<p>It is easier to describe the DSP built-in functions if we first define
|
||
|
|
the following types:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">typedef int q31;
|
||
|
|
typedef int i32;
|
||
|
|
typedef unsigned int ui32;
|
||
|
|
typedef long long a64;
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p><code>q31</code> and <code>i32</code> are actually the same as <code>int</code>, but we
|
||
|
|
use <code>q31</code> to indicate a Q31 fractional value and <code>i32</code> to
|
||
|
|
indicate a 32-bit integer value. Similarly, <code>a64</code> is the same as
|
||
|
|
<code>long long</code>, but we use <code>a64</code> to indicate values that are
|
||
|
|
placed in one of the four DSP accumulators (<code>$ac0</code>,
|
||
|
|
<code>$ac1</code>, <code>$ac2</code> or <code>$ac3</code>).
|
||
|
|
</p>
|
||
|
|
<p>Also, some built-in functions prefer or require immediate numbers as
|
||
|
|
parameters, because the corresponding DSP instructions accept both immediate
|
||
|
|
numbers and register operands, or accept immediate numbers only. The
|
||
|
|
immediate parameters are listed as follows.
|
||
|
|
