Your task is to write an E20 assembler: a program that will convert E20 assembly language into E20 machine language. Each E20 assembly language instruction can be expressed as a 16-bit E20 machine language instruction. The rules for converting between the two forms is given in the E20 manual, particularly the chapter on the E20 instruction set. For example, consider the assembly language instruction addi $1, $2, 3. The opcode is addi, used for performing addition of an immediate. In this case, we are adding the number 3 to the value currently stored in register $2, and storing the result into register $1. The corresponding machine code instruction is 1110100010000011 in binary, or 59523 in decimal, or e883 in hex. Each component of the assembly language instruction maps onto a region of its machine language counterpart.

Convert and simplify the following sentences to conjunctive normal form (cnf): (a) (p → (q → r)) → (p → (r → q)) (b) (p ∧ q) → (¬p ↔ q) (c) ((p → q) ∧ ¬q) → ¬p

Signal sets company contracts to deliver one hundred 52-inch plasma high-definition television sets to a new retail customer, tuner tv store, on may 1, with payment to be made on delivery. signal tenders delivery in its own truck. tuner's manager notices that some of the cartons have scrape marks. tuner's owner phones signal's office and asks whether the sets might have been damaged as they were being loaded. signal assures tuner that the sets are in perfect condition. tuner tenders signal a check, which signal refuses, claiming that the first delivery to new customers is always for cash. tuner promises to pay the cash within two days. signal leaves the sets with tuner, which stores them in its warehouse pending its "grand opening sale" on may 15. two days later, tuner's stocker opens some of the cartons and discovers that a number of the sets are damaged beyond ordinary repair. signal claims tuner has accepted the sets and is in breach by not paying on delivery. will signal succeed on these claims? explain.
