+EQU - when defining a variable with EQU we are stating define
+
+a_len EQU (. - a) / 4 ; we are stating . means current byte, a is the start of a and divide by 4 because each element in a is 4 bytes. This would only work when defined right after a value.
+
+ldrsb - load register signed byte
+
+[] - Square brackets load the value associated with the pointer in a register ie. [R0] = value at memory position specified by R0.
