Using the symbol table on the right, write the corresponding LC-3 machine langua

Question

Using the symbol table on the right, write the corresponding LC-3 machine language word (16 bits, binary) for each assembly language statement below. Assume in each case the instruction/data word is located at address x3010. (In other words, this is NOT a sequence of instructions.) If a translation cannot be performed with the information given, write ILLEGAL in the blank space.

xNumber The number in hexadecimal notation. #Number The number in decimal notation. A[l:r] The field delimited by bit [l] on the left and bit [r] on the right, of the datum A. For example, if PC contains 0011001100111111, then PC[15:9] is 0011001. PC[2:2] is 1. If l and r are the same bit number, the notation is usually abbreviated PC[2]. BaseR Base Register; one of R0..R7, used in conjunction with a six-bit offset to compute Base+offset addresses. DR Destination Register; one of R0..R7, which specifies which register the result of an instruction should be written to. imm5 A 5-bit immediate value; bits [4:0] of an instruction when used as a literal (immediate) value. Taken as a 5-bit, 2
