+//     			Mailbox32bit = {8'b0, MailBox[7:0], 16'h0};

+//		5. Expected the Synthesis to remove all unused logics
+//
+// 11-29-2013	   1.2        Anthony Le	 Add additional comparison functions

+//         b. JMPNEZ: jump when result is not equal to zero
+//         c. JMPGEZ: jump when result is greater or equal to zero
+//		2. Add four more compriason jump functions
+//         a. JMPEQZ: jump when result is equal to zero
+//         b. JMPLTZ: jump when result is less than zero
+//         c. JMPLEZ: jump when result is less than or equal to zero
+//         d. JMPGTZ: jump when result is greater than zero
+//	    3. Re-use the three control signals[19:17]
+//      4. Use an 8-to-1 mux for JUMP logic
+//      5. Update xJumpFlag from wire to reg type

+ History  :
+ Date         Version   Author       Description
+ 2013/03/21   1.0       Jason Lew    Created
+ 2013/05/02   1.1       Jason Lew    Migrated from FFEAT v21d
+ 2013/06/14   1.2       Randy O.     Corrected assignment to DataMemReadAddr's b/c it wasn't using IndexReg properly.
+                                     Corrected assignment to MemReadData's b/c it shouldn't use IndexReg.
+ 2013/06/26   1.3       Randy O.     Made the Signals bus 64 bits wide instead of 32, since it needs to be at least as wide as the one in microopdecodes.v
+ 2013/07/01   1.4       Randy O.     Cosmetic changes to improve readability.
+                                     Removed DataMem1WriteData_int & DataMem2WriteData_int since they were unused.
+ 2013/07/08   1.5       Randy O.     Added unit delays to aid in functional sim.
+ 2014/05/21   1.6       Glen  G.     Added ability to read/write expanded Sensor Manager Memory
+
+ -----------------------------------------------------------------------------
+ Comments: This solution is specifically for implementing into the Alabama
+           test chip. Verification will be done using the Jim-Bob Sensor Board

+SPI_slave
+	SPI slave interface, designed for the ULP Sensor Hub.
+	This module is designed to be as small and simple as possible, while
+	supporting the ULP Sensor Hub. Only supports SPI Mode 0 (CPOL=CPHA=0)...
+	which means that input data is latched on the positive edge of SPI_SCLK,
+	and driven out on the negative edge of SPI_SCLK, with the base value of
+	SPI_SCLK being 0.
+
+
+	SPI Protocol:
+		Writes:		MOSI: A0 + D0 + D1 + ... + Dn
+					MISO: xx + xx + xx + ... + xx
+
+		Reads:		MOSI: A0 + xx + xx + ... + xx
+					MISO: xx + xx + D0 + ... + Dn
+
+		A0 = [1-bit R/W: 1=write, 0=read] + [7-bit address]
+		Dn = valid data byte
+		xx = don't-care data byte
+
+		It is assumed that the MSb is transmitted first, and the LSb last.
+
+		The address is latched, and auto-incremented to support burst reads/writes.
+		The address, when 0d11, jumps back to 0d07, to support repeated (burst)
+		reads to/from the memory data port. The logic to re-map addresses above
+		0d11, that previously was in TLC.v, can now be removed. New registers
+		above 0d11 may now be added if needed.
+
+		This SPI slave requires extra edges on SPI_SCLK to complete any write
+		operation. This may be accomplished in any one of several ways:
+			1. A (non-destructive) read should be performed following the last
+			   write operation.
+			2. SPI_SCLK should be toggled after SPI_SS goes inactive
+			   (a free-running SPI_SCLK would accomplish this).
+			3. A few extra bits (totaling less than a full byte) should be
+			   transmitted by the master. These extra bits will be ignored by
+			   this core, but will provide the clocks needed to generated the
+			   wr_data_valid pulse.
+			4. A "null" transaction should be performed following the last
+			   write transaction, during which the address byte is transmitted
+			   by the SPI master followed by 0 bytes of read/write data.

+//		Assumptions:
+//			Ring osc range: 25.2MHz - 53.2MHz (39.7ns to 18.8ns period)
+//			I2C master will divide clk_main by 9 to produce SCL.
+//			SCL freq cannot exceed 400KHz.

+	// desired quality.                                               //
+	// The JPEG-standard compliance specs.(ITU-T.83) prescribe        //
+	// that the output of the combined DCT AND Quantization unit      //
+	// shall not exceed 1 for the desired quality.                    //
+	//                                                                //
+	// This means for high quantization levels, lesser bits           //
+	// for the DCT unit can be used.                                  //
+	//                                                                //
+	// Looking at the recommended "quantization tables for generic    //
+	// compliance testing of DCT-based processes" (ITU-T.83 annex B)  //
+	// it can be noticed that relatively large quantization values    //
+	// are being used. Errors in the lower-order bits should          //
+	// therefore not be visible.                                      //
+	// For certain applications some of the lower-order bits could    //
+	// actually be discarded. When looking at the luminance and       //
+	// chrominance example quantization tables (ITU-T.81 annex K)     //
+	// it can be seen that the smallest quantization value is ten     //
+	// (qnt_val_min = 10). This means that the lowest 2bits can be    //
+	// discarded (set to zero '0') without having any effect on the   //
+	// final result. In this example 11 bit or 12 bit coefficients    //
+	// would be sufficient.                                           //
