Study Notes
Operations of the Computer Hardware
- Instruction representation in programming languages, focusing on C and object-oriented languages like Java.
- The stored-program concept underlines that instructions and data can be stored in memory as numbers, facilitating flexibility and optimization.
- RISC-V, an open architecture managed by RISC-V International, boasts membership from over 200 companies, highlighting its growing popularity.
- Arithmetic operations are fundamental; RISC-V assembly language enforces strict syntax with three operands per instruction.
- Example of RISC-V addition:
-
add a, b, c: Adds variables b and c, storing the result in a. - Multiple instructions are required to sum more than two variables.
-
- Comments in RISC-V are marked with double slashes (//) and are line-specific.
- Simplicity in hardware design is emphasized; each instruction follows the rule of exactly three operands for consistency and ease of hardware implementation.
- Higher-level languages like C or Java can be translated into RISC-V assembly, illustrating the relationship between complex programming and simpler machine codes.
- Two given C assignment statements translated into RISC-V:
-
a = b + cbecomesadd a, b, c -
d = a - ebecomessub d, a, e
-
- Example of a more complex C assignment:
-
f = (g + h) - (i + j)requires several RISC-V instructions using temporary variables:-
add t0, g, handadd t1, i, jto create sums, followed bysub f, t0, t1.
-
-
- Compiling complexity shows the necessity of multiple instructions for single high-level operations, showcasing the detailed nature of assembly programming.
