Thirty-two 64-bit FPRs for single- or double-precision operands
– Four vector units and 32-entry vector register file (VRs)
Vector permute unit (VPU)
Vector integer unit 1 (VIU1) handles short-latency AltiVec integer instructions, such as
vector add instructions (for example, vaddsbs, vaddshs, and vaddsws).
Vector integer unit 2 (VIU2) handles longer-latency AltiVec integer instructions, such as
vector multiply add instructions (for example, vmhaddshs, vmhraddshs, and vmladduhm).
Vector floating-point unit (VFPU)
– Three-stage load/store unit (LSU)
Supports integer, floating-point, and vector instruction load/store traffic
Four-entry vector touch queue (VTQ) supports all four architectures of the AltiVec data
stream operations
Three-cycle GPR and AltiVec load latency (byte, half word, word, vector) with one-cycle
throughput
Four-cycle FPR load latency (single, double) with one-cycle throughput
No additional delay for misaligned access within double-word boundary
Dedicated adder calculates effective addresses (EAs)
Supports store gathering
Performs alignment, normalization, and precision conversion for floating-point data
Executes cache control and TLB instructions
Performs alignment, zero padding, and sign extension for integer data
Supports hits under misses (multiple outstanding misses)
Supports both big- and little-endian modes, including misaligned little-endian accesses
Three issue queues, FIQ, VIQ, and GIQ, can accept as many as one, two, and three instructions,
respectively, in a cycle. Instruction dispatch requires the following:
– Instructions can only be dispatched from the three lowest IQ entries: IQ0, IQ1, and IQ2
– A maximum of three instructions can be dispatched to the issue queues per clock cycle
– Space must be available in the CQ for an instruction to dispatch (this includes instructions
that are assigned a space in the CQ but not in an issue queue)
