Inherits CpuSystemFeature.

Static Public Attributes

static final ArmCpuSystemFeature VFPVectorMode = new ArmCpuSystemFeature(32)
 VFP vector mode is supported in hardware.
 
static final ArmCpuSystemFeature FPA = new ArmCpuSystemFeature(56)
 The CPU has FPA registers (f0-f7), and the operating system preserves them during context switch.
 
static final ArmCpuSystemFeature WMMX = new ArmCpuSystemFeature(57)
 The CPU has WMMX registers (wr0-wr15), and the operating system preserves them during context switch.
 
static final ArmCpuSystemFeature S32 = new ArmCpuSystemFeature(58)
 The CPU has s0-s31 VFP registers, and the operating system preserves them during context switch.
 
static final ArmCpuSystemFeature D32 = new ArmCpuSystemFeature(59)
 The CPU has d0-d31 VFP registers, and the operating system preserves them during context switch.
 
- Static Public Attributes inherited from CpuSystemFeature
static final CpuSystemFeature CycleCounter = new CpuSystemFeature(0)
 The processor has a built-in cycle counter, and the operating system provides a way to access it.
 
static final CpuSystemFeature CycleCounter64Bit = new CpuSystemFeature(1)
 The processor has a 64-bit cycle counter, or the operating system provides an abstraction of a 64-bit cycle counter.
 
static final CpuSystemFeature AddressSpace64Bit = new CpuSystemFeature(2)
 The processor and the operating system allows to use 64-bit pointers.
 
static final CpuSystemFeature GPRegisters64Bit = new CpuSystemFeature(3)
 The processor and the operating system allows to do 64-bit arithmetical operations on general-purpose registers.
 
static final CpuSystemFeature MisalignedAccess = new CpuSystemFeature(4)
 The processor and the operating system allows misaligned memory reads and writes.
 
static final CpuSystemFeature SingleThreaded = new CpuSystemFeature(5)
 The processor or the operating system support at most one hardware thread.
