Processor Components
Table 4-34 Core configuration parameters (continued)
Parameter Description Default
cpu[n].implements_vfp Support VFP in this CPU true
cpu[n].fpsID Value for Floating-point System ID Register 0x41033091
cpu[n].implements_vfpd16-d31
cpu[n].implements_vfp_short_vectors
If VFP is implemented, support 32 double-precision
registers. Otherwise 16 are supported. If NEON is
implemented, 32 registers are always supported and this
parameter is ignored.
Enable support for vfp short vector operations, as indicated
by MVFR0[27:24]
true
true
cpu[n].implements_fused_mac Implement the vfp fused multiply accumulate operations false
cpu[n].implements_sdiv_udiv Implement the integer divide operations false
cpu[n].vfp-enable_at_reset
cpu[n].use_IR
VFP registers are enabled without a requirement to write
the corresponding access enable bits first
Enable operation reordering in conjunction with
delayed_read_buffer. See Memory operation reordering on
page A-5.

Semihosting configuration
Semihosting is a method of target software running on the model to communicate with the host
environment. This model allows the target C library to access I/O facilities of the host computer;
file system, keyboard input, clock and so on. For more information see the RealView
Compilation Tools Developer Guide.
These parameters are repeated in groups cpu0-cpu3 for each core in the processor. See
Table 4-35.
