Introduction edit
Instruction set architecture edit
We have several formats for the instruction set, as the operations needs different inputs
Type 1:
| Instruction | Opcode | Destination register | Source register | Source register | Usage
|
|---|---|---|---|---|---|
| add | 0001 | Rd | Rs | Rt | Rd ← Rs + Rt |
| mult | 0011 | Rd | Rs | Rt | Rd ← upper part(Rs x Rt), Rd+1 ← lower part(Rs x Rt) |
| sub | 1010 | Rd | Rs | Rt | Rd ← Rs - Rt |
Type 2:
| Instruction | Opcode | Destination register | Source register | Source register | Usage |
|---|---|---|---|---|---|
| Immediate load | 0010 | Rd | imm | imm | Rd ← imm |
Type 3:
| Instruction | Opcode | Destination register | Source register | Source register | Usage |
|---|---|---|---|---|---|
| shift left | 0111 | Rd | Rs | shamt | Rd ← Rs << shamt |
| shift right | 1000 | Rd | Rs | shamt | Rd ← Rs >> shamt |
| negation | 1011 | Rd | Rs | XXX | Rd ← -Rs |
| load | 1110 | Rd | Rs | imm | Rd ← mem[Rs(imm)] |
| store | 1111 | Rd | Rs | imm | mem[Rd] ← Rs |
Type 4:
| Instruction | Opcode | Destination register | Source register | Source register | Usage |
|---|---|---|---|---|---|
| branch equal | 1100 | address | flag value | flag enabled | if (flag value == ALU flags){next PC ← address} |
| branch return | 1101 | address | flag value | flag enabled | if (flag value == ALU flags){next PC ← address; push stack ← curr PC} |
Type 5:
| Instruction | Opcode | Destination register | Source register | Source register | Usage |
|---|---|---|---|---|---|
| jump to return | 0110 | XXX | XXX | XXX | next PC ← pop stack |
| nop | 0000 | XXX | XXX | XXX | no operation |

Leros edit
Martin Schoeberl (no group - this is just a template ;-)
An FPGA optimized tiny processor core for utility functions (e.g., SW UART). The challenge is to get the resources below 500 LC and use just 2 RAM blocks. The processor is named after the Greek island Leros where the architecture was designed. Details of the design can be found at the Leros processor page.
Perhaps I will do this design along the course to see how much work the assignment actually is ;-)
