3.5 Instruction Set for the MaverickCrunch Co-Processor
Table 3-10 summarizes the MaverickCrunch co-processor instruction set. Please note that:
CRd, CRn, and CRm each refer to any of the 16 general purpose MaverickCrunch
registers unless otherwise specified
CRa refers to any of the MaverickCrunch accumulators
Rd and Rn refer to any of the 16 general purpose ARM920T registers
<imm> refers to a seven-bit immediate value
The remainder of this section describes in detail each of the individual MaverickCrunch
instructions. The fields in the opcode for each MaverickCrunch instruction are shown. When
specific bit values are required for the instruction, they are shown as either '1' or '0'. Any field
whose value may vary, such as a register index, is named as in the ARM programming
manuals, and its function described below.
