a) Programmable Read-Only Memory (PROM) is a computer memory chip which is programmable once it is created and the information cannot be erased Implement the following Boolean functions using PROM. F1(A1, A0) = F2(A1, A0) = m(3,5,7), m(4,5,7) Major Topic Programmable Read Only Memory (PROM) Blooms Designation AP Sobre

the available space list of a computer memory is specified as follows: 9 start address block address in words 100 50 200 150 450 600 1200 400 determine the available space list after allocating the space for the stream of requests consisting of the following block sizes: 25,100,250,200,100,150 use i) first fit ii) best fit and iii) worst fit algorithms

Please answer all the following questions. 1. In a hypothetical computer, the processor has four registers: an 8-bit Program Counter (PC), a 16-bit Accumulator (AC), a 16-bit Counter (CTR), and a 12-bit Pointer (PTR). The memory is divided into words each of which is 16-bit long. Each word can hold either an instruction or a piece of data. For each instruction X, the four most significant bits (denoted by X15-12) represent an opcode. The rest of the instruction (denoted by X11-0) can be either an address or a value of an operand. The table below explains some of the instructions supported by the processor. Opcode (binary) 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 Operation Load AC from a memory location whose address is X11-0. Store AC into a memory location whose address is X11-0. Add to AC the contents of a memory location whose address is the value of PTR. The result is saved to AC. 1100 Subtract from AC the contents of a memory location whose address is the value…

RAM stands for Random Access Memory, whereas Register refers to a different kind of memory altogether.

Features of Memory Consider the following array of memory cells (our logisim cells included the AND gate attached to the WE input in the cell subcircuit, but this is not relevant here). WE A 1100101011111110 1010111110101101 1010110110101101 1011111010101110 Fill in the correct output values (either 1 or 0) for the specified input values. a) What is the addressability (in bits) of this array? b) What is the address space of this array? c) What is hex(with an x)adecimal value with address 01?

The time taken to access registers is less than the time taken to access memory. True False
