Vector Registers

Intel® Streaming SIMD Extensions (Intel® SSE) operations use data types that are vectors of integers and floating point numbers, which can be modified in single instructions. The Vector Registers window displays the register values as vectors in various formats as supported by the Intel® SSE instruction set.

By default, the first column displays the id of all registers of a particular size, such as INT8, INT16, INT32, INT64, FLOAT32, or FLOAT64. The other columns display the vector iteration for each register in chunks of 1, 2, 4 and 8 bytes either displayed as an integer or a floating point number.


To edit a register value, double-click it.


The window is not supported for 64-bit applications.

Pop-up Menu


Select Size to select the desired display type for an iteration, such as INT32.


Select Format to select the desired display format for an iteration, such as hexadecimal. The format can only be changed for integer iterations, for FLOAT32|64, the format is fixed to float.

Column Resizing

Select Column Resizing to select an appropriate column display:

Fit to Window
