The internal memory for the slave is defined as a sparse array of 8-bits, so that each byte of data

is stored as an address/data pair.

Example 6-17. internal memory

// Storage for a memory

bit [7:0] mem [*];

The do_byte_read() function, when called, reads a data byte from the internal memory, mem,

given an address location as demonstrated in Example 6-18.

You can edit this function to modify the way the read data is extracted from the internal

memory.

Example 6-18. do_byte_read()

// Function : do_byte_read

// Function to provide read data byte from memory at

// particular input address

function bit[7:0] do_byte_read(addr_t addr);

return mem[addr];

endfunction

The do_byte_write() function, when called, writes a data byte to the internal memory, mem,

given an address location as Example 6-19 illustrates.

You can edit this function to modify the way the write data is stored in the internal memory.

Example 6-19. do_byte_write()

// Function : do_byte_write

// Function to write data byte to memory at particular

// input address

function void do_byte_write(addr_t addr, bit [7:0] data);

mem[addr] = data;

endfunction
