-- init_queue
------------------------------------------
-- This procedure allocates space in the buffer at the given queue_idx.
--
-- - Parameters:
-- - queue_idx - The index of the queue (natural)
-- that shall be initialized.
-- - queue_size_in_bits (natural) - The size of the queue

-- This procedure pushes data to the end of a queue.
-- The size of the data is unconstrained, meaning that
-- it can be any size. Pushing data with a size that is
-- larger than the queue size results in wrapping, i.e.,
-- that when reaching the end the data remaining will over-

--
-- - Returns: The data from the front of the queue (slv). The size of the
-- return data is given by the entry_size_in_bits parameter.
-- Attempting to peek from an empty queue is allowed but triggers a
-- TB_WARNING and returns garbage.
-- Attempting to peek a larger value than the queue size is allowed

-- TITLE: Random Access Memory for Xilinx
-- AUTHOR: Steve Rhoads ([email protected])
-- DATE CREATED: 11/06/05
-- FILENAME: ram_xilinx.vhd
-- PROJECT: Plasma CPU core
-- COPYRIGHT: Software placed into the public domain by the author.
-- Software 'as is' without warranty. Author liable for nothing.
-- DESCRIPTION:
-- Implements Plasma internal RAM as RAMB for Spartan 3x
--
-- Compile the MIPS C and assembly code into "test.axf".
-- Run convert.exe to change "test.axf" to "code.txt" which
-- will contain the hex values of the opcodes.
-- Next run "ram_image ram_xilinx.vhd code.txt ram_image.vhd",
-- to create the "ram_image.vhd" file that will have the opcodes
-- correctly placed inside the INIT_00 => strings.
-- Then include ram_image.vhd in the simulation/synthesis.
--
-- Warning: Addresses 0x1000 - 0x1FFF are reserved for the cache
-- if the DDR cache is enabled.
---------------------------------------------------------------------
-- UPDATED: 09/07/10 Olivier Rinaudo ([email protected])
-- new behaviour: 8KB expandable to 64KB of internal RAM
--
-- MEMORY MAP
-- 0000..1FFF : 8KB 8KB block0 (upper 4KB used as DDR cache)

-- TITLE: Controller / Opcode Decoder
-- AUTHOR: Steve Rhoads ([email protected])
-- DATE CREATED: 2/8/01
-- FILENAME: control.vhd
-- PROJECT: Plasma CPU core
-- COPYRIGHT: Software placed into the public domain by the author.
-- Software 'as is' without warranty. Author liable for nothing.
-- NOTE: MIPS(tm) is a registered trademark of MIPS Technologies.

-- DESCRIPTION:
-- Controls the CPU by decoding the opcode and generating control
-- signals to the rest of the CPU.
-- This entity decodes the MIPS(tm) opcode into a
-- Very-Long-Word-Instruction.
-- The 32-bit opcode is converted to a
-- 6+6+6+16+4+2+4+3+2+2+3+2+4 = 60 bit VLWI opcode.
-- Based on information found in:
-- "MIPS RISC Architecture" by Gerry Kane and Joe Heinrich
-- and "The Designer's Guide to VHDL" by Peter J. Ashenden
-- modified by: Siavoosh Payandeh Azad
-- Change logs:
-- * EPC register have been changed! It used to be R0, now it is R26
-- * added the instruction type and signal for debuging the CPU behaviour!

-- TITLE: Plasma CPU core
-- AUTHOR: Steve Rhoads ([email protected])
-- DATE CREATED: 2/15/01
-- FILENAME: mlite_cpu.vhd
-- PROJECT: Plasma CPU core
-- COPYRIGHT: Software placed into the public domain by the author.
-- Software 'as is' without warranty. Author liable for nothing.
-- NOTE: MIPS(tm) and MIPS I(tm) are registered trademarks of MIPS
-- Technologies. MIPS Technologies does not endorse and is not
-- associated with this project.
-- DESCRIPTION:
-- Top level VHDL document that ties the nine other entities together.
--
-- Executes all MIPS I(tm) opcodes but exceptions and non-aligned
-- memory accesses. Based on information found in:
-- "MIPS RISC Architecture" by Gerry Kane and Joe Heinrich
-- and "The Designer's Guide to VHDL" by Peter J. Ashenden
--
-- The CPU is implemented as a two or three stage pipeline.
-- An add instruction would take the following steps (see cpu.gif):
-- Stage #0:
-- 1. The "pc_next" entity passes the program counter (PC) to the
-- "mem_ctrl" entity which fetches the opcode from memory.
-- Stage #1:
-- 2. The memory returns the opcode.
-- Stage #2:
-- 3. "Mem_ctrl" passes the opcode to the "control" entity.
-- 4. "Control" converts the 32-bit opcode to a 60-bit VLWI opcode
-- and sends control signals to the other entities.
-- 5. Based on the rs_index and rt_index control signals, "reg_bank"
-- sends the 32-bit reg_source and reg_target to "bus_mux".
-- 6. Based on the a_source and b_source control signals, "bus_mux"
-- multiplexes reg_source onto a_bus and reg_target onto b_bus.
-- Stage #3 (part of stage #2 if using two stage pipeline):
-- 7. Based on the alu_func control signals, "alu" adds the values
-- from a_bus and b_bus and places the result on c_bus.
-- 8. Based on the c_source control signals, "bus_bux" multiplexes
-- c_bus onto reg_dest.
-- 9. Based on the rd_index control signal, "reg_bank" saves
-- reg_dest into the correct register.
-- Stage #3b:
-- 10. Read or write memory if needed.
--
-- All signals are active high.
-- Here are the signals for writing a character to address 0xffff
-- when using a two stage pipeline:
--
-- Program:
-- addr value opcode

-- modified by: Siavoosh Payandeh Azad
-- Change logs:
-- * An NI has been Instantiated
-- * some changes has been applied to the ports of the older modules
-- to facilitate the new module!
-- * A specific memory address in external ram has been blocked to be used by the NI
-- * IRQ return address register have been changed! It used to be saved in R0, now it is R26

-- Methods dedicated to this VVC
-- - These procedures are called from the testbench in order to queue BFM calls
-- in the VVC command queue. The VVC will store and forward these calls to the
-- I2C BFM when the command is at the from of the VVC command queue.
-- - For details on how the BFM procedures work, see i2c_bfm_pkg.vhd or the

-- TITLE: Random Access Memory for Xilinx
-- AUTHOR: Steve Rhoads ([email protected])
-- DATE CREATED: 11/06/05
-- FILENAME: ram_xilinx.vhd
-- PROJECT: Plasma CPU core
-- COPYRIGHT: Software placed into the public domain by the author.
-- Software 'as is' without warranty. Author liable for nothing.
-- DESCRIPTION:
-- Implements Plasma internal RAM as RAMB for Spartan 3x
--
-- Compile the MIPS C and assembly code into "test.axf".
-- Run convert.exe to change "test.axf" to "code.txt" which
-- will contain the hex values of the opcodes.
-- Next run "ram_image ram_xilinx.vhd code.txt ram_image.vhd",
-- to create the "ram_image.vhd" file that will have the opcodes
-- correctly placed inside the INIT_00 => strings.
-- Then include ram_image.vhd in the simulation/synthesis.
--
-- Warning: Addresses 0x1000 - 0x1FFF are reserved for the cache
-- if the DDR cache is enabled.
---------------------------------------------------------------------
-- UPDATED: 09/07/10 Olivier Rinaudo ([email protected])
-- new behaviour: 8KB expandable to 64KB of internal RAM
--
-- MEMORY MAP

-- This test case will show how using VVCs in UVVM can be used for simultaneous UART and SBI operation,
-- which enables testing of corner cases. In the UART DUT one of these corner cases often occurs when the UART DUT
-- must handle UART RX data and SBI reads simultaneously. To test if this is handled properly in the DUT,
-- this test case will transmit data from the UART VVC, and check the data received in the C_ADDR_RX_DATA register.
-- The DUT RX buffer will always contain at least one received byte, and the SBI VVC will check the oldest entry in
-- the RX buffer. The UART VVC will be set up to transmit bytes to the DUT continuously. When the SBI_VVC checks the
-- DUT RX buffer, relative to the UART TX operation, will vary on each iteration.
-- First, the UART VVC will transmit a complete frame to the DUT. Then, when the UART VVC is 50 clock periods from
-- completing the transmission of the second byte, the SBI VVC checks the DUT RX buffer for the first received byte.
-- When the UART VVC is 49 clock periods from transmitting the third byte, the SBI VVC will check the DUT RX buffer
-- for the second byte received. This process repeats until the SBI VVC is checking the DUT RX register 50 clock periods
-- after the UART VVC has completed its transmission. At this point there will be two complete bytes in the DUT RX buffer
-- when the SBI VVC reads from it. After the test is completed the two final bytes in the RX buffer are checked. When this
-- is done, the test case is complete.
