Bit slice indexing

WebI am new to indexing arrays in VHDL and there is a lot of information on online forums on how to access a bit in an element. However how do you access a group of bits in an array element. My guess would have been the following: declaration: type mem is array (0 to 7) of STD_LOGIC_VECTOR(255 downto 0); Bit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n-bit central processing unit (CPU). Each of these component modules processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a given software design.

For example, the slice a[8:] has exactly 8 bits. Likewise, the slice a[7:2] has 7-2=5 bits. You can think about it as follows: for a slice [i:j], only bits below index i are included, and the bit with index j is the last bit included. columbia il calendar of events
