The "sra" operator is not defined for all types in numeric_std. You have to do some casting to get what you want. 2019-12-11 VHDL OPERATORS C. E. Stroud, ECE Dept., Auburn Univ. 2 8/06 Misc. Operators ** exponentiation left operand = integer or floating point right operand = integer only abs absolute value not inversion Shift Operators sll shift left logical (fill value is ‘0’) srl shift right logical (fill value is ‘0’) For VHDL, you can use only predefined shift (sll, srl, rol, etc.) or concatenation operation. Please refer to the IEEE VHDL language reference manual for more information on predefined shift operations.

Table 1. VHDL stands for Very High-Speed Integration Circuit HDL (Hardware Description Language). It is an IEEE (Institute of Electrical and Electronics Engineers) standard hardware description language that is used to describe and simulate the behavior of complex digital circuits. SRL : (Shift Right Logical) result <= vect srl 1 output : vect In vhdl the shift registers are defined only for one dimensional arrays of bit or boolean. The VHDL Operators Highest precedence first, left to right within same precedence group, use parenthesis to control order. Unary operators take an operand on the right.

Synchronous FIFO's based upon the SRL feature found in Xilinx FPGA's. Built to be small.

It normally executes logic and arithmetic operations such as addition, subtraction, multiplication, division, etc. In this VHDL project, an ALU is designed and implemented in VHDL. Hi, SRL & Co. are neither supported by the std_logic packages nor by numeric_std packages.

Description. Synchronous FIFO's based upon the SRL feature found in Xilinx FPGA's. Built to be small. In a Spartan 3, the 8 bit wide , 16 bit deep FIFO utilises 19 Luts of which 8 are used as SRL, 11 as Logic.

The VHDL Operators Highest precedence first, left to right within same precedence group, use parenthesis to control order. Unary operators take an operand on the right. "result same" means the result is the same as the right operand.
